With regard to the use of powder mill belly bulge appeared in the process, there are several factors:

Firstly, to see whether the powder mill to the mine mouth spit normally expected, if not properly spit expected, is likely to lead to bulging belly powder mill;

Secondly, listen to the sound of the powder mill, if the smaller changes the sound stuffy, it is very possible to be ball bulging belly;

Then, look at the current powder mill control cabinet, so they think that when the current value is likely to become larger Mill expansion belly of the precursor is in fact not the case, if the ball bulging belly, its current value is become small.

Powder Mill Operating principle: This powder mill is horizontal type and tubular running device, has two warehouses. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. In this warehouse , there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force ,at this time , the steel ball is carried to some height and falls to make the material grinding and striking. After grinded coarsely in the first warehouse, the material then enters into the second warehousefor regrinding with the steel ball and scaleboard. In the end, the powder is discharged by output material board and the end products are completed.
