Problems solved by technology

If there is too much feeding, it may cause the crusher to block the material, resulting in long-term downtime for maintenance; if the feeding is too small, the operating efficiency of the crusher will be low, which will affect the production efficiency of the entire production line.
[0004] At present, the crusher adopts the method of manual feeding, and the mouth of the crusher needs to be guarded and operated by a special person. Working in a harsh environment for a long time is not good for people's health, and the smoothness of feeding is not easy to control.

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0023] The inventors found that the current of the crusher changes continuously with the amount of materials. Generally speaking, the more materials in the crusher, the greater the current, and the less the materials, the smaller the current. Therefore, a scheme to adjust the feeding speed according to the current change of the crusher is proposed.

[0024] figure 1 It is a schematic flow chart of an embodiment of the control method for crusher feeding in the present invention.

[0025] Such as figure 1 As shown, the method of the present embodiment includes:

[0026] Step S102, detecting the current value of the crusher.

[0027] An exemplary detection method is to pass the current of the main shaft motor of the crusher through the current transformer, then through the cu...

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...
