Everything you need to know about clinker/cement Grinding
Increase mill feed temperature; Increase the separator returns, and/or increase its temperature by moving fresh air damper (but beware of maintaining the underpressure). For single-pass, recycle the gas from the fan outlet. Decrease mill ventilation (increases air residence time) à air gets warmer à increases amount of water that it can take.
Effects of grinding aid dosage on circuit performance and cement
This can be explained as follows: The residence time of the ground cement was shortened by increasing the dosage of GA dosage, and therefore the mill product became coarser. This caused an increase in the amount of the material which returned to the mill until the system reached the steady state conditions.
How to Improve Cement Ball Mill Performance
Table 1 From Table 1 we can learn that if the particle size of the feed material is reduced from 25 mm to less than 2 mm, the mill output can be increased by at least 60%, which is relatively consistent with the actual production. There are two methods for clinker pretreatment: pre-crushing and pre-grinding.
