About the PE and PEX crushers

PE series and PEX series jaw crushers are for primary and tertiary crushing respectively. They are classical products developed independently by Kunming Ciba Mining Machinery Co., Ltd. and has been our bestseller for more than 30 years. They are noted for their simple structure, high durability and outstanding performance. They are widely used in crushing operations in metallurgy industry, ore mining, infrastructure material production, chemical industry. They are applicable to primary, secondary and tertiary crushing processes of ores and rocks with compressive strength below 250 Mpa. Their advantages are high size-reduction ratio, uniform product size, low energy consumption, and convenient maintenance.

They consist of a rack, a swinging jaw, an eccentric shaft, toggles, a pitman and springs. The rack and the swinging jaw are equipped with a fixed board and a moving board respectively. When the eccentric shaft rotates, the swinging jaw drives the moving board to make periodic reciprocating motion around the pivot against the fixed board. Therefore, ores between the two boards are crushed and discharged through the outlet due to gravity. By adjusting the size of the outlet opening, required product size can be accquired.

The energy-saving device is developed by our company and granted independent intellectual property rights which compatible with the jaw crusher. It uses a low-power motor to drive a high-power equipment in order to save energy by 20-40%. It’s an ideal supporting device for PE and PEX series jaw crusher to achieve the purpose of saving energy.
