ABSTRACT:
A pulverizer having four hydraulic drive motors for rotating the grinding ring or bowl. The motors are mounted so as to be easily accessible, so that one or more can readily be removed for repair during which time the pulverizer can remain in operation. The speed of rotation of the grinding bowl can be varied by either changing the pressure of the driving hydraulic fluid, or by stopping the supply of fluid to one or more of the motors.
