Static electricity is charged or polarized depending on the substance. Therefore, a feasible measure is to avoid the use of an easily charged insulator, and to use a material that is difficult to generate static electricity by combination. (2) Promote the leakage of electric charge: In the disaster countermeasures, the simplest method is to ground.

03/10/2017 Static ball charge measurement. The mill must be stopped for the static ball charge to be measured. Drop the weighted rope in the ball port at the same reference point on the ball port as the initial ball charge reading. The distance between the first mark on the rope and this second mark is the depth of the ball charge.
Ball mills may build up static charge, more so if the drum is made of plastic. This makes grinding flammable or pyrotechnic materials, such as metal powders, organic powders or black powder, extremely dangerous as air-powder mixtures are explosive, while in the case of black powder a singe spark can cause detonation of the powder.
