New feeding device of Raymond Machinery Factory

Raymond Machine Factory's new feeding device > The feeding system of Zhengzhou Shuguang Raymond Machine Factory's new grinding mill uses a capacitive sensor to detect the material level and adjust the feeding amount with variable frequency. It has extremely excellent performance and can change the feeding of the motor in real time. The feeding valve is first manually operated for coarse adjustment, and then the automatic control system changes the feeding speed for fine adjustment. The manual and automatic are used together to achieve good results.
> According to the working principle, the sensors of the feeding device can be divided into capacitive infrared type and ultrasonic type. Among them, the capacitive type has dot type and rod type. The capacitive type does not have a signal generating and receiving device and relies on observation. The level of the material in the barrel changes the capacitance of the sensing element for measurement. The rod sensor has a simple structure and the output signal is continuous and stepless, so it is the most widely used. The speed regulating mechanism can automatically adjust the speed of the feeding roller according to the set upper and lower limits of the material level, or it can also make the feeding roller work at a set fixed speed. By adjusting the rotation speed of the high-pressure Raymond mill feeding roller to change the gradient of the feeding amount, the effect is good.

The feeding device can effectively improve the utilization rate of the equipment and ensure the stability of the powder making process. The adjustment of the root feeding amount can be performed by changing the feeding gap by moving the valve or changing the speed of the feeding roller. The material level sensor regulators of the mechanical feeding automatic control system are all gravity-type. The gravity-type material level sensor can adjust the rotation speed of the feeding valve or feeding roller through levers and pneumatic actuators to control the feeding amount based on the profit and loss of the material level in the barrel. Whether it is a fan type or other forms, the feeding valve controls the feeding amount by changing the section of the feeding gap. The disadvantage is that the gradient of the adjustment amount is large.
