Coarse Crusher is applied as supporting equipment, before fine crushing process in such trade as pharmaceutical, chemical and foodstuff etc., the crusher has better crushing effect for any material without limitation on its viscosity, hardness, softness and fiber etc... This crusher is of vertical crushing structure, and the material is fed into the crushing chamber through a hopper, crushed by simultaneous cutting of both fixed and movable knives and rotating impact of rotating knife, and flows to the exit automatically under the effect of rotating centrifugal force.

Broken equipment must be chosen to give the compound into the largest block of material, therefore, to the mine mouth crusher maximum width should be 1.2 times the size of the block material.

Design of large and medium-sized concentrator, in determining selection of jaw crusher or a gyratory crusher before use, generally from the installation of power equipment, weight equipment, infrastructure investment, production and management, equipment configuration and process operation of the pros and cons After a technical and economic aspects of comparison, to select the best.

Design, small concentrator, in order to adapt to the mining site to a large degree the characteristics of ore blocks, ore block sizes need to adopt and adapt the coarse crusher.

Located in the mining pit in the choice of coarse crushing machine, crushing function should be considered a special lifting the disintegration of the underground crusher(mining crusher for sale). Surface mining site located in the semi-mobile crusher can be used or mobile crusher.

Jaw crusher's advantages are: simple structure, light weight, relatively inexpensive, easy maintenance and transportation, exterior height is small, need to plant height is small, the workmanship, reliable, easy to adjust the port of discharge, crushing wet ore and when with clay minerals more easily blocked. Disadvantages are: lining wear, low treatment than gyratory crusher, crusher product size uniform. Too large for a long time, request to mine even need to set up equipment to the mine. In recent years, many domestic manufacturers to develop and produce a series of new large crushing ratio Jaw Crusher, so performance is greatly improved.

Every business organization wants to attain an optimum production at minimum fixed and operating cost. The quality and efficiency of machineries is entrusted with the task of realizing this objective. A sand mill is a piece of industrial equipment designed to grind a given material into very small particles of roughly equal size. Sand mills are used for processing a wide variety of products, and can also be used as mixers and dispersants, creating a uniform mixture of several components during the grinding process. A number of companies produce sand mills for various applications, including different designs and sizes to meet the needs of various applications.

Talking about a sand mill, a central bar agitates the sand, causing it to have a grinding action. Many sand mills produce very small particles on the first pass, with the particles passing through a mesh screen. Others have recapture systems, allowing people to pass the mixture through the sand mill again to make it finer and more even. The design works by agitating the sand, rather than creating pressure, ensuring that the grinding medium does not break apart in the device when it is used properly.

As the name implies, sands can be used as grinding media, but other materials may be used as well. The choice of medium depends on the material being ground. Some companies maintain several mills dedicated for specific uses, while others may change media as needed in a single sand mill. Sand mills are used in cosmetics manufacturing, the production of paints and pigments, and similar activities.

In the case of mixtures, sand mills can be used to run a mixture of components through for processing into a uniform paste or powder. This is widely applied in the production of paints, where pigments need to be ground with stabilizers and other components before being blended with a base. As the ingredients pass through the sand mill, they become thoroughly mixed. The very fine grind offered by this device allows for highly stable mixes without patches and chunks of various materials.

We follow strict quality management procedures at every level of our process to ensure flawless production from every stage. The plants and machines including resin manufacturing plants manufactured by us are based on proven technologies presently serving successfully to both the domestic and overseas clients.

'1025' period, China's economy will be strong up the development of construction machinery industry continued to provide important impetus to benefit from this, combined with business innovation and competitiveness on the rise, China's construction machinery industry will continue to remain high run. Expected in 2017, China's construction machinery industry will achieve 17 percent revenue growth, exports will increase by 25%, the export industry will be fully restored to the level before the international financial crisis. Expected to 'second Five', China's construction machinery sales will reach 900 billion yuan, exports will exceed $ 26 billion. With the speed, mining machinery industry will make greater progress, jaw crusher, impact crusher, ball mill, Raymond mill all have bright markets.

Experts believe that the impact on demand for construction machinery industry has three major policy force.

Out of the 'three rural' development, energy conservation, and many other considerations, experts predict the next 10 years China's infrastructure investment in fixed assets will focus on rail, road transfer to the water conservancy construction.

January-April 2011 the fixed assets investment up 25.4%, which in April invested 291.151 billion yuan in fixed assets, an increase of 1.42%, changing the fixed asset investment growth slowdown, mainly in the tertiary industry increased by 26. 50% of road traffic in April increased by 23.60%, with further investment in water conservancy construction, but also bring new demand for construction machinery.

February 2011, the Department of Housing and Urban-Rural Development and the provinces, autonomous regions, municipalities and separately listed cities signed the 'affordable housing target of responsibility', to be completed this year, 10 million units of affordable housing construction tasks. According to the Ministry of Housing and Urban data, in 2010 the construction of affordable housing projects reached 5.8 million units, investment of more than 800 billion yuan. In 2011 the construction of affordable housing projects 10 million units, the new investment of more than 600 billion yuan. This calculation, the 2017 investment or affordable housing projects will reach 1.4 trillion yuan.

Although China's construction machinery business all these years has made great progress, but whether it is in the level of technology, technological innovation and product-level and advanced foreign enterprises there is still a gap. In addition, we must clearly recognize that the key parts of construction machinery industry controlled by others, elements of the enterprise costs continue to rise, the order of competition within the industry is not standardized, will have a negative impact of construction machinery industry needs to accelerate the development and improvement. As to mining machinery industry, there are the bright future for stone crushers, belt conveyors, energy-saving cone ball mill, cone crusher, flotation machines and so on.

In urban construction and social development and the premise, whether or mining machinery construction machinery, countries have put forward a new concept of energy conservation, such as mining equipment Raymond, crusher, sand making machine, crushing machine, milling machines and other large industrial facilities must respond to the country's new energy strategy thinking.

Confirmed by practice, complete reliance on energy saving is only responsible for corporate social obligations voluntarily is unreliable. Since the year, China's energy strategy is energy source, energy saving as the first, energy is always visible on the main seat. Confirmed by practice, complete reliance on energy saving is only responsible for corporate social obligations voluntarily is unreliable. Year, China's energy strategy is 'open source energy', energy saving as the first, visible energy has always been on the main seat. Emission reduction project has strong social benefits, but in opening up the pre-investment, current economic uncertainty.

Lifetime risk of international investment experience will clarify and support the implementation of energy saving and emission reduction targets, if necessary, government financial intervention. In energy saving and emission reduction, China's Government had always followed the form of planned economy, to promote enterprise by administrative orders to start saving and emission reduction. With the transformation to a market economy, changes in the functions of government finances has led in recent years, effective on the government's preferential policies for energy saving less and less, saving on future energy infrastructure and technological transformation project loans have been abolished. Emission reduction necessary governmental, business and own a total of three hard. Immediate problem is that excessive dependence on government, business and join their own lack of social capital in general has not made use of. Energy conservation has become a unilateral action and obligations of the government, barriers to its progression.

In today's construction machinery and mining machinery development environment, companies must be able to find from the equipment itself, reducing costs and lay the two energy saving measures in the correct path of development can continue to lead the industry on the cutting edge.

In physics, the charge of a volume is commonly described by a quantity called the charge density or the charge distribution. When the electric field that arises from the charge distribution exhibits a volumetric symmetry, a handy relationship known as Gauss's Law may be used to calculate the charge distribution of the volume.

The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary, the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge. The percentage loading or change volume can then be read off the graph in Figure 3 or can be approximated from the following equation:

% loading = 113 – 126 H/ D

where H is distance from top of mill inside of lining to top of charge and D is diameter of mill.

Maximum power is drawn by a mill when the charge occupies approximately 50% by volume. However, as seen in Figure 4, the power curve becomes very flat in the range above 45%. As a result, mills are seldom run with charge levels greater than 45%.

In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater than if the mill had been “ground out” prior to shutdown. Because of this, rod mills are normally operated with a 32 to 40 percent charge by volume. In operation, this becomes a 40 to 50 percent charge, with a bulk density considerably lower than that of stacked rods.

Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered, it is recommended that ball mills be ground out prior to shutdown for measurement of the charge level.

Digging equipments for construction is a very strong and durable one. They are usually made of steel which can carry heavy materials without breaking and dig to the ground with the use of the excavator bucket teeth. This part of the machine is built like this so that it will break down the materials that it will dig and it would be easier for the machine to do its task because of this feature. As a result also, it is easier for the bucket to dig through the earth and scoop it up for easy loading and unloading.

Excavation is part of a construction project that requires heavy equipment machinery specifically an excavator bucket. It is an attachment that is very useful in construction projects that requires a lot of digging like in making bridges, trenches, ditches and also in mining. The bucket is an application that can be attached even at cranes, tractors, and other construction machinery. As the word itself, its main purpose is to dig and load a larger volume of material that is of great help and at the same time convenient to the workers at mining and construction sites.

The excavator bucket suppliers have designed this very efficient machine for a lot of purposes. In the construction area, it is used to break the soil and remove it for the purpose of making trenches, ditches or bridges. Aside from the soil, it can dig through any materials that are within its capacity. In landscaping, it generally is used to excavate the earth so that the area will be designed according to the plans. Moreover, it is used for mining wherein it clears the ground for different mining tasks. In addition it can even dig to the ground to gather raw materials like ore and rocks.

Operation of the excavator bucket requires you to be responsible of maintaining it in good shape. Like other machines, it must be checked for any damage and parts that needs to be fixed for it to work well in the area. You must be responsible in keeping it functional and efficient for you to accomplish your work according to your plans.

The excavator parts all work together in order to appropriately perform its task. The bucket has a point of attachment wherein it is designed to move and be maneuvered easily according to the wishes of the operator. The tasks and the area that the machine will be used will determine its size. Large and heavy equipment ones are more preferable if you are going to use it on larger projects. Moreover, a compact or smaller in size construction machinery is recommended for small areas and not so big projects.

The excavator bucket is indeed very useful in different areas especially that it is a very durable and powerful equipment in digging up materials based on its capacity. It serves a lot of purposes to workers and contractors. Maintenance is also easier if you do daily checkups and inspection on the equipment daily before you proceed with your tasks.

Strengthen reliable performance

Even open coal mine stripping operations are easily collapse, it put forward higher request to the materials of mining machine, in case of dangerous accidents the driver’s safety can be guaranteed. It should be taken into consideration in the machine functions, such as it can be equipped with a similar small hammer to the bus which can be used to break glass in dangerous conditions. In addition, mine mining machinery products closure and escape performance should be improved.

To distinguish whether the large-scale mining machine crash to other vehicles, changing the mechanical cab is necessary, it can help to reduce the blind range of the driver and will help improve the mining construction safety.

At present, in large mining, small cars must insert a red flag to prevent rolled by large mining equipments. The blind range of some large mining equipments can reach 30 meters, small vehicle drivers must be careful, especially in the pass avoiding to close to large-scale mining equipments.

A remarkable characteristic of mine construction is its danger, even in the smooth road. How to ensure the safety of mining construction, mining machinery, and development is an important direction of the product.

Focusing on energy conservation and environmental protection

Mining machinery products are generally in high intensity work environment, many products are in non-stop mode of operation except during product maintenance time every day. Running more than 20 hours on boot operation is a test for the performance of the product. A customer once said, some manufacturer promise him that the product can be used for six years, however, in a mining field, three years is the maximal utilization period. Customer’s request for the product is reliable, the product can to maximize efficiencies in the shortest possible time. For mine which highly dependent on equipment performance of construction environment, product reliability is an important aspect of mine head attention.

To improve safety performance

Mining area is not worry about the number of devices, and in many mines, we can see in the soil to dump truck loaded excavator, often have several cars in the queue which makes the vehicle without full capacity, it causes the waste of resources.

In the mine internal construction, dump truck is one of the largest usage product. Since last year, some Chinese companies marched into mine dump truck field, mining transport equipments as big main development direction are more obvious. It is likely that in several years later, equipments below 30 tons capacity will not be permitted to enter mining construction site.' Chairman of Inner Mongolia ZhunGeErQi kun gold machinery engineering Co., LTD Yu Guojin said. Creating more economic construction in a short period of time is the focus of mine construction . The products are made to improve work efficiency. Users calculation of the economic benefit of mining machinery products is important, the most careful 'durable ' is always the first requirements. In a recent period of time, the reporter has been to Inner Mongolia, Qinghai's to investigate, they discover customer’s need of the product has a very distinctive characteristic.

In the procsss of sand making production, sand maker and sand washer are all used very often. Sand wahser (or Sand washing machine) is widely applied to gravel pits, mining, building materials, transportation, chemical industry, water conservancy and hydroelectric power, concrete mixing plant and is used for washing, grading and dehydration of materials. Sand washing machine is classified into spiral sand washing machine and wheeled sand washing machine according to its structure and working principle. Next, we just list two common types of sand washer to introduce its working principle and characteristics.

Wheeled sand washing machine, with a novel sealing structure and reliable transmission device, has a reasonable structure, large capacity, low consumption, high cleanliness and little loss of the sand during the washing process. Working principle of wheeled sand washing machine: when wheeled sand washing machine works, the electric motor runs slowly with the impeller after being decelerated by the V-belt, decelerator and gears. The sand-stone flows from feed tank into washing tank, rolls with the impellor and grinds each other to remove the impurities on the surface of sand-stone. At the same time, add more water, the strong water flow will take away impurities and some low-weight foreign matters from overflow washing tank, then sand-stone becomes clean. The clean sand-stone is lifted up by vane to out-feed tank to finish the washing task.

Spiral sand washing machine has distinctive characteristics of simple structure, smooth operation, clean washing, high output etc. It is widely used in construction sites, gravel pits, glass factory, power plant and electrical ground. Working principle of spiral sand washing machine: spiral sand washing machine is used to clean soil by the promotion function of helical blades. Compared with wheel washing sand machine, spiral sand washing machine has higher cleanliness and better stone-cleaning effect.
