How To Control The Overflow Of Ultrafine Mill

When the ultrafine mill works, the amount of overflow will have a greater impact on production, so the control of this part is more important. Through research, it is necessary to solve this part, and it needs to be solved from two aspects. Analyze the content of these two aspects:

1. Adjust the gap between the grinding roller and the grinding disc and the grinding disc and the ventilation ring before starting the machine.

(1) Adjustment Of The Gap Between The Grinding Roller And The Grinding Disc

In the production process of the ultrafine mill, the grinding roller and the grinding disc play a very large role. After the material enters the grinding chamber, it falls on the grinding disc. With the centrifugal force generated by the grinding disc, it is shoveled by the blade. Grinding between the grinding roller and the grinding ring is a rough grinding process. From the description of this process, it can be seen that the grinding roller and the grinding disc play an important role when the mill is working, and its function requires both Maintain a normal gap between 5-10 mm, if it is larger than this size, it will cause an increase in overflow;

(2)Clearance Adjustment Between The Grinding Disc And The Ventilation Ring

In the ultrafine mill, generally, it is necessary to check the gap between the grinding disc and the ventilation ring before starting the machine. Generally, the required value is less than 10 mm, in order to carry out normal production, otherwise, through the ventilation ring. The required airflow speed is greatly increased. At this time, the wind speed inside the mill increases, so the amount of material brought out will be more, which is also an important reason for increasing the overflow amount;

2. Control Of Total Exhaust And Power Of The Mill

In general, before the start-up, the ultrafine grinding machine will set various parameters according to the required capacity and the size of the finished product. Whether the parameters are reasonable is very important for the production of the machine, we require equipment. The total exhaust and power, as well as the pressure of the grinding roller, must be strictly controlled within a reasonable range, so as to ensure the smooth operation of the production, otherwise, the ultrafine grinding machine in the grinding of materials , there will be an increase in the amount of overflow, these parameters are too large or too small are not conducive to the production.
