The gearbox on a gear-driven pellet mill is totally enclosed, protecting the operator from any moving components, thus any failure of the transmission will be contained within the gearbox enclosure. The rotating members of a belt drive are normally enclosed in sheet metal covers, offering protection to the operator in case of a failure.
Part Three: Raw Mill. Process of Raw Mill The proportioned raw material is feed first to a grinding mill. In the mill, particles ground in to very fine sizes. In the grinding unit, drying, grinding and mixing takes place simultaneously. Hot gas from clinker burning unit is passed into the grinding unit to assist the drying and grinding process.
