Between the two grinding roller which rotate in two opposite directions, small dry particles bear extremely high pressure. The fine particle materials are crushed into powder or uniform shapes. In the cement industry, this type of gearboxes can be applied to raw materials, pregrinding, and final-cement grinding roll presses. In the mining industry

(copper mine, gold mine, diamond mine, and etc.), mining roll presses are usually utilized before other grinders. NGC always provides reliable drive devices to customers.
