The demand for coal in China is still relatively strong and its price is rising, especially in winter when coal use is at its peak and coal mining plants are busy. The mined coal needs to be crushed before it can be applied, and large coal mines are generally crushed with jaw crushers, which are common coarse crushing equipment with a maximum feed opening of 1700mm and a large output range of 1-2200t/h. They are very effective in crushing materials of various hardnesses, so what are the models of jaw crushers for coal mines? Which one is good to use?
A. What are the models of jaw crusher for coal mine?
There are four types of jaw crushers for coal mines, including the basic PE jaw crusher, the German HD jaw crusher, the European CJ jaw crusher, and the new portable jaw crusher. There are different models under each type and their performance varies, as follows:
1. PE jaw crusher
Commonly used model: PE 500×750, PE 750×1060, PE 1200×1500
Capacity：1-1000t/h
Feeding granularity: ≤1200mm
Discharge size: 10-350mm
Performance characteristics: It is a traditional type jaw crusher with simple structure, reliable work, easy maintenance, wedge type discharge adjustment, uniform size of finished product.
2. German version HD jaw crusher
Commonly used models: HD86, HD98, HD125
Capacity: 50-750t/h
Feeding size: ≤900mm
Discharge size: 45-225mm
Performance characteristics: It is improved on the basic version of the jaw crusher, the crushing cavity type and movement parameters are optimized, the application range is wider, the use of oversized bearings and forged spindle, the bearing crushing force is greater, while the use of high wear-resistant tooth plate, longer maintenance cycle, saving production costs
3. European version CJ jaw crusher
Commonly used models: CJ96, CJ125, CJ1515
Capacity: 105-1160t/h
Feeding granularity: ≤1200mm
Discharge granularity: 60-300mm
Performance characteristics: This is a new type of coal mine jaw crusher, with non-welded disassembled frame, optimized movement parameters, larger crushing ratio, wedge-type discharge opening adjustment method, reducing the labor intensity of workers and downtime, so that the steel plate elbow plate, key parts are not damaged, oversized bearing design, integrated structure of the overall steel frame base, motor seat and mainframe.
4. New Movable Jaw Crusher
Based on the traditional jaw crusher, a movable carriage is added, together with feeding, conveying and electric control system, forming a movable production line, which can be divided into tire type and crawler type, driving directly to the site and operating after simple installation, convenient and fast, saving labor and economic costs.
B. What kind of jaw crusher for coal mine is good to use?
What kind of jaw crusher is good for coal mining? In fact, the above-mentioned four types of equipment are the ones that customers choose more often. If we look at this aspect alone, the more advanced the equipment is, the better it is, such as CJ European jaw crusher and mobile jaw crusher, but we should consider our own needs and investment budget when purchasing equipment. We can meet our own needs on the line.
The selection of equipment is one hand, the choice of high-quality equipment and a reliable manufacturer is more important, the general coal production enterprises on the jaw crusher capacity, quality, maintenance and other comprehensive performance requirements are relatively high, the long-term use of cost and benefit of more consideration, high-quality coal mine jaw crusher in crushing efficiency, yield, cost control better performance, to create greater revenue for the enterprise, so we should carefully compare when buying and selling, choose reliable quality, affordable cost-effective equipment!
