Coal briquette machine is used for making coal fines, coke fines, charcoal powder, carbon black, iron ore fines, mineral powder, metal dust, cast iron dust, mill scale, manganese ore fines, fluorite powder, gypsum powder,ferrosilicon powder, and phospho gypsum powder, nickel alloy, blast furnace ash, converter dust, coal gangue, Kaolin clay, MgO, NPK, graphite, oil shale, potash fertilizer, urea fertilizer, sea sand powder etc. into briquettes. This series of charcoal briquette machines can be used to make charcoal briquettes of different shapes. The raw material comes from small size waste charcoal broken in storage or while transportation, or comes from charcoal chunk after biomass burned. With this machine, the waste charcoal chunk can be made into charcoal briquettes or charcoal stick and recycled for barbecue, room heating etc. These briquettes can be designed of oval shape, egg shape, pillow shape etc. This machine is widely used in coal industry, metallurgy industry, chemical industry etc.Coal Ball PressMachine Technical parameter: The briquettes have the features of high density, high strength, and high hardness since the raw material was suppressed by roller under high pressure. Besides, this machine is also suitable for suppressing all kinds of mineral powder, metal powder, coke powder and others. The process consists of raw materail---curshing---mixing(add binder)---briquetting---drying.Features of the charcoal coal briquette machine: 1. We have double roller type, four roller type, high pressure type, dry powder type, wet powder type, etc, could meet your different requirements. 2. The main engine revolutions are adjustable, and the machine equipped with a helical feeding device, double roller with four time pressure. 3. The powder briquette making machine"s mold wheel was made of 65Mn and CrMo Alloy, which has the quality of high strength, wear-resisting and long service life. 4. The production could be egg-shape, oval-shape, square-shape,...
