The ball mill is powered by a fairly robust 12v dc motor salvaged from a junked printert had a pulley for a finetoothed belt on itt was left in place and it seems to drive the heavy round rubber belt well without slippinghe motor was mounted using screws on new and used ball mills for sale ball mill
A dc motor offers its maximum torque at low rpm where you need it most so the full speed horsepower rating of an acdc motor can be a little deceiving as far as offering practical usable power the dc motor also offers smoother and quieter operation to power and control the motor a more sophisticated speed control unit is
