How I built a quick and easy homemade ball mill
The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a finetoothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor was mounted using screws on only one side, which were deliberately left loose. This allows the motor to pivot downward under its own weight to put tension ...

learn moreWhat Leads to the Abrasion of the Cement Ball .
The main reasons that lead to the abrasion of the ball mill are: First, the big impact force causes microscopic wear which mainly appears somewhere inside the machine people cannot see. Second, the big impact force leads to the deformation of the cement ball mill. At last, the abrasion is brought by the corrosion. The wear of the cement ball mill lining plate mainly accounts for the type and ...
