When grinding the material because there is some water, flour milling machining bluestone Raymond mill grinding indoor heat, moisture evaporation, and the whole of each pipe interface is not tight, the outside air is sucked into the circulation increased pressure to ensure mill work in the vacuum state, the increase in gas flow through the duct into the dust, after being purified into the atmosphere. Raymond mill bluestone powder machine structural characteristics: 1, processing bluestone powder Raymond mill finished powder fineness uniform, through screening rate of 99%, which is difficult to have other milling equipment. 2, Raymond mill powder processing bluestone electrical system with centralized control, nobody can achieve the basic milling plant operation and maintenance. 3, Raymond mill powder processing bluestone important parts are made of high quality steel mill, wear-resistant parts are made of high-performance materials, machine wear, reliable operation. 4, processing bluestone powder Raymond mill is three-dimensional structure, small footprint, complete and strong, expect the finished powder independent self-contained production system from the block. 5, Raymond mill processing bluestone powder powder machine adopts airtight gearing and pulley gear box, transmission smooth, reliable operation.
