How to feed the vertical roller mill?

The feeding control driving device used by Vertical roller mill mainly has two forms: mechanical pneumatic servo feeding and electric control frequency conversion. Feeding control system controlled by the material level detection, flow control and parts, such as the system through the Vertical roller mill feed tube material in the material level of detection, adjust feeding door opening Angle and feed speed of roller, to meet the needs of powder into the ground. The structure and properties of the feed system powder sensor are briefly introduced. The material position sensor in Vertical roller mill feeding tube is commonly used in two kinds of mechanical gravity-type sensor and electrical material position sensor.
Mechanical gravity type material level sensor principle is: after dendritic valve for material level signal, mechanical lever position signal through pneumatic valve is passed to the pneumatic servo system, through the system of the working cylinder executing open door, switch the size of the feed roller, roller clutch brake operation control. The sensor structure is simple, low cost and easy to adjust, but the stability and reliability are not ideal. The electrical material position sensor obtains the material bit signal by the electric sensor.
For change of material level signal, the conversion control circuit, control frequency converter drive drive motor of Vertical roller mill feed mechanism to realize the feed roller feeding speed control and roller clutch (electric clutch or pneumatic clutch). The dielectric constant of the capacitive sensor is greatly influenced by the dielectric constant of the material, which is high in the sensor and circuit. 3. The design of the control scheme of feeding system control scheme is realized by the independent way of the feeding system from the grinding system of Vertical roller mill. The feeding speed of feeding mechanism is regulated by inverter driven deceleration motor, which is the feeding machine alone.
Coarse adjustment of feeding flow:
In feeding mechanism, the manual feeding device is retained, which is the fan feeding valve. The feeding volume is coarse by manually adjusting the opening of the feeding valve. The general system test will be adjusted. No more frequent adjustments. Continuous adjustment of feeding flow: through the infrared position control system, control feeding speed of the feed roller. It can satisfy the feeding system to feed a certain amount of powder, and feed the production technology of the grinding area at a certain speed. The manual feeding system can adjust and adjust the feeding system, which can bring great convenience to the user's use and adjustment. All in all, Vertical roller mill control system automatically adjusts the feeding amount to ensure the balance of feeding quantity and grinding. It avoids the overflow of feed drum powder and the running time of grinding roller. Make the feed more uniform. My company through the study of Vertical roller mill feeding device control system, optimized design of equipment, a new efficient grinding equipment of feed system design, high efficiency, welcome to choose and buy.
