Abstract

The invention discloses a crusher feeding control method and device and relates to the field of engineering machinery. Continuous changes occur with the amount of material according to current of a crusher, the current value of the crusher is detected and compared with a preset current value, if the current value is higher than the preset current value, feeding speed of a feeder is decreased, and if the current value is lower than the preset current value, the feeding speed of the feeder is increased; automatic feeding is achieved, few blockages and overflows occur, and it is possible to ensure feeding smoothness of the crusher and improve production efficiency.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to a control method and a control device for crusher feeding. Background technique

[0002] Sand making, stone making and recycled aggregate production lines are also called fixed crushing stations. This kind of production line is generally built in a place where raw materials can be obtained nearby. The raw materials used are generally raw materials with relatively large particle sizes after explosive blasting. Raw materials with relatively large particle size first enter the coarse crushing for crushing, and then the aggregate with relatively small particle size enters the next step for crushing, screening, and grinding to obtain fine aggregate, machine-made sand and recycled bone that meet the specifications. material.

[0003] Since the crusher is the first link in the sand and stone production line, the smoothness of its feeding directly affects the production efficiency o...
