Introduction of Raw Mill
Raw mill is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing, such as glass ceramics industry production, various ores and other materials may be grinding of dry or wet grinding. Also applies to the metallurgical, chemical, electric power and other industrial and mining enterprises to smash all kinds of ores and other materials may be grinding. Can be used to open circuit grinding, also applies to circle and powder feeding machine. The flow of grinding. The device is reasonable in design, high adaptability to raw materials, high running rate, big crushing ratio, high yield, easy operation.
Raw mill structure design
Raw mill uses large cap, namely the end cover and the hollow shaft is an integral casting. In the streamlined design unique big end cover and a discharge system, reduce the ventilation resistance, increase the effective volume, easy to discharge, improving mill output. Raw material mill as single silo structure, mill lining plate of combination design, based on the raw material mill lining plate structure in different phases with different, greatly improving the grinding efficiency. Raw material grinding working internal pressure to negative pressure, and effectively prevent the occurrence of powder leakage phenomenon. Hot air for drying kiln waste gas into the air, raw materials used in the insulation measures of grinding, drying ability of the material to reach 6% ~ 8%. Raw material mill electric control allow DCS interface, to meet the needs of users of centralized control.
