In addition to diamond and fullerene, graphite is the third modification of carbon. There are three principal types of natural graphite, each occurring in different types of ore deposit:Crystalline flake graphite (or flake graphite for short), Amorphous graphite, Lump graphite (also called vein graphite). Graphite is mined around the world by both open pit and […]

Grinding Machine for minerals processing is widely used in mining, mineral industry, coal, cement. Our grinding mills includevertical roller mills,superfine roller mills, Raymond mills, hydrated lime production lines, ultrfine ring roller mills,crushers, sand making machine,sand and powder integrated grinding machine. Each of the different types of grinding mills are available in a variety of sizes, […]

The hardness of a material is probably the most important characteristic to consider when deciding on what type of mill to choose. This page is about hardness of kinds of minerals.

Coal gangue production of cement industry: production of ordinary Portland cement; production of special cement; production of non-clinker cement. Coal gangue production of building materials: sintered coal gangue brick, good quality, color uniformity; production of coal gangue light aggregate, lightweight aggregate is less for relative density of the concrete, and the selection of a class […]

The ring and roller of grinding mill are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate. Designed […]

Vermiculite powder is usually 20-40mesh, 40-60mesh, 60-80mesh, 200mesh, 325mesh and 800mesh. The vermiculite ore is grinded into powder after high-temperature roasting. In this vermiculite grinding plant, Raymond grinding mill and three-ring ultrafine grinding mill is used. Vermiculite Raymond grinding mill the common grinding mill used in stone crushing and screening plant and mineral ore mining […]
