Product Description:

Product Description:

The jaw crusher is widely used in mining, quarry, metallurgy, building, highway, railway, water conservancy and chemical industry ,etc.It is especially for crushing  relatively hard rock effectively. The processing granularity is less than 550 mm and compression strength is no more than 250 MPA .It is used for coarse coarse crushing and intermediate crushing  for all kinds of of mining and rock.

Main Product Features:

1.International manufacturing processes and the most high-end material manufacturing.

2.The movable jaw assembly of high-quality steel castings, precision machining, forging billet eccentric shaft machine with exceptional reliability, more durable.

3.The crushing chamber symmetrical "V" shaped structure, the actual width of the feed inlet and the nominal feed opening width consistent.

4.Equipped with a wedge block nesting population adjustment device, more than the old-fashioned gasket adjustment is simple, safe and fast.

5.The motor frame crusher rack integration installation, reducing the crusher installation space and installation costs.

Q:How to distinguish between cone crusher, standard, medium or short head?
Short head, medium-sized, standard cone crusher, its working principle and basic structure are the same, just that the shape of the broken cavity is different.
Q:How to adjust the discharge size of hammer crusher
According to the previous reform and upgrade of crusher, we have summed up the reason why the hammer crusher has a large particle, one is because of hammer head wear and the other is because the screen is broken. The head is an important component of hammer crusher, it has a direct contact with the material, if the material hardness is too large, the degree of wear of the hammer will be deeper, the hammer will be years of, friction materials, the serious wear, the hammer blow to the material will not work, leading to oversized material. In this case, we need to replace the hammer head of the lime hammer crusher in order to guarantee the normal work of the hammer crusher, ensure the uniformity of the particle size and ensure the qualified.
Q:What is the reason that jaw crusher does not cut material?
In view of this situation, you can try some of the following methods:A: can take pre screening, pre washing ore, ore blending control of water, but some ore is difficult to deal with;Two: can also be pre screened, and properly increase the ore discharge; increase discharge efficiency;Three: also can reduce the spindle speed, increase the discharge mouth;Four: you can also adjust the discharge port, but the angle is not peaceful;On the other hand, before using a crusher, it is necessary to find out what basic requirements the crusher uses for the material. On the jaw crusher, such as broken is due to sulfur; sulfur contained a lot of dirt, so the more the material mixture, and the temperature of the material is too large, will lead to large viscous material in the crushing process, thus causing a blockage of the stem broken before. Therefore, in this case, it is necessary to ensure the drying of the material before the broken material, and also to ensure the purity of the material, so that it does not contain too much mixture.
Q:Operation rules for hammer crusher
1, the inspection must be properly wear good labor protection products, careful and careful. 2, regular inspection of the hammer wear, observe whether the hammer crack, hammer joint vibration, and do the corresponding treatment and to the superior leadership. 3. The particle size of the crusher is not allowed to exceed the maximum particle size of the specified material. 4, pay attention to observe the operation of the crusher, check the hydraulic and lubrication system is normal, found unusual, timely and control in contact with, according to the situation to take corresponding measures, and timely report to the higher level leadership. 5, regularly check the drive belt and coupling protection cover, whether or not loose, anchor bolts are loose, or to timely fastening. 6, regular inspection of bearing temperature and sound, airframe vibration, abnormal, timely notify the relevant personnel for inspection.
Q:What are some common crushing methods for crusher?
Crush crushing, impact crushing, impact crushing, others are not known
Q:How many kilowatts is the crusher motor in the stone factory?
Stone crusher motor power in kilowatts to hundreds of watts range.The following factors should be considered in selecting the motor:1 、 provide the power supply for the motor, such as single-phase, three-phase, DC and so on2, the working environment of the motor, motor work place is special, such as humidity, high temperature, chemical corrosion, dust and so on
Q:What crusher is the counter hammer crusher? What's the difference? Is it all right?
Performance advantages:1., feed big mouth, broken cavity high, to adapt to high hardness of materials, large block, stone powder less2. material hanging, crushing power consumption is small3. new hammer head, great impact4. hammer shaft installation adjustable, hammer head long service life5., the size of the grid is adjustable, the product size is controllable, and the particle shape is good6., the chassis can be turned over, more convenient to overhaul7. square shank bolt, shock resistant and abrasion resistant8., compact structure, strong machine rigidity9., the body structure, easy to handle and install10., shock, counterattack, impact (stone stone) crushing function, the production efficiency is high, the wear of parts is small, comprehensive benefits significantly
Q:What is a dry hammer crusher? Who can tell me?
DSJ series drying hammer crusher can also be used in the cement industry, in the area of filter cake and environmental protection, drying and crushing treatment of carbide slag.
Q:Daily maintenance of ore crusher
Daily maintenance of mining crusher equipmentIn order to ensure the mine crusher equipment is in good technical condition, ready to be put into operation, reduce downtime, improve mine crusher intact rate and utilization rate, reduce mine crusher wear, prolong the service life of mine crusher, reduce mine crusher operation and maintenance costs, and ensure the safety in production, we must strengthen the daily maintenance the work of mine crusher; do regular maintenance, force, correctly handle the use of maintenance and repair, do not allow only do not keep, just don't keep.
Q:How to choose the proper cone crusher
According to the quality and credibility; customers can not blindly listen to advertising, you can consult the production line of operations and technical staff. These people through their own work, you can clearly understand what brand models of cone crusher, good quality. Some parts are easy to wear and often replaced. The life cycle is also an important part.
