Grinding mill for superfine ground granulated slag The fineness of superfine ground granulated slag can be controlled between 325~2500 mesh /47-5 micron. The grinding machinery are also widely applied to non-inflammable, non-explosive and brittle materials with mohs hardness under six, such as chalk, limestone, dolomite'kaolin, talc, magnesiteillitepyrophyllitvermiculite, sepiolite, floatstone, attapulgite, rectorite, diatomite, barit, gypsum, alum earth, graphite fluorite, variscite, potash ore etc, totally more than 100 kinds of materials. Advantages: 1. High efficiency Under the same final size and power, the product capacity of ultrafine mill is twice than jet mill and agitation mill. 2. Longer lifetime of spare parts The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 2-5 years. 3. High safety and reliability: There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen. 4. High fineness of products The product fineness can reach D97≤ 5μ m. 5. Environment friendly The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard. Production Line Configuration The whole set HGM Ultrafine Mill consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.
