A mill automatic feeding control system and control method

Abstract

The invention discloses an automatic feeding control system and method for a powder grinding machine. The system comprises a control unit, a man-machine interaction device, a silicon controlled rectifier, a silicon controlled rectifier toggle and an electromagnetic vibrating feeder. The control unit, the silicon controlled rectifier, the silicon controlled rectifier toggle and the electromagneticvibrating feeder are electrically connected in sequence. The control unit is further electrically connected with the man-machine interaction device. Parameter state set values and output set values are input into the control unit through the man-machine interaction device. The control unit collects parameters of a host, a fan and a discharge outlet in real time, appropriate output values are determined by comparing the collected parameters with the parameter state set values, and the control unit drives the silicon controlled rectifier through the silicon controlled rectifier toggle so as to control the electromagnetic vibrating feeder to achieve steady-flow constant-pressure automatic feeding. By means of the system and the method, material conditions in a grinding cavity can be judged inreal time according to host and fan load conditions of a grinding machine system, a feeding device is automatically controlled to react in advance for stable feeding, and materials in the grinding cavity are kept balanced to achieve the low noise purpose.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a pulverizer automatic feeding control system and control method. Background technique [0002] The pendulum mill is a traditional grinding type. In the process of use, the traditional electromagnetic vibration controller is used to control the feeding of the feeder through a manual or simple controller according to the current of the host and the fan. This method is often used. The thickness of the material layer between the grinding roller and the grinding ring of the mill body is uneven, resulting in a loud noise like thunder, or the backlog of the material in the grinding chamber due to wet and difficult grinding of the raw material will also cause the mill to produce loud noise. , the pendulum mill is also commonly known as "Raymond mill". How to judge the material condition in the mill cavity in real time according to the load of the host machine and the fan of the mil...
