Abstract

The invention discloses a hydraulic control system of a crusher. The hydraulic control system comprises two hydraulic cylinders, magnetic exchange valves, ball valves, two-way speed control valves, a proportional pressure and flow combined control valve, pressure relays, an air cooler, travel switches, pressure sensors and displacement sensors. Piston rods of the hydraulic cylinders are controlled by all the magnetic valves and all the speed control valves to operate at a set speed, and materials are crushed. By means of the hydraulic control system of the crusher, it can be guaranteed that impact rammers can not intervene, the operating frequency can be adjusted, and reciprocating impact crushing work can be automatically completed through the system. The pressure of the system can be automatically increased under the hard material condition, the materials are extruded and crushed, and crushing efficiency is improved. Normal work of the system is guaranteed to the maximum degree through the limited control valves, the components are in the intermittent work state, and work reliability is improved; when parts of the components fail, replacement can be carried out without halting, and the working efficiency of the crusher is improved.

Description

technical field

[0001] The invention relates to a crusher control system, in particular to a crusher hydraulic control system. Background technique

[0002] With the rapid development of the economy, industries such as highways, high-speed rail, water conservancy, chemicals, and cement are also developing vigorously, and the development of these industries is inseparable from some necessary raw materials such as ores, and these raw materials are generally relatively large and unsuitable. For direct application, these raw materials or recycled waste need to be crushed and processed for corresponding production construction and processing. Therefore, high requirements are put forward for the working efficiency and reliability of the crusher.

[0003] At present, the commonly used crushers are jaw type, rotary type, hammer type and impact type. The jaw crusher is an intermittent crushing device that uses two jaw plates to squeeze and bend materials to turn large stones into s...
