Reasons affecting the fineness of vertical roller mill materials

If the vertical rotation speed of the main vertical roller mill is too high or too low, it will have a great influence on the discharge size of the product. However, in fact, we can adjust the speed of the motor by adjusting the current of the motor, because the gear reducer and motor of the grinding equipment are linked by the accessory shaft of the vertical mill, which is a good method.
