BH Raymond grinder is the new generation of high-fine powder grinding equipment with high-efficiency and closed cycle, which can replace the ball mill. And it can meet different requests under the combined effect of analyzer and fan.

BH Raymond Grinding Mill Advantages   1. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From the crushing of raw material to the grinding and packing, it is an independent production system. 2. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach. 3. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably. 4. Main parts of the whole plant are made of cast and steel of high quality. The technics is so subtly that insures the durability of whole plant. 5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room. 6. Equip with efficient dust collector, no dust leaking, clean working environment.

BH Raymond Grinding Mill Application

The raymond mill is mainly used in processing powder of mineral materials of metallurgy, building materials, chemical industry, mining, etc. It can grind non-flammable and non-explosive materials with moisture less than 6% such as Feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, slag, slag, activated carbon, dolomite, granite, iron oxide yellow, bean cake, chemical fertilizer, compound fertilizer, fly ash, bituminous coal, coke, lignite, Ling U.S. sand, gold, red mud, clay, Kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, muddy green rock, leaf wax rock, shale, purple rock, Diego rock, basalt, gypsum, graphite, insulation material, etc. 

Firstly, raw material is crushed by jaw crusher to the size required, then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff are carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set,s airflow system is closely sealed up and circulated under condition of negative and positive pressure. 

Protection Cover Ring Device Equip with protection cover ring device to prevent materials directly contact roller shaft, that shaft not wearing easily, the protection device can stop partial dust enter in shaft, which prolong shaft service time.

Elastic connection device The elastic fixing part between main machine and classifier, reduced the vibration and noise of raymond mill, and prolong the equipment lifetime.
