Problems solved by technology

Since the feeding speed of the feeder is generally constant, if the volume of the stone is relatively small, the feeding speed of the feeder will not be fast enough, and the crusher will not produce at its maximum output. If the volume is relatively large, the feeding speed of the feeder will be too fast, the crusher may be overloaded, and the stones will accumulate in the crusher due to untimely crushing.

Embodiment Construction

[0008] The basic structure of a feeder-crusher automatic control system of the present invention can be found in figure 1 , including a sensor, a control center and a speed governor, the sensor is installed on the crusher, the signal output end of the sensor is connected with the control center, the output end of the control center is connected with the speed governor, and the control center can be PLC ( Programmable logic device) and the corresponding control circuit, which can be used to receive signals, process corresponding information and send command signals, and the control terminal of the governor is connected to the feeder.

[0009] Using the above system, the automatic control of the feeder-crusher can be realized. The specific method is as follows: the sensor detects the operating status of the crusher and sends the relevant information to the control center; when the information sent by the sensor indicates that the crusher When there are too many stones in the cru...

Abstract

An automatic control system for the feeder-crusher system has a sensor arranged on crusher, a speed regulator with a control input connected to feeder, and a control center connected respectively to said sensor and speed regulator.

Description

technical field [0001] The invention relates to an automatic control system, in particular to a feeder-crusher automatic control system. Background technique [0002] Now, due to the rapid development of the construction industry, the demand for building materials is also increasing. As the main equipment for stone processing, crusher is widely used in this industry. Most of the current stone crushing processing methods are to add stone to the crusher from the feeder. When the crusher is working, if the stone is too large, its crushing speed will be slightly slower, and if the stone is small, the crushing speed of the crusher will be faster. Since the feeding speed of the feeder is generally constant, if the volume of the stone is relatively small, the feeding speed of the feeder will not be fast enough, and the crusher will not produce at its maximum output. If the volume is relatively large, the feeding speed of the feeder will be too fast, the crusher may be overloaded...
