The Raymond Mill is a grinding machine, suitable for the preparation of various kinds of mineral powder and coal powder preparation. SBM has launched three upgrade series of Raymond Mills, MB5X Pendulum Roller Mill, MTW European Grinding Mill and MTM Medium-speed Grinding Mill respectively.Each machine is capable of making 350-400 molds an hour. Once the sand mold is created and the molten iron hits the right temperature, we pour the liquified metal into the mold. Since sand melts at a higher temperature than iron, the mold holds its shape. When the cast iron has cooled, the castings move along a vibratory conveyor to shake off.
