Man is a curios animal. Human being has seen thousands of centuries and had evolved ever since. History is one of the most interesting branches of study. It tells us how we have come to our present state. But history without any evidence can very well be nothing but just a piece of fiction. One of the ways that validates history and its findings is through mining. Mining is not new to humankind. Since the beginning of civilization, man has used the metals and stones found closer to the surface of Earth for various purposes. As time and technology progressed, mining also became wider and more extensive.

Now we have top of the line machinery for mining that has made the work quite easy and much more productive. Now we know about the ancient civilizations more than ever. In addition, mining is mainly used for extraction of minerals, stones, rocks of various degrees of importance. From precious metals like gold and platinum to stones like diamond, rubies, sapphires etc. everything is obtained from mining. Not only precious stones and metals, mining gives us many metals and stones that are used in machinery and various industries. We obviously cannot visualize a world without metals.

Few of the materials that are obtained by mining are base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Rather any material that we cannot grow by agriculture or create in a laboratory or factory is usually mined. With the extensiveness in mining, there is obviously a whole industry dedicated to mining equipment and mining supplies.

There is a plethora of geology outfitters and field equipment that is used during the various mining processes. One of the basic requirements of good mining gear is the durability. As mining is always outdoor and can be in severe weather conditions, it is necessary that the mining gear used should be able to withstand all kinds of weather conditions. The sturdiness of the clothing material is of great importance and so is the high visibility. Even rest of the equipment needs to be weather proof and efficient.

Geological Surveying is the perfect destination if you are looking for geology outfitters and field equipment. They have the highest quality of products at the best of prices. The mining supplies at CGS Mule are made with superior quality materials that would never fail you and deliver the best.

Cement production line is to build cement clinker production line in mining areas, and build cement grinding station near large and medium-sized cities (i.e.Ore spiral classifier cement sales markets). Most cement mixed materials are industrial wastes produced in cities. A cement grinding station can greatly digest the slag, fly ash, cinder, coal gangue and other industrial wastes near cities, which is also a green and environmental industry. The cement grinding station supplied by our company has the advantages of the simplest process, the most convenient operation,Limestone dryer the fewest process equipments, less investment, less power consumption and so on.

During the whole cement production line, drying and powder-choosing is the most important steps!!! Dryer is the main cement mechanical equipment in the drying step. Here we mainly explain the grinding step. For this step, cement ball mill is the essential equipment.

A cement ball mill is mainly used in the grinding of finished products and raw materials, and also used in metallurgy, chemicaConcentrator table pricel, electric power etc...In addition, open flow grinding and close-circuit grinding with powder concentrator are available as well. Cement ball mill has the advantages of strong adaptability to materials, continuous production, big reduction ratio, simple fineness-adjusting and soCement rotating dryer on. It is capable of dry production and wet production, also can grind and dry at the same time. After drying, raw materials processed by cement mill will turn into raw cement. Then we are going to use an important product in cement machineryCement rotary kiln. As we all know, the cement processed by cement mill is raw, in other words, after water&rsCone crushersquo;s mixing, cement is still cement, and water is still water. Both of them cannot be mixed together. So here we make raw cement processed by cement rotary kiln, in order to get the cement of semi-finished products.

Why do we say its semi-finished? Because the cement processed by cement mill cannot turn 100% raw material into powder, we need to screen these semi-finished products and make those raw materials which still dont turn into powder return to the production line for processing.

So far, cement production line is running to the end. Of course, in the whole production line, the role of conveyor is indispensable. Whether raw materials enter into the dryer, and then the dryer enters into cement mill, or cement mill enters into cement rotary kiln, which both use the conveyor.

As we know, if a person is sick he needs to see a doctor in a hospital where someone will tell you what's wrong with you and make an analysis for you. Similarly, how to analyse the possible problems when a jaw crusher can not crush normally? Let's be a doctor.

While using the Jaw Crusher, there might be problems happening, despite we edged to avoid such kind of suitation. But there are many problems which can be fixed easily. Here is a solution for the problem: the flywheel rotates but the jaw crusher can not crush, the toggle plate falls down.

Possible reason 1

The spring at the back botttom of the jaw crusher break. We can solve this problem simply by replacing the broken spring with a good one.

Possible reason 2

The jaw bar is broken. Maybe while the jaw crusher working, something extremely hard has fallen into the crushing chamber. And the jaw crusher can not break it down(we kinly remind our users to avoid such accident in daily production, for it will do great damage to the machine). In this case, the jaw bar would very likely to be damaged. We need to put a new jaw bar into the right position before the crusher can work normally.

Possible reason 3

The jaw bar bolt is loose. Just fasten the bolt on end of the jaw bar would solve this problem.

Jaw crushers are equipments which can coarsely and intermediately crush several hard materials by the press and bend of the two Jaw plates. It consists of fixed and movable Jaw plates. When the both plates close to each other, the materials can be crushed, and when separate each other, the smaller materials than discharging open can be sent out on the bottom, the action of crushing is intermittent. The equipment is widely used in industries such as mining-selecting, construction materials, silicate and pottery, because of the advantages of simple structure, reliable operation, crushing hard materials.

Main engine suddenly stops.

The output can't reach original factory standard

Reasons:

1) The hardness or endurance of materials go beyond the range of instruction book

2) Electric motor connects inversely, the main engine works opposite (Jaw crusher rotates clockwise)or the electric's triangle connection is replaced by star connection by mistake.

3) Discharging open is smaller than specified limits

4) Jaw plate moved, the tops of the teeth opposite each other.

5) The voltage of working space is too low

6) Movable Jaw plate and bearing are wear off that the break is too large that the outer ring of bearing comes into relative rotation

Repairing methods

1) Replace crushing material or crush once again.

2) Adjust the motor connection

3) Adjust discharging open to adapt the instruction book and increase the machines used in tiny crushing

4) Check the distance between dental plate and pitch of gear, if not match the instruction book, replace the Jaw plate, adjusting the relative places between fixed and movable Jaw plates make sure that top of the tooth face the tooth root, then fixed in case the shift

5) Raising the voltage of working space to adapt the demand of main engine.

With the sharp rapid development , the construction of buildings need a lot of sand and also the sand are not the same quality requirements, artificial sand compared with natural sand, rough appearance and shape is the main difference. Look less rough and the shape of round, concrete pouring for the mobility when an adverse effect, this will cause poor mobility of concrete into the gap created, directly affecting the quality of the projects. Therefore, the advantages and disadvantages of artificial sand quality should be the main points of the rough in appearance and shape of the circular degree of the other, artificial sand production of raw materials, synthetic materials, there are other limitations must be caused by manufacturing industry and construction companies face serious on the issue.

Although the river sand in construction has very many advantages, but the dwindling resources of river sand, sand from the direction of the construction industry began to search for new sand source. With the building of the indicators require the improvement of the natural sand and natural weathering due to the geographical distribution of different generation conditions, and present physical and chemical indicators of volatility, which for the concrete, especially high-performance concrete is certainly not conducive to the stability of quality. In fact, can be resolved through artificial natural sand presence of these shortcomings. And because the decrease river sand, artificial sand in fact not only solved the problem of the shortage of natural sand, but also an important raw material of high quality concrete.

Coarse sand and rounded appearance of the poor degree of main production equipment from the mechanism determined by sand. From the perspective of industry associations, like the springing of artificial sand production, with the herd instinct of the phenomenon, many practitioners lack professional knowledge, coupled with some low-quality equipment manufacturers focus on profits, the market appeared a large number of poor and immature equipment, to the healthy development of artificial sand brought serious consequences. Therefore, any investment there are risks, artificial sand investment is no exception, investors need to note, in addition to market demand and prospects, but also need to be careful enough there in the expert consultation.First, we must know that sand production is the cost is high, and if that is simply crushed stone sand, in products for the technical indicators are not clear on its easy access, investors may have to be a heavy price.

The common processes for ore dressing include gravity separation, flotation separation, magnetic separation and electrical separation. The following text will elaborate on these four methods.

A. Gravity Separation

It is an industrial method of separating minerals by the difference of their relative density. Mineral particles of different density receive the hydrodynamic and various mechanical force in the moving medium like water, air and heavy liquid, causing proper loose strata and separation conditions, by which minerals of different density are separated.

B. Flotation Separation

According to the physical and chemical differences among minerals, they can cling on air bubbles selectively through flotation reagent’s disposal. The ore dressing of nonferrous metal like copper, lead, zinc, sulphur, molybdenum, etc. usually adopts this method.

C. Magnetic Separation

This method is based on the different mineral’s magnetic property. They are separated by the different acting force in the magnetic field of magnetic separator. It is mainly used in the separation of ferrous metal like iron, manganese, chromium, etc. It also can be adopted in the separation of nonferrous metal and rare mental.

D. Electrical Separation

Minerals are separated by the difference of mineral’s conductivity. When minerals are in the high-voltage electric field of electricslot, due to the different conductivity, minerals are separated by the different acting electrostatic force. At present, it is mainly used in the separation of mixed crude concentrate like the separation of scheelite and cassiterite, the concentration of zircon and tantalum-niobium ores, etc.

People need to bath to keep health, and similarly, machines also need a bath to keep clean and prolong its life. Taking cleaning jaw crusher parts as an example. There are mainly five cleaning methods of jaw crusher parts:

(1) Vibrative Cleaning: put parts on the cleaning basket or cleaning rack of vibrating cleaning, and immerse them in the cleaning solution. By the cleaning machine’s vibration that simulates artifical rinsing and washing movement, together with cleaning solution’s chemical effect, greasy dirt can be easily washed off.

(2) Scrubbing: put parts in a container with diesel oil, coal oil or other cleaning solution, wash them with cotton yarn or brush. This method is easy and simple, but unefficient, so it is suitable for single piece small parts. Generally, using gas is not allowd due to its lipid solubility, prone to causing healthy problems and fire accident.

(3) Spray-wash: spray cleaning solution with some pressure and temperature into the parts surface. This method is effcetive, but the equipment is a little bit complicated, so it is suitable for the simple structured parts with much oil dirt.

(4) Ultrasonic Cleaning: cleaning oil dirt by both cleaning solution and ultrasonic oscillation.

(5) Boiling Wash: put well-compounded solution and parts into an appropriate sized cleaning pool that is welded with steel plate. Heat it to the temperature of 80~90 ℃, and boil it for 3~5min.

Now in the market, the popular and agreed grinding machine include the ceramic ball mill, energy-saving ball mill and rod mill. The ball mill has the advantages of smaller size, even size and can apply to the grinding of the quartz and feldspar. The ball mill has bigger output size so it can avoid the damage by “over crushing”. So as the grinding machine, control the rotary speed is benefit.

Each machine, each type has its certain rotary speed when it was be designed. As all we known high speed will have high capacity. But control it to be some certain is very important. High speed, intensified campaign, also the raw material has its own energy, so the over crushing will be occurred in the grinding.

Taking ball mill as an example, Type 1224. As we all known that its rotary speed is 27-34 r/min, if we increase the speed to the 36 r/m, the capacity will be get by 4.2%. In this condition, Capacity of the size below 5mm will increase from 11% to 15%, and the metal will be 4% to 5.2%.

More knowledge, more news and more about the products come to Zhengzhou Honxing Mining Machinery Co., Ltd. which is a professional manufacturer and exporter in the mining equipment. We has strong technology, good products, and design the processing line according to the site and requirements and realize the concept of customer-first.

When we make sand, the third generation sand making machinery and the rod mill are main equipment, but we can also see the situation of the over-broken. Today, the exports in Hongxing will explain it to you.

Firstly, when the rock was sent into the rod mill, we should discharge it timely after broken. If it was grinded too long, it will be over-broken.

Secondly, the gap between the sticks are the way to protect the rock from being over- broken, if the gap between the sticks are too narrow, the sand will be over-broken.

Lastly, the compression strength of the rock is weaker than the stick. So the sand was easier to be over-Broken.

Crusher is used in mining industry in one of the most equipment, and now, with the rapid development of our country industrialization, used mining machinery and higher demand, so choose of high quality crusher becomes crucial!!!!!

Although China's crushing equipment development of very good, but in the development of our country, the crusher industry more than there will be some problems still, these problems can directly affect the development of the industry of our crusher, so what the problem really is plagued by the development of the industry of crusher.

China's crusher complete products from the auxiliary tool to product change only experience for twenty years, crusher industry was a young industry, but also a sunny industry. But because of that, many in the industry by private and into the mold enterprise as the main body, after 20 years of market beat up and not a part of the success of the enterprise, but a more is in business started, that is, in the period of capital accumulation and experience accumulation stages, it is difficult to attend a deeper level of considered and as. Although a lot of enterprise also have ten years, twenty years or even further to the enterprise development planning and the grand plan, but this kind of planning and the current situation of the mould enterprise in China and its own developing space don't match, so more stays in theory, it is difficult to really implementation.
