Jaw crusher is one of the important machines in mining industry and it can cause dynamic pressure in various kinematic pairs. Jaw crusher has many incomparable advantages compared with other crushing machines, such as stable and reliable operation, long service life, loose structure, little powder dust, low noise, simple repair and maintenance and low electricity consumption. The parts such as connecting rod, movable jaw and kinematic pair will produce huge inertia force in the crushing process of this machine, and jaw plate of jaw crusher will sustain the starting pressure, for this reason, the expansion of the abrasion of the kinematic pairs of jaw crusher will influence the strength of the spare parts and reduce the production efficiency of the crushing equipment. The periodical change of the inertia force in size and direction of jaw crusher in the crushing process will cause the vibration of the machine and imbalanced rotation of the eccentric shaft.

To eliminate these influences on the crushing machine, when designing the machine, we need to get the changing order of barycentric velocity, acceleration and inertia force of the connecting rod and the movable jaw. The experts of Henan Hongxing Mining Machinery Co., Ltd. conducted simplified and simulation experiment on compound pendulum and simple pendulum jaw crusher in the measurement and calculation process. Compared with other types of crushing equipment, jaw crusher has bigger crushing ratio, wider application ranges, so that it is one of the indispensable crushing machines in all kinds of crushing and powder grinding production lines and it plays an important role in mine, building material and cement production industry and promotes the fast development of social industry.

The quality of jaw crusher is represented on its performance and the using cycle of the jaw plate. A jaw crusher with high quality can run stably for a long time and the time and frequency of stoppage and maintenance can be reduced, thus saving unnecessary production wastes and economic losses for the customers. Hongxing GFP jaw crusher is improved on the basis of traditional jaw crusher, and this kind of deep-cavity jaw crusher has the features of big production capacity and even granularity of the final products, and more importantly, it can run stably, so that it has wider application in mine, metallurgy, building material, construction and chemical industry.
