Technical advantages of jaw crusher in stone crushing

Jaw Crusher is one of the most widely used crushing machines in mining industry. It is a stone crusher with the advantages of simple structure, stable performance, easy maintenance, final particle and high crushing ratio. Jaw Crusher (also called Jaw breaker) has been widely applied in mining, metallurgical, construction, road and railway building, water conservancy and chemistry etc. The stone jaw crusher is mainly applied in the primary crushing in which the compressive strength of original material is under 320Mpa.

With the obvious advantages, such as big reduction ratio, equal product granularity, simple structure, reliable working condition, convenient repair and economical operation, Hongxing jaw crusher is widely used in the works of mine, smelting, building material, road, railway, irrigation, chemical industry, etc. Now, through the analysis of the working principle and components of Hongxing jaw crusher, we will explore the superiorities of jaw crusher in stone crushing. As we all know, whatever you do efficiency is required by any boss or leader. And also the mining machinery you use is required high efficiency. Henan Hongxing Mining Machinery Co., Ltd. is one of the most famous jaw crusher manufacturers and suppliers in China.

The jaw crusher is mainly composed of the frame, eccentric shaft, big pulley, flywheel, moving jaw, side guard plate, toggle plate, toggle plate back seat, adjust gap screw, reset spring, fixed jaw plate and movable jaw. The motor driven belt and pulley do the up and down movement through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the moving jaw becomes larger, thus pulling the movable jaw plate move to the fixed jaw plate. At the same time, the material is squeezed, rubbed and grinded. Notes: the brackets also play the role as insurance. Usually, we improve the producing efficiency of jaw crusher from the following technological superiorities.

1). The jaw crusher crushing materials mainly depends on the squeezing force between the fixed jaw and the movable jaw. Both the fixed jaw and the movable jaw are composed of the jaw bed and jaw plate. The jaw plate is fixed on the jaw bed through the bolt and the drift, which are the main wearing parts of jaw crusher.

2). The jaw bed of fixed jaw is the frame front wall of jaw crusher and the jaw bed of movable jaw is hanging on the side of the jaw crusher, which needs sufficient strength and stiffness to suffer the crushing reaction force. Therefore, most of the jaw bed is made of iron castings or steel castings.

3). The rack of jaw crusher is used for supporting the eccentric shaft and suffering the crushing reaction force, which needs enough strength and stiffness. Generally speaking, the rack of jaw crusher is cast by the whole steel castings, but the rack of large jaw crusher needs to be cast piecewise, and then be linked into a whole through the bolt. Therefore, the casting process is complex.

As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior iron ore screening equipment, stone portable machine, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
