Ball Mill Not Working

The problems appeared in the use process ofball millcan be dealt with like this the first common problem no powder or little powder with low output reasons 1 the lock powder device isnt adjusted well and the sealing is loose which lead to the powder suckback 2 the scraper knife is of great abrasion and cant scoop up the materials
