Heavy Duty Girth Gear For Rotary Mill Equipment

A girth gear is a large rotating ring gear that encircles a mill, kiln, or other rotary equipment. It meshes with a smaller pinion gear driven by a motor, transmitting torque to rotate the drum. The gear is typically mounted on the equipment shell and rotates with it, enabling smooth, continuous motion for grinding, mixing, or processing materials. Applications: Girth gears are widely used in heavy industries, including: Cement plants (rotary kilns, ball mills). Mining (ore grinding mills). Chemical processing (mixers, dryers). Power generation (coal pulverizers). Their robust design ensures reliable power transmission in high-load, low-speed operations.
