In the process of using Raymond mill, sometimes it is necessary to re-adjust the air volume control valve to ensure the normal operation of the equipment and improve the grinding efficiency, usually including:

Change product fineness requirements:

If there are new requirements for the fineness of the finished product during the production process, the air volume may need to be adjusted. Increasing the air volume can improve the fineness, but also reduce the yield; Reducing air volume reduces fineness but may increase production.

Yield change:

When it is necessary to increase or decrease production, it may be necessary to adjust the air volume control valve. Increasing the air volume helps to increase the yield, but it is necessary to ensure that the fineness of the material is not affected by excessive air volume.

Material characteristics change:

Different materials have different physical and chemical properties, such as humidity, particle size distribution, hardness, etc., and these factors can affect grinding efficiency and finished product quality. Therefore, when the type of material is replaced or the characteristics of the material change, the air volume may need to be re-adjusted to adapt to the new material characteristics.

Changes in operating status of the mill:

After a long period of operation, the mill may have problems such as wear or blockage, which will affect the flow efficiency of the air duct. If it is found that the operating efficiency of the mill is reduced, it may be necessary to adjust the air volume control valve to optimize the operation.

System pressure changes:

If the pressure in the intake or exhaust system of the mill changes, it may be necessary to adjust the air volume control valve to maintain the balance of system pressure and ensure the normal operation of the mill.

Environmental factors:

Changes in ambient temperature and humidity may also affect the operating efficiency of the mill and the quality of the finished product, so it may be necessary to adjust the air volume when environmental conditions change.

When adjusting the air volume control valve, it should be carried out gradually, and the operating condition of the mill and the quality of the finished product should be closely observed to ensure that the adjustment achieves the desired effect. At the same time, the operator should make adjustments according to experience or the guidance of the equipment manufacturer to avoid unnecessary damage to the equipment.
