The motor of industrial jaw crusher machine drives the belt wheel. And makes movable jaw up and down by eccentric shaft. When the movable jaw down, the angle between the fixed jaw and movable jaw gets smaller, and the materials can be crushed to reach the crushing target. When the movable jaw rises, it leaves the fixed jaw plate under the function of drawbar and spring, then the crushed materials are discharged from the lower outlet of crushing cavity.

Jaw Crusher PE-500×750
Jaw Crusher PE-500×750:
The Jaw Crusher PE-500×750 is used in mining, metallurgy, construction, highway, railway, irrigation and chemical industries, and our jaw crushers have the features of high reduction ratio, even powder sizes, low power consumption and easy maintenance. The crushing strength of the jaw crusher materials is up to 350 Mpa.
Feature Of Jaw Crusher PE-500×750:
1) High reliability
2) Flexible capacity
3) Over-loading protection
4) Easy replacement of wear and spare parts
5) Long service time
6) High efficiency
Jaw Crusher PE-500×750 Operating principle:
The jaw crusher uses motor as its power. Through the motor’s wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
Working Principle of Jaw Crusher PE-500×750:
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.

Jaw Crusher, Stone Crusher, Rock Crusher
Jaw Crusher, Stone Crusher, Rock Crusher:
Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the
largest compression resistance of the material to be crushed is 320MPa. The jaw
crusher is widely used in mining, metall-urgical industry, building material,
highway, railway, and chemical industry.
Working Principle of Jaw Crusher:
The motor transmits power through belt, drives the moving jaw do periodic motion
to the fixed jaw surround the eccentric shaft. The angle between toggle plate
and moving jaw increases when moving jaw moves up. So the moving jaw closes to
the fixed jaw. The stuff will be crushed in this process. The angle of Jaw
Crusher between toggle plate and moving jaw decreases when moving jaw moves
down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of
rod and spring, the products after crushing will be discharged from the outlet
of Jaw Crusher.
Characteristics of Jaw Crusher:
High ratio of crushing, homogeneous final grain size, simple structure, reliable
working condition, easy maintenance, low operating cost.

Ore crushing and grinding
Ore crushing and grinding of the pre-sorting operation. A prerequisite for mineral processing is to make a useful mineral ores reached monomer separation. Monomer due to the existence of useful minerals to the grain size is very small, and sometimes need to ground the ore to less than 0.074 millimeters of 80% fineness, and even more would have to make a useful mineral to reach the monomer separation. From the stope ore block out a large degree, such as open-pit mining for ore block up to 1000 mm, it is up to 1000 mm to the mine to only a few dozen pieces of broken-micron (1 micron = 1 / 1000 mm) of fine-grained, often in several stages to complete. To fragmentation, in the large-scale processing plant generally coarse, medium and small three broken (there are four sections of the used), so that pieces of ore particle size gradually reduced to about 8-25 mm, and then grinding machine to grind . Useful until the mineral grains separated from the monomer to achieve so far.
Grinding is usually a section or two. Crushing and grinding broadly divided into the segments shown in Table 2-2.
It should be noted that Table 2-2 in the crushing and grinding a few paragraphs of the division is relative, it works with the size of the election, the use of crushing and grinding equipment type specifications, the product fineness requirements and other conditions.
Crushing and Grinding division of the number of outstanding paragraphs 2-2
Paragraph do not

Coarse grinding 25-5 1-0.3
Fine 1-0.3 0.1-0.074
At present, the ore crushing and grinding of the method is mainly through the role of institutional power, the more common mechanical force to the following five.
A, crushing a two broken face when approaching the squeezing pressure on the broken material. Jaw crusher, roll crusher, cone crusher is the main way to crushing the broken machinery.
B, cleavage is the use of sharp broken tooth wedging materials to the split power broken, the role of centralized power, the occurrence of local fracture in the brittle material to adapt to the broken.
C, the fracture of materials in the inter-face as bear fragmentation concentrated load of two-point (or fulcrum) beam, so that material itself broken folding flexor surface.
D, two broken face peel grinding materials made in the relative motion, shear stress imposed on the material so that the breakdown of materials occurred. This power is suitable for fine grinding of materials.
E, crushing it is to use impact of the broken ore. Impact is instantaneous force acting on the ore. Such as counter-attack crusher crusher impact force is.
Plant used in crushing, grinding often broken at the same time the way some of these combined effects.
Cone crusher,Cone Crusher Works
Cone crusher working principle of the crusher and the same cycle, but only in minor operations broken or broken machinery. In nesting chronology operations of the general uniformity of particle size than the coarse pieces of the high operational requirements, and so in the lower part of the crushing chamber shall be provided in parallel for some areas, at the same time, but also to speed up the cycle of the cone crusher speed, so that materials in the parallel region squeezed by more than once.
Minor operation in comparison coarse broken pieces of the big operation, so the loose after breaking a greater increase in volume. In order to prevent broken cavity may give rise to obstruction, the increase in non-nesting population to ensure that the required size of the nesting of the premise, must be broken by increasing the diameter of the bottom cone to increase the total cross-section of the nesting.
Cone crusher nesting population of small, mixed to the material objects of non-fragmentation result in more accidents, and because of, the fine particle size nesting operation of demanding to be timely in lining wear adjustment after the nesting population, which cone crusher adjustment device of insurance and operating more than necessary to rough broken.
Simon-style spring cone crusher overload insurance, the conical compression spring to force the shell to increase their own in order to increase the nesting population, from non-broken material. Nesting population by adjusting the adjustment to kit, containing solid rotation of the adjustment of housing units can use the thread on its outer shell in order to boost the increase or decrease to change the size of nesting population. Hydraulic cone crusher adjustment of insurance and with hydraulic crusher the same cycle
