air jet classifier Structure characteristics

1.The unique suspension dispersing mechanism makes the material fully dispersed in the jet airflow field, improves the dispersion effect and ensures the improvement of the powder selection efficiency.

2.The classification effect of horizontal eddy current is obviously effective, the reasonable flow field design, the material selected flow field and force stability are consistent, so the separation efficiency is higher.

3.The rotor has small diameter, compact structure, small transmission power, stable and reliable operation, easy arrangement and small civil quantity.

4.The change of product fineness and particle gradation can be realized only by the speed of the speed regulating motor and the air volume of the system.


Equipment operation and product fineness adjustment

1.Motor start, stop, spindle speed and lubrication pump control by the control cabinet control. Specific wiring, operation, adjustment methods and precautions refer to the subsequent control cabinet instructions and inverter instructions. The direction of the spindle rotation must be consistent with the volute air inlet direction, that is, look down, the rotor should rotate clockwise.

2.Grease the grease pump before running.

3.The fineness of the product and the classifier is adjusted by changing the spindle speed and air volume system. By increasing the rotational speed, the specific surface area of the product can be increased. The air volume of the system has a greater impact on the product fineness, generally increase the specific surface area of air products smaller, reduce air volume product surface area increased. The the spindle speed and air volume system should be suitable with the adjustment, air classifier speed and system according to the specific conditions of the specific, determined through trial. If the volume is too large or too small, even if the classifier speed may not be appropriate, accurate control of product fineness, so the volume must be controlled in a reasonable range.

In the operation of equipment to observe the status of equipment operation, pay attention to current and start stop condition of the main motor lubricating oil pump, observe and record the decline in oil pump in oil tank, when the grease level is only 1/3 when it should be timely to the storage tank in the grease to the ceiling height.
