European Type Jaw Crusher

The European Type Jaw Crusher is commonly used in primary or secondary crushing of mining materials. The European type jaw crusher is an advanced equipment developed for crushing stone materials used in construction projects such as highways, railways, and airport runways. The European type jaw crusher adopts the most advanced international crushing technology and manufacturing level, and is the first choice for efficient products when crushing hard and highly abrasive materials. The stone materials used in engineering projects such as highways, railways, and airport runways are mostly hard rocks such as basalt, with specifications ranging from 3 to 7 centimeters. The hardness of the crushed materials is relatively high, and generally, the yield of jawbone is low and it is easy to wear.

Structural Principles:

The European type jaw crusher mainly includes a base, a fixed jaw, a moving jaw, and an eccentric shaft. The fixed jaw is fixed with a fixed jaw tooth plate, and the moving jaw tooth plate is fixed on the moving jaw through a connecting bolt rod. There are side guard plates on both sides of the moving and fixed jaw tooth plates, and the upper end of the moving jaw is sleeved on the eccentric shaft. There is a bearing chamber between the moving jaw and the eccentric shaft, and the top of the moving jaw tooth plate is about 80-250mm higher than the fixed jaw tooth plate. The structure is simple and reasonable, and the raised movable jaw tooth plate has a good protective effect on the movable jaw and bearing chamber, while ensuring smooth feeding and avoiding material blockage and jamming. It is safe and reliable, and the utility model also simplifies the production of the movable jaw. The movable jaw bearing chamber has good sealing performance, good operating performance, no oil leakage, and improves the overall use of the machine. The noise is low, the operation is stable, and the energy-saving effect is obvious, which is conducive to promotion and application. It is widely used in mines In the fields of building materials, silicates, metallurgy, road construction, chemical industrial raw materials, etc., it is particularly suitable for crushing medium hardness materials, such as rocks, ores, clinker from cement plants, etc.
