Mill outlet out of powder and powder uneven reason analysis

A problem often occurs in the operation of Raymond mill is the feed opening a powder or a small amount of powder that yield is low, produce the fault reasons mainly include the following several aspects: one, does not adjust the lock powder feeder, Mifengbuyan resulted in powder ceiling; second, knife blade wear phenomenon is serious, so that the material cannot scoop up; third, duct is blocked. Lastly, it may because of good sealing and led to the pipeline leakage.

Countermeasures: in order to solve Raymond Mill powder phenomenon. According to the reasons for the failure analysis of solutions are as follows: first to deal with the powder locking device inspection and timely readjustment; secondly, the damaged blade to replace; then will be blocked duct cleaning and re feed mills. Finally, seal pipe, to prevent leakage.

Uneven powder material, failure analysis: fine powder product is not uniform, the formation of the powder is too thick or meticulous, fault reason mainly includes two aspects: one, because the classifier blade was wear, and can not play to the effective action of classification; secondly, it is also possible to because of the air blower is not appropriate or impeller wear serious. Countermeasures: to solve the phenomenon of uneven refined powder should be timely replacement of grader blades, which can effectively solve the powder is too coarse, and powder meticulous should improve air flow to be resolved.
