Raymond mill crashing auto control method and equipment thereof

Abstract

The invention discloses an automatic control method of Raymond mill grinding. Equipment can be automatically adjusted so as to ensure that the Raymond mill runs at an optimum load condition. The invention also discloses an automatic control method and an automatic control device for implementing the Raymond mill grinding. The device not only can real-time monitor the operation condition of feeding, grinding, airflow rough separation in a Raymond mill workshop, but also can automatically adjust feeding and grinding according to the main engine load. Furthermore, the invention also can automatically adjust a blower on the basis of technical requirements, which realizes the automation of the airflow rough separation and overcomes the shortcomings of manual operation operated by workers. Theinvention adopts a self-adaptive control method to adjust and control and employ a programmable logic controller as a control core. No manual operation is needed in the whole production process, thusrealizing the fully automatic adjustment of feeding, grinding and airflow rough separation, saving energy, greatly reducing equipment failure rate and increasing productive efficiency; through using asupervisory control computer witch can carry out a real-time monitor, the working parameter and index parameter of the PLC can be modified at any time so as to improve production efficiency.

Description

technical field [0001] The invention relates to an automatic control method and device for Raymond mill crushing that can realize real-time monitoring and automatic optimal control of the working conditions of Raymond mill vibration feeding, crushing, and airflow coarse separation in a crushing workshop. Background technique [0002] Raymond mill is a kind of pulverizing mill imported from abroad. At present, there are many domestic productions. It is suitable for the preparation of various mineral powders and coal powders, such as fine powder of raw material ore, coal mine, diamond, silicon carbide and other materials. processing. Raymond mill looks like an upright steel container from the appearance, with air inlet and outlet, and a material inlet in the middle. The structure of the machine is mainly composed of main engine, analyzer, blower, finished product cyclone separator, fine powder cyclone separator and air duct. Among them, the main engine is composed of a frame...

AI Technical Summary

Problems solved by technology

Due to the nonlinearity and hysteresis of the feeding controller, workers cannot accurately control the feeding speed during the feeding process

If the feeding speed is too slow, the production efficiency will be low; if the feeding speed is too fast, it will easily block the equipment, cause shutdown and burn the motor, affect production, and greatly increase maintenance costs

Particle size sorting is also realized by workers operating blowers and analyzing machine adjustments. The control accuracy is not high, and the sorting accuracy is low, which increases the difficulty of subsequent processing.
