GYM Roller Press Gearbox

Between the two roller presses 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, the roller press can be applied to raw material, pre-grinding, and finally cement grinding. In the mining industry (copper mine, gold mine, diamond mine, and so on), the roller press is usually installed at the front of other grinders. NGC always provides the reliable drive devices for those customers.
