Raymond also known as Raymond mill. Can replace the ball mill is a highly efficient, high-fine milling equipment using closed loop. The Raymond machine for small and medium mining, chemicals, building materials, metallurgy, refractory materials, pharmaceuticals, cement and other industries. Widely used in metallurgy, building materials, chemicals, mining and other fields, were grinding materials processing mining products, suitable for processing Mohs hardness below seven, humidity below 6% of various non-explosive mineral stone mill, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite Peng, stone, bauxite, iron oxide red, iron ore and other mills, fineness at 613 microns to 440 microns (0.613 mm -0.044 mm), through joint action analysis machine and fans can meet the different requirements of the user's satisfaction. Host work process is driven by rotation of gear center axis, the upper end of the shaft is connected to plum rack, rack mounted roller device and that it is not only the formation of swing pivot rotation around the center, while the roller ring revolves around the mill, roller itself because friction and rotation. Plum frame with the bottom of the blade system, its position in the lower end of the roller, the roller blade and process with the transfer of the material between the throw shovel-speed mill feed roller and grinding ring, forming a litter layer, the material layer internal and external rotation of the roller by the centrifugal force (ie squeeze pressure) the material is crushed, that thus reached milling purposes. High-speed milling machine _ in Lei machinery (certified) _ mill provided by Zhengzhou Machinery Co., Ltd. Lei. Lei Zhengzhou Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum limits to meet customer needs.
