The trunnions also define a bearing surface for permitting rotation of the drum. The drum is filled with a charge of forged steel balls to a level just below the bottom of the trunnions. As the drum is rotated, the balls are continuously lifted and tumbled by gravity onto the coal to pulverize the coal.
