Applicability Analysis of Various Types of Mine Breaking Equipment

At present, common types of mining crusher jaw crusher, cone crusher, crusher crusher, impact crusher and hammer crusher, which impact crusher and hammer crusher are all impact crusher .

Crusher equipment to rely on mechanical energy to crush the material, according to different types of crusher works are different, crushing mechanical energy mode of action are squeezing, splitting, breaking, shearing, impact and blow. Due to the different ways and capabilities of the material, the nature of the material determines the choice of crushing stone equipment, the same broken machinery have different applicability. The following simple analysis jaw crusher, cone crusher and hammer crusher applicability.

Jaw crusher on the broken material is to rely on moving jaw swing on the material to complete the work, the work is intermittent, although the crushing ratio, but the force of the material is relatively slow. And more flake stone. Need to add supporting the shaping equipment to ensure the finished grain type.

Cone crusher is to rely on the eccentric movement of the cone of the material extrusion, shear, grinding to complete the job. Equipment crushing ratio, gravel particle shape is better, but in the production process produces more powder, in today's advocate of green mines today do not advocate the use of.

  Hammer crusher jaw crusher than the continuous work, and finished stone shape is better, low content of needle sheet. But the hammer crusher fatal shortcomings is the machine wear fast, especially the hammer and counterattack liner performance is particularly prominent. Therefore, more suitable for hammer crusher in the cement production line in the hardness of brittle materials such as limestone broken. And now improved after hammer crusher hammer material for the bimetal composite hammer, hammer former material for the chromium, impact resistance; body material for the fierce, wear-resistant. The greatest degree of extension of the accessories life. In particular, some hammer crusher in the form of dual-motor, large pieces of material into the crushing chamber when the motor instantaneous current, the material can be fully broken.

Heavy counter hammer crushing equipment working principle:

The heavy crusher III uses impact force to crush materials. Here is the crushing procedure: materials fed into the crusher are crushed by the force of high speed revolving hammer, these crushed materials got kinetic energy from the hammer rushing into the damper and diagrid, striking against one another at the same time. After multiple strikings, these materials smaller than the diagrids space will be expelled. Other larger ones will be struck, ground, squeezed once more by the hammer until the final required particles form.

Q:What is the advantage of a jaw crusher made of large and medium-sized plain pendulum?
Its disadvantages are: the structure is complex and relatively heavy; it is heavier than the same size crusher; 20%-30%; secondly, its moving trajectory is not ideal; the upper horizontal stroke is smaller and the lower horizontal stroke is larger.
Q:What are the specifications of gyratory crushers?
Gyratory crusher was first used in 1898. It is still widely used in concentrator and other industrial sectors because of its reliable operation and large production capacity. Its specifications are expressed by the width of the ore feeder and the width of the discharge gate. For example, 500/70 type gyratory crusher, its feed width is 500mm, and the discharge width is 75mm.
Q:The working characteristics of compound crusher
(1) the structure is simple and reasonable, and the running cost is low. The use of stone stone stone principle, small wear. (2) high crushing rate and energy saving.(3) it has fine crushing and coarse grinding function.(4) the water content of the material is little affected, and the moisture content can reach 8% or so.(5) more work noise is less than 75 decibels (DB level), dust pollution is less.(6) suitable for crushing medium, hard and hard materials.(7) the products are cubic, the density is large, and the iron pollution is very small.(8) impeller lining, small wear and easy maintenance.
Q:What is the crushing strength of Xuan Wuyan?
The counterattack crusher is divided into single rotor reverse breaker, double rotor reverse breaker and single segment hammer type anti cracking machine and compound shaping anti break.
Q:Ask for help, stone, I used a broken plug-in
Sand and stone should be used to repair roads. It is recommended that you use the PFL vertical hammer composite crusher, which can be used as stone for crushing and making sand, and for repairing expressways, this crusher is often used.
Q:Crusher construction scheme
Maintenance: cone crusher because of its bad environment, dust, and some use of unit maintenance is not in place, often appear all sorts of problems in the operation of general cone crusher in operation should pay attention to the following problems, in order to ensure the normal operation of the machine. When the cone is broken, the material should be uniform and not segregated. If the feeding inequality appears the decline of production capacity, product size is too large, the spring moves frequently, bowl bearing pressure, rising power consumption.
Q:What are the differences between cone crushers, PYZ, PYB, and PYD?
Cone crusher is mainly composed of frame, horizontal shaft, moving cone, balance wheel, eccentric sleeve, upper crushing wall (fixed cone), lower crushing wall (moving cone), hydraulic coupling, lubrication system and hydraulic system.
Q:What are the models of the crusher?
PE, PEX, VI, PCH, SMG, SMH, JC, PF. There should be something else. I only know the models
Q:Advantages and disadvantages of hammer crusher
Hammer crusher is the hammer and sieve wear quickly, and find the balance maintenance time is long, when crushing hard material, wear faster; crushing the wet material, clogging sieve seam, so easy to cause downtime (the material moisture content should not exceed 10%). Crush hard, hammer and lining wear, the consumption of metal materials, regular replacement of wear parts required for more maintenance time, broken in the wet material, bar blockage caused the decline of production capacity.
Q:What are the main structural differences between coarse crushing and medium crushing cone crushers?
The mechanical structure of the cone crusher is the two pyramids of the mountain: active cone (broken cone, also called internal cone) and fixed cone (also called external cone)
