The jaw crusher relies on mechanical linkage movement to realize periodic squeezing and breaking of stones. Its core mechanical principle is eccentric shaft driving swing crushing, which is the most fundamental crushing mechanism for hard rock processing.
1. Core Power Transmission Principle
The motor drives the eccentric shaft to rotate at a fixed speed. The rotational motion of the eccentric shaft is converted into vertical and horizontal swing displacement of the movable jaw. This mechanical conversion transforms continuous rotary power into periodic reciprocating crushing power.
2. Moving Jaw Swing Crushing Logic
When the moving jaw swings toward the fixed jaw, the material inside the crushing cavity is squeezed, bent and sheared to complete primary fragmentation. When the movable jaw swings away, the broken materials fall down by gravity to complete discharging and material replenishing. This cycle repeats continuously to achieve batch stone crushing.
3. Toggle Plate Force Balancing Mechanism
The toggle plate is not only a force transmission part but also a mechanical safety structure. It bears the reaction force generated during crushing, balances the unilateral stress of the movable jaw, and keeps the whole frame stable under high-load impact.
4. Cavity Layered Crushing Principle
The crushing cavity presents an upper-large and lower-small trapezoidal structure. Materials receive layered squeezing from top to bottom. Large stones are crushed in the upper cavity, and small particles are refined in the lower cavity, realizing progressive particle size reduction.

The user purchased two sets of sand production line, each set of equipment includes ZSW490*110 vibrating feeder, PE750*1060 jaw crusher, HST250 single-cylinder cone crusher, JYS1238 sand making machine, YK2460 vibrating screen, 3016 sand washer and so on.
The designed capacity of this sand making project is 200t/h, and the equipment used includes 490*110 vibrating feeder, PE750*1060 jaw crusher, PF1315 impact crusher, 9928 sand making machine, two sets of 2460 vibrating screen, two sets of 920 single screw sand washer, two sets of XSD2816 sand washer, two sets of dewatering screen, and several belt conveyors.
Project configuration: Jaw Crusher PE900*1200, Cone Crusher HST315T, Vertical Shaft Impact Crusher VSI6X1263, Heavy Duty Vibrating Screen 2YKZ3080/3YKZ3080, Vibrating Feeder ZG1220Z/ZSW1360, Twin Screw Sand Washer 2XL1120, Bar Vibrating Feeder ZSW1360B, Bucket Wheel Sand Washing Machine DS4024, dewatering screen TS2450 many types of equipment. They will work together with the whole production line to crush and process the sand trap cobbles and mountain ores into natural sand, mechanism sand, and uniform material.
The finished products of the project are used for high-speed railway construction and neighbouring construction materials, which will strongly promote the local economic development. In the future, Jianye Heavy Industry Company will continue to give full play to its years of practical experience in the sand and gravel aggregate, construction waste resource reuse, industrial powder making, silica sand and other industries, as well as EPC one-stop turnkey services, to cooperate with customers and jointly promote the high-quality, healthy and sustainable development of the sand and gravel industry.
Jiangsu Rugao Calcium Powder Factory purchased two sets of Jianye 4121 high-pressure mills for the production of heavy calcium powder, which is mainly used in the filler industry and coating industry, and now it also maintains a close cooperation relationship with Jianye, and every year Jianye sends technicians or sales managers to visit the user.
The user uses calcined petroleum coke to grind and make powder, and the finished coke powder is mainly used for processing graphite electrodes. In recent years, the price of coke powder rises, the user spends tens of millions of dollars to build a production line with an annual output of 60,000-100,000 tonnes of high-quality coke powder, which is the first phase of the project, using two sets of 6R4528 high-pressure grinding mills of Jianye Company.
