How to understand the model of jaw crusher

Jaw crusher, abbreviated as jaw crusher or tiger mouth, is a very important crushing equipment in the mining, smelting, building materials, highway, railway, water conservancy and chemical industries. The following is a specific interpretation of the jaw crusher model:

1、 Naming rules

The naming of jaw crushers usually follows certain rules, which help users quickly identify the type and performance characteristics of the equipment.

Coarse jaw crusher: Models of coarse jaw crusher are usually named in the form of “PE+number”, such as PE-600 × 900 (69 E crusher), PE-1500 × 1800, etc. These numbers usually represent the feed inlet size (width x length) of the crusher, indirectly reflecting the processing capacity of the equipment.

Fine jaw crusher: The models of Fine jaw crusher are named in the form of “PEX+number”, such as PEX-150 × 750, PEX-250 × 1200, etc. These numbers also represent the feed inlet size of the equipment, but the feed inlet size of the slender jaw is usually smaller and suitable for fine crushing operations on materials.

2、 Type and Characteristics

PE series: The PE series jaw crusher has been around for a long time due to its simple structure, reliable operation, easy maintenance and repair, and relatively low production and construction costs. It is still widely used in various industrial sectors until now. Among them, the 46, 57, and 69 jaw crushers of the PE series are relatively common small models. This series of equipment has many models and can meet the processing and production of various large, medium, and small stone materials.

PEX series: The PEX series fine jaw crusher is mainly used for fine crushing of materials and is a secondary crushing equipment. Its production capacity is between 8105t/h, and the discharge port adjustment range is 1890mm, which is finer than ordinary jaw crushers and particularly suitable for small and medium-sized crushing production lines.

HD German version: The HD German version of the jaw crusher is jointly developed with foreign countries, and its crushing chamber shape and motion parameters have been optimized to expand the product’s application range. In terms of handling hard materials, the HD German version of Jawbone has a good performance. Its low suspension motion mechanism design provides a larger crushing ratio, while using high wear-resistant toothed plates, which have longer maintenance cycles and save operating expenses.

CJ European version: The CJ series European version of the jawbone is developed and designed based on customer market needs, with significant improvements in many aspects. It adopts a non welded detachable frame, wedge type discharge port adjustment method, steel plate elbow plate, and oversized bearing design, which ensures that key components are not damaged and extends their service life.

3、 Performance parameters

The performance parameters of a jaw crusher mainly include production capacity, feed particle size, discharge particle size, motor power, etc. These parameters directly determine the crushing effect and scope of application of the equipment.

Production capacity: The production capacity of different models of jaw crushers varies, ranging from a few tons per hour to thousands of tons per hour. Users should make reasonable choices based on their production needs when making choices.

Feed particle size: Feed particle size refers to the maximum size of material that the equipment can handle. Different models of jaw crushers have different feed particle sizes, and users should choose according to their own material characteristics.

Discharge particle size: Discharge particle size refers to the particle size of the material after equipment crushing. Users can change the discharge particle size by adjusting the discharge port of the equipment to meet different production needs.

Motor power: Motor power is the power source for equipment operation, and the motor power varies for different models of jaw crushers. Users should make reasonable choices based on their production needs and power supply situation when making choices.

In summary, the interpretation of jaw crusher models requires comprehensive consideration of naming rules, types and characteristics, as well as performance parameters and other aspects. Users should make reasonable choices when selecting equipment based on their production needs and actual situation.
