Coal mill is the traditional basis of hammer crusher on the improvement comes, grinding fineness good. Coal mill to improve the traditional butter oiling mouth slime mill equipment efficiency, centralized oiling way, even if it is constantly oiling the machine can also be achieved, so that the grinding efficiency is higher. Due to the special design and gangue crusher for crushing humidity of materials no requirements, wet materials are crushed, rainy days do not delay production. Coal mill role uses: Coal mill is particularly suitable for crushing brick slag, shale, coal cinder, coal gangue, construction waste and other materials, to solve the added coal gangue, coal cinder brick as expected, within coal gangue, shale production standard bricks, hollow brick material crushing wet problem; fuel. Coal mill is mainly used cinder, coal gangue, slag, slag, limestone, coke, galena, siderite, sphalerite, limonite and other large mill slime promotions, compressive strength of not more than 150Mpa material, the material is particularly suitable for the requirements of smaller size, moisture content greater crushing brittle materials, widely used in chemical, power, aluminum, mining, building materials, mineral processing and other industries. When broken material should be higher fines content screened in advance. Before crushing the material contained in the powder too, will affect the crushing capacity. Because the powder during transport, easy to adhere to the conveyor belt thus affecting transport of materials, a direct result of gangue crusher feed rate and feed rate, crushing efficiency also will be greatly reduced. For much of the material fines content, should advance once sieve. Another stone contains more impurities slime mill will affect crushing capacity. When formed into a pellet mill slime higher supply when used, must promptly apply for grease fittings. Finished size requires less material in the gangue grinder with contact friction the more the number of accessories, will also increase the degree of wear. Crushing the raw material requirements of the final particle size smaller, slower crushing speed, and ultimately affect the crushing capacity. Therefore, in the process of crushing, to timely for all parts gangue grinder smear grease to reduce wear. Small slime grinder features, Guangdong direct mill slime much money, grand supreme quality provided by the Zhengzhou City grand Machinery Manufacturing Company Limited.
