Jaw crusher is one of the most widely used equipment in crushing and milling industry. Fodamon engineer will reveal the pioneer of grinding process – jaw crusher from the aspects of mainstream products in the market, their respective advantages and disadvantages.
In 1858, the simple pendulum crusher was invented. So far, the jaw crusher has a history of more than 150 years.
China began to imitate the production of compound pendulum jaw crusher in the early 1950s. In order to improve the performance and work efficiency of jaw crusher, various special-shaped jaw crushers have been developed at home and abroad, but the traditional compound pendulum jaw crusher has finally been widely used.
Jaw crusher is widely used in many fields such as mining, smelting, building materials, highway, railway, water conservancy and chemical industry. It is in the position of “the first knife” in the complex crushing process. It is mainly divided into six parts: frame, transmission part (motor, flywheel, pulley and eccentric shaft) and crushing part (jaw bed, movable jaw plate, fixed jaw plate), safety device (elbow plate, spring pull rod part), adjustment part, centralized lubrication device.
In order to improve the crushing efficiency of jaw crusher, the R & D and improvement of jaw crusher have never stopped at home and abroad. After more than 60 years of improvement and technology introduction, the mainstream jaw crusher in the domestic market includes PE, Pew and jaw crusher (integration of motor and crusher, hereinafter referred to as integrated crusher) and other products.

Among the above three series of jaw crushers, PE Series jaw crusher was first developed and widely used in the domestic market because of its simple structure and relatively low price.
Pew series jaw crusher is improved on the basis of PE series. Great changes have been made in equipment structure, adjustment device and protection device, which greatly improves the crushing efficiency and crushing ratio of jaw crusher.
The all-in-one machine belongs to a new generation of jaw crusher products, and its equipment structure, use function, production efficiency and other indicators reflect the modern advanced technical level. Compared with PE and PEW, the biggest change of the all-in-one machine is to place the motor on the body.
Jaw crusher as the “leading brother” of crushing section At present, although the PE jaw crusher is still the most widely used series, with the development of technology and the increase of time cost, the advantages of the integrated machine in terms of convenience, high crushing efficiency and safety in replacing parts and components will be self-evident.
