In cases, we design and manufacture mobile crushing plant which brings new life to the construction waste.

As the rapid development of society, the fundamental Infrastructure has gradually expanded the scale .The old things are being replaced by the new one, especially the concrete buildings and the comparatively narrow roads. In this process, more and more construction wastes are produced, and in the last time, these building wastes were transported to the area far away from city, or just thrown away everywhere, polluting the environment.

However, in these days, these things have their new function instead of just the construction waste. They are transferred into the construction aggregates just at the working site, and through the first crushing, secondary crushing, sometimes needs the tertiary crushing process, and the screening, sometimes may need grinding, the final products can be transported to the construction site directly.

It is the mobile crusher plant that brings all these changes. It is designed to help the customers change the working site conveniently compare to the stationary one. Nowadays the mobile crushing plant is being more and more popular in many aspects, say the ore mine, the waste process and so on.

And of course, it's not enough for future development and we are insisting our management theory and service spirit to make considerable progress.

Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. Compare with jaw crusher, cone crusher is of stable structure, high efficiency, easy adjustment, economic operation, etc.

Spring cone crusher is cone crusher which is the earliest appearance in the world, and it is used widest and larger quantity crush mechanism at present. The Spring Cone crusher is generally used as a secondary crusher in a stone production line. The spring safety system of crusher acts as an overloading protection system that allows metal to pass through the crushing chamber so as not to damage the cone crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separate to make sure reliable performance. The type of crushing chamber depends upon size of feeding and fineness of crushed product. The standard type (PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.

With the development of the series of spring cone crusher, its structure is more perfect than before and the technology parameter is more advanced, so these crushers have excellent performance in the aspects of manufacture, installation, use and maintenance etc. The spring cone crusher belongs to the cone crusher, in the stone production line, there are some other crushers such as jaw crusher, impact crusher, vibrating feeder and vibrating screen.

Spring cone crushers are widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc. The standard spring cone crushers are used for secondary crushing; the medium ones are used for fine crushing; and the short head ones are used for super thin crushing. The spring cone crusher is characterized by a reliable structure, high efficiency, easy adjustment and economic. The spring safety system prevents overload so that hard materials (such as iron) are processed through the crushing chamber without damaging the machine. Spring cone crushers are run on belt drives driven by an electric motor or diesel engine. Cone crushers are used extensively throughout the aggregate and mineral processing industry.

The working principle of spring cone crusher: spring cone crusher crushes materials by the working surface between the movable cone and fixed cone. So spring cone crusher is more advanced and efficiency. The movable cone is supported by spherical bearing and fixed on an hanging vertical shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and vertical shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined.

Compared with jaw crusher, spring cone crusher has the advantage of low operation costs, high productivity, easy adjustment and stable structure. The spring cone crusher has higher capacity and the products with high quality. Because spring cone crusher has safety device, the parking time has been reduced greatly. The machine is cast steel structure and on the heavy load pat equip with dabber. The spring cone crusher equips with adjuster, it can adjust the discharge particle size to meet different demands. The spring cone crusher has a whole lubrication system, it can self-close once the oil temperature is too high or overflow. The inner structure of spring cone crusher has good sealing property. This will protect spring cone crusher from damage of dust. Spring cone crusher has long using life and high applicability. This spring cone crusher can be equipped with other equipments in the stone production line or sand making production line.

The VSI sand maker machine made sand is made of river cobble and cobblestone, and processed by crusher machines and VSI sand makers, or other accessory equipments. This artificial sand can replace the natural sand, and even much better for construction than the natural sand.

Henan Hongxing is a manufacturer who produces the VSI sand makers based on the various processing requirement as well as the sand particle size, VSI sand maker can further meet the day-to-day needs of mining operating location. The VSI sand maker is broadly employed within high way, railway transport, water conservancy as well as other sectors. This VSI sand maker is suitable for metal and nonmetal ore, construction material, artificial sand as well as other types of metallurgy slag. This VSI sand generating machine is used inside the brittle material using the moh’s hardness much less than 9 degree, it not suitable for the viscous material or the stone material with a lot of soil.

Based on the above, it's the issue that how to choose the correct and proper VSI Sand Making Machine.

From the technological requirement, sometimes people just require the maximum particle size limited value, the fine powder can not exceed the limited value. Sometimes people not only require the particle size, but the particle shape. So the requirement of VSI sand maker is also strictly. For example, as the concrete aggregate, there is not only requirement on the product particle size, but also require the particle shape must be cubic. It is better with edge angle, this can promote the strengthen of concrete. In the sand making production line, the products particle size must be ensure by the third generation sand making machine-VSI high efficiency sand maker. As used for steelmaking material, limestone particle size must be controlled in a certain range, and not or less produce the powder.

In addition, the main consumption of VSI sand maker, inside the crushing plant, besides the typical wears of VSI sand maker, electric energy, steel consumption, lubrication, water and rubber belt are the primary consumption aspects. The consumption volume is distinct according to the ore constitute, mine sort, hardness, crushing flow and crushing ratio. So to be able to minimize power consumption, inside the crushing plant, folks should boost the processing capacity of each stage, reduce the VSI crusher empty operation to achieve the best economy benefit and lower the unit consumption.

Henan Hongxing connects the informatization technology and improved the work efficiency to solve the VSI sand makers problem, this promoted the VSI sand maker crushing ratio and reduced the wear and energy consumption. At the present condition of economic development, the VSI sand makers will have high use value in the mining machinery industry.

Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated by froth flotation typically to 70% or more. When lead is exploited to the ground, it’s should be crushed or grinded for its further application. Lead ore crusher will act as the primary crushing equipment in lead ore crushing plant So now the PEW sequence of Jaw crusher has most unquestionably change to the earth most welcome crusher .And you might make your mind up upon the PEW sequence of jaw crusher while using earth superior crushing and production solutions as quickly when you desire to crush the products featuring very hard and big erosion.

We can supply many lead ore curshers such as lead jaw crusher, lead impact crusher, lead cone crusher, lead mobile crusher and so on. Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. Lead ore crushers are used widely in such ore curshing industry. Since the establishment, Hongxing has grown to become the largest crusher and screening equipment dealer in the China. So, if you want some lead ore or other ore mining equipments or crushing machines, you can come to visit Hongxing which must be your good choice.

Lead oxide from the roasting process is reduced in a coke-fired blast furnace.[6] This converts most of the lead to its metallic form. Three additional layers separate in the process and float to the top of the metallic lead. These are slag (silicates containing 1.5% lead), matte (sulfides containing 15% lead), and speiss (arsenides of iron and copper). These wastes contain concentrations of copper, zinc, cadmium, and bismuth that can be recovered economically, as can their content of unreduced lead.

Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the contaminants except silver, gold, and bismuth. The oxidized contaminants are removed by drossing, where they float to the top and are skimmed off.

Lead hammer crushers are widely used in small quarries with small capacities. That’s because in such situation, the cost and the difficulty of changing and maintaining worn hammers are more acceptable to the quarry owners. However, once the quarry owners want to enhance the capacity to above 50-60t/h by one crushing plant, hammer crushers are no longer suitable. Using hammer crusher to do a big crushing work will lead to a passive situation .

Global mining firms are unearthing ingenious solutions to grapple with shortages of workers and equipment amid the commodities boom, recruiting retired miners and buying cut-rate equipment from China and Russia, executives said this week. 'We hired some guys out of retirement, that was the only way to survive and get the skills in place,' said Pekka Pera, chief executive of Talvivaara, a Finnish firm building a new nickel and zinc mine.

Mining firms innovate to cope with labour and equipment shortages Eric OnstadMining firms, trying to cope with shortages of skilled workers and equipment, have been forced to innovate and adopt new solutions, rehiring retired mineworkers and buying cheaper equipment from China and Russia.

Different mining firms in different countries have various methods and policies.

Pera and other executives told the Reuters Global Mining Summit the key was taking advantage of local situations to surmount obstacles thrown up by a global rush to build new mines as metal prices soar to fresh peaks.

The Finnish firm realised that the depressed region around the mine had a lot young untrained and unemployed people, but also a number of retired miners.

Training and keeping workers was the biggest challenge for Major Drilling Group, one of the world's biggest mine drilling companies, Chief Executive Francis McGuire said.

'It takes three to five years to train a driller and it is a very, very skills intensive industry,' he said.

On the equipment side, Peter Hambro, executive chairman of the Russian gold producer that carries his name, said his firm had slashed costs by local purchasing.

The tyre situation has improved, but a lack of them was one reason behind a fall in production last year at the world's biggest diamond mines in Botswana, said Sheila Khama, the head of De Beers in that country.

Right now, big shortages and long lead times were being seen in mills, said Peter Marrone, chief executive of Canada's Yamana Gold.

His firm managed to keep expansion projects on schedule by ordering mills even before the board had formally approved building the new mines.

Construction waste recycling is to different crushing equipment, screening equipment, transmission equipment and equipment to remove impurities with a reasonable production assembly process.

Construction waste in many of the waste by sorting, removed or crushed, most of them can re-use as a renewable resource. Such as scrap steel, scrap wire, scrap wire and other metal by sorting, concentration, re-melted, it can be processed into all kinds of steel; waste bamboo, wood can be used to make artificial wood.

If enterprises can reuse and recycle construction waste well, the crushing equipment productivity must be pushed forward. Of course, in addition to this aspect, influence of crushing equipment productivity there are many factors, including internal and external factors, internal is broken, the functions and characteristics of mechanical itself is material properties outside influence. Specific as follows:

1) material of hardness. The more hard material broken up, and the more difficult for equipment wear and tear the more serious. Broken slow, of course, crushing small ability.

2) materials, namely material containing the humidity of moisture is bigger, within easy adhesion material in crusher, also easy to next material transporting process jams, causing broken ability decrease.

3) crushing the fineness of materials, high fineness requirement, which requires broken out of the fine, the material crushing ability and smaller.

4) material composition, the broken in the former materials containing powder more many more influence, because these fine powder crushing to affect delivery. Adhesion For fine powder content more should advance once sieve.

5) material viscosity. Namely material viscosity, the bigger the more easily adhesion.

6) crushing equipment broken pieces (hammer) wear resistance, the better broken, the greater the if not wear-resisting ability will affect the crushing ability .

The advanced technology is the main factor of development, the development in China of the urban and rural is a kind of solidarity, they are promoted each other and influenced each other. While the R & D of new sand making machine will make the township economic in our country develops rapidly. New sand making machine is one of the ideal equipment producing mechanism sand, cushion material, asphalt concrete and cement concrete aggregate. Which is widely used in highway, construction and other fields and called new sand making machine for impact crusher. New sand making machine is grinding and crushing materials by the material mutual collision and friction between materials, therefore it is suitable for the coarse and hard crushing of hard, medium hard and abrasive materials.

Sand making machine is the equipment which makes sand artificially. It can be impact crusher or cone crusher according to the materiel condition and production requirement.

In the working process of the new sand making machine, a swirling crushing chamber is particularly important; the structure shape of the swirling crushing chamber structure shape is a annular space composed by the upper and below two cylinder. The crushing of the materials proceeds in swirling crushing chamber and the crushing effect is limited to the materials, which can play a role of to wear resistant as a lining; the observation hole is used for observing the wear pattern of the wear-resistant block in the impeller emission outlet flow passage and the linear at the top of swirling crushing chamber, the observation must be strictly sealed when the machine works; the distributor is fixed to the upper cylindrical of the swirling crushing chamber; when the impeller rotates at high speed, it will generate air flow which will through the distributor in swirling crushing chamber and the impeller forms internal self circulation system; at last the fine material will discharge out from the opening.

The sand making machine is especial suitable for making building sand and paving sand. Because of its low wearable feature, sand making machine is also used in high abrasiveness and secondary crushing industry. Besides, because there is no pollution for machine, sand making machine is well suitable for producting glass quartz sand and other high purity material industry. Its production capacity scopes is 10-500t/h., so sand making machine almost can satisfies all production requirement.

With the continuously development of Chinese economy, the machinery industry has continued to expand and the machinery is widely applied to large-scale construction, believe that after many years' experience in the mineral processing equipment production areas, we will provide more perfect and excellent performance sand or gravel production line for the market. I believe that in the near future China's development will be more quickly, rural development will make a spurt of progress.

A computer simulation, a computer model, or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics (computational physics), astrophysics, chemistry and biology, human systems in economics, psychology, social science, and engineering.

It is from the last century that people from foreign country had optimized the structure and cavity of the jaw crusher by the computer simulating technology, they had developed the new jaw crusher with characteristics of no plug point, low height, light weight, good product particle, high yield, high performance and low power consumption, which thereby greatly improved the performance of the jaw crusher, shortened the developing cycle of product and improved the competitiveness of the product in the market. However, the simulating optimization design of the jaw crusher in China was mainly limited to the specific models of jaw crusher to prepare the corresponding procedure to optimize the design. And these procedures are mostly with little reusability, which can only solve the specific issues of particular jaw crusher. However, the optimized content of a crusher changes frequently with different requirements of different customers, so the simulation optimization design work needs large repeated and cumbersome programming work, which is time-consuming and laborious as well as extends the developing cycle of the product.

Jaw crusher is widely used in mining, metallurgy, building materials, highway, railway, water and chemical industries. Among them some large and medium-sized the jaw crushers are the main products. Especially in designing and producing large jaw crusher, we has been a leading level at home and abroad. Try to use the advanced design tools of kinematics and dynamics simulation to have a rapid development of the new jaw crusher and to have a simulating optimization design of the mechanism design parameters, which greatly reduce the workload of the simulation design, shorten the product development cycle and improve the reusability of the simulating model. To optimize the jaw crusher by the use of simulating technology, the main task is to optimize the feeding, discharging horizontal and vertical stroke and stroke characteristic coefficient of a jaw crusher.

Computer simulations are used in many fields, including science, technology, entertainment, health care, and business planning and scheduling. With this high technology, we believe that our mining equipments will get better performance.

The bearing of general large jaw crusher mainly uses the open sliding bearing. The bearing liner is mostly made of Babbitt alloy, the scraping technical of this kind of bearing has a higher requirements. If the scraping is not good or gap adjusted improperly, there can cause burning watt accident.

In process of replacing the bearing of large jaw crusher, we should pay attention to the following points:

A. What should we do when remove the old watt of jaw crusher.

(1) Measure the thickness of the old bush joint surface gasket.

(2) Measure the levelness of the spindle.

(3) Examine whether the spindle is smooth or not, and whether it with the defects of rust, bumps and so on or not. If the situation is exist, you should to eliminate it.

(4) Measure the of the bottom clearance, backlash and end clearance of the bearing bush.

B. Testing of the contact of the watt-back with the bearing of the jaw crusher.

In order to prevent happening of the reverse sliding and rotating between the bearing bush and the bearing pedestal when the equipment operation, it generally adopts the pin, sleeve positioning mode.

C. The techniques requiring of the scraping the bearing bush.

Spindle scraping should meet the required standards of technical.

D. Scraping and grinding the spindle bush.

The scraping is generally divided into rough scraping, fine scraping and refined scraping three processes.

E. The measurement and the adjusting method of the bearing clearance.

Reasonable adjust bearing clearance is an important issue, it must meet specified standards

The general adjusting methods include: top clearance adjusting and measuring methods, side gap adjusting and measuring methods, the axial clearance measuring method.

F. The assembly and test.

When assemble the jaw crusher, clean the bearing bush, shaft, oil collector and lubricating oil pipeline at first. Then assemble the main bearing, connecting rod and other components. When testing, actuate the pump, and ensure the amount of fuel supply slightly bigger than that of normal operation. As in the process of testing does not appear the phenomenon that the temperature is elevated and the current significantly increased, that proves the success of the overhaul, then the equipment can be used normally.

In the course of operating jaw crusher, sometimes the jaw crusher parking condition can be met suddenly. At this time, if the operator can not find the reason of jaw crusher parking and repair it immediately, the greater damage will be caused and all of stone product must be forced stop operation, so the abnormal jaw crusher parking will bring great loss for enterprise. Well, why the jaw crusher parking and how to deal with this situation are very important.

(1). In the process of jaw crusher operation, some workers will keep adding to the ore material to feed the inlet. As a result, the feeding material will be more than the carrying capacity of the machine, it will cause a blockage of the inlet. The jaw crusher parking will happen in this situation, the operators must clean up the crushing cavity before restarting, and evenly feed the material to avoid jaw crusher parking.

(2). Jaw Crusher is transmitted power by the drive belt, so if improper belt tension will cause jaw crusher parking. So the belt should be checked before you start the machine each time to see if the under belt is appropriate.

(3). Timely check up all the bolts of jaw crusher machine, the loosen bolts also can cause jaw crusher parking in the course of operation.

Here, we also introduct some preparation work before using jaw crusher.

(1) double-check whether good lubrication of bearings, thrust plate connections have enough grease.

The vibrating screen installation and debugging is important for the vibrating screener users. If can influence the working life of vibratory screen and the quality of final products. So the installation and debugging played an important role in course of vibrating screen operation. So today we will talk about the vibrating screen installation and debugging in order to make the user know more about the vibrating screener working.

1) Pre-installation preparation

The new equipment, vibrating screen prior to installation, should be carefully scrutinized. As the manufacture of finished goods inventory piling up a longer time, such as rusted bearings, seals, aging or damaged during handling and so on, faced with these problems need to be replaced new parts. Also, as exciter, and the factory for rust-proof, injection of anti-rust oil, formally put into operation before the replacement into lubricating oil.

Instructions should be read carefully before installation, make full preparations.

2) The installation

(1) installation of supporting or hanging device. Installation, to foundation leveling, and then supporting or hanging device in accordance with parts drawings and installation diagram sieves, in order to install the components. Spring-loaded before the end-tag should be the actual stiffness values matching.

(2) sieve box connected to the supporting or hanging device. Bottles and later, should be required to adjust the angle. For the hanging of the sieve, it should also adjust the screen angle and screen box spindle box level. The general level of first-degree horizontal adjustment to eliminate the screen box deflection. Levels after correction, and then adjust the vertical inclination of sieve box. Vibration isolation spring force should be uniform, which could force the situation by measuring the amount of spring compression to judge. General, two sets of feed-side of the compression spring to be the same two sets of springs discharging side should also be the case. Nesting side and feed side may be differences in the amount of spring compression.

(3) installation of electric motors and the triangle tape. Installation, leveling should be based on the motor, motor level of need for correction, two tape round the corresponding grooves of the center line should coincide, triangular tension dictate the appropriate tape.

(4) required to install and fixed-screen surface.

(5) Check the connection sieve components (such as the sieve plate, exciter, etc.) a fixed situation, screen should be uniform tension, in order to prevent the generation of local vibration. Check the transmission part of the lubrication conditions, the motor and control box wiring is correct, and the rotation transmission part of the hand to see whether it is normal operation.

(6) Check the entry sieve materials, discharge chute and the funnel at work the next screen whether a crash.

3) Commissioning

Screening machine installed, commissioning should be empty, the initial check installation quality, and make the necessary adjustments.

(1) shall not be less than the sieve empty commissioning time 8h. In this time, the observation of sieve quickly whether to initiate a smooth, vibration and stability of operation, no special noise amplitude by the amplitude to observe its compliance with licensing requirements.

(2) The sieve operation, the vibrating screen box should not result in yaw. In case of yaw, which may be due both sides of the spring height difference is too large, hanging rope pull uneven rotation axis is not horizontal or triangular tape too tight, should be adjusted accordingly.

(3) driving 4h, the bearing temperature is rising, and then remained stable. The maximum temperature does not exceed 75, temperature should not exceed 40.

(4) If abnormal noise or driving after a sharp increase in bearing temperature should be immediately shut down, check whether the rotation axis is a flexible and well lubricated and so on, until after the start troubleshooting.

(5) 2-4h after driving down to check whether there are loose connection parts, if there are loose, tighten until after the drive.

(6) 8h after the test if no failure, only the installation of project acceptance.

The ball mill noise control is to control the noise output of the ball mill in the process of crushing materials by the engineering measures and is also to control the spread and receive of the noise,which is in order to reach the required acoustical environment.

Strong vibration and noise will be produced when the ball mill crushes materials and the noise can be up to about 100 to 115 dB (A),which does great harm to the operation workers and the surrounding environment.

If you want to control this noise of ball mill, the selection and application of ball mill sound insulation is important.

The ball mill sound insulation enclosure though no typical heat source, but cans in the collision of Jane long-term friction also can produce certain quantity of heat, also need to ventilation cooling. So the top cover open a vents and matches the muffler. The lower end plate and cover between shaft have crack, lie between the subglottic also often open, don't have to put wind path. This kind of equipment is to heat, the natural ventilation cooling way is enough. The cover of the structure of ball mill for assembly type, the first ball mill around erection channel steel skeleton, and then it into pieces of the cover wall plate assembly in successive skeletons. The upper portion of the cover plate for tile form, all assembly method for bolt coupling fixed, so in the equipment can be easily removed when the overhaul the sound insulation cover.

For convenience of homework personnel, in the sound insulation cover body is equipped with 8 group published two groups and the sound insulation window. The group of five for personnel to enter the laryngeal mask for ball mill in related to the operation with, the upper two equipment maintenance special door and a note oil lubrication with little door. Except through the sound insulation window lighting outside, enclosure also equipped with lighting facilities. Since it is the local sound insulation cover, there is part of the equipment in the hood, there is a cover body and the original equipment, the combination of between. Cover board and equipment should be sealed tight between fixed position. The problem is turning parts of the body and cover with more difficult, the rotation axis to cross the ball mill sound insulation cover the board, shall keep a circle gap here. Aperture neither too big. To avoid missing voice sound insulation effect influence; But neither is too small, so as not to cover plate and contact friction between the axis.

Sound insulation cover wall the composition of the board from inner to outer is as follows: 3 RRN thick plate, 6 nm thick drain clear stone cotton lint damping layer, 10 (~ en thick rock wool sound-absorbing board, spun glass cloth and 1 mm thick, perforation rate 30% of the principal part of the perforation panel. Cover plate thickness of the total for 11 firm. In the ends of the cover because of the self-contained tank tube end of the gap between less than 100 ram, cover board and not allowed and rotation tank have a contact, and therefore the place between the cover thickness for five (krma. Close to the shaft of the site because operation requirements often remove cover board, so this part of the cover plate is 4 ding m thick panels, with handles, may at any time off. Provide brand products within: the ball mill, the rotary kiln, mineral processing equipment, the grate ball mill and super fine ball mill.

Noise control of ball mill is the most direct, the most effective, the most economic measure to reduce the sound source sound:' from the sound source control noise'. So reducing noise source noise is the development trend of the research on noise control of ball mill.
