Introduction:
4R series Raymond mill is mainly used for grinding of ore products such as metallurgy, building materials, chemical industry and mining. It can also grind quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, aluminosilicate, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, zircon sand, slag, water slag, cement clinker, activated carbon, dolomite, etc Granite, garnet, iron oxide yellow, bean cake, chemical fertilizer, compound fertilizer, fly ash, bituminous coal, coking coal, lignite, Lingmei sand, chrome oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, maifanite, rhyolite, dolerite, pyrophyllite, shale, amethyst, stromatolite, basalt, gypsum, graphite Processing of various non flammable and explosive mineral materials with Mohs hardness below 9.3 and humidity of 6%.
Working principle:
The working principle of Raymond mill is that the grinding roller is tightly rolled on the grinding ring under the action of centrifugal force, and the material is sent to the middle of the grinding roller and the grinding ring by the shovel blade. The material is broken into powder under the action of the rolling pressure, and then the pulverized material is blown up under the action of the fan, and the material meeting the fineness requirement passes through the analyzer, and the material that fails to meet the requirement is returned to the grinding cavity to continue grinding The material from the separator is separated and collected by cyclone separator. Industrial filter cloth is used to separate the exhaust air and form powder at one time. The machine is mainly used for barite, calcite, potash feldspar, limestone, talc, white stone, gypsum, etc.
It can be used for high and fine milling of hundreds of materials, such as non flammable and explosive mineral products, chemical products, building materials and so on, with a particle size of 40 It can be adjusted within 400 mesh. According to the requirements of different materials, fineness and output, this series of products can be divided into three series of high-pressure micro grinding, high-pressure suspension roller grinding and ordinary Raymond grinding. The whole structure of Raymond mill is composed of main engine, analyzer (powder concentrator), pipeline device, blower, cyclone separator of finished product, jaw crusher, dustpan elevator, electromagnetic vibration feeder and electric motor. The main machine of Raymond mill is composed of frame, air inlet volute, blade, grinding roller, grinding ring, cover and motor.
Advantage:
1. the whole Raymond mill is vertical structure, covering a relatively small area and strong system. It can be used as an independent production system, whether it is from rough processing of raw materials or to powder production and final packaging.
2. compared with other grinding equipment, Raymond machine has a high sieve passing rate and a passing rate of 99%, which is not generally achieved by other grinding equipment.
3. the main driving device of Raymond machine (Raymond Mill) adopts closed gearbox and belt wheel, which is stable and reliable.
4. the important parts of Raymond mill are made of high-quality castings and profiles, with fine and rigorous process, which ensures the durability of the whole set of equipment.
5. the electric system of Raymond mill adopts centralized control, and the grinding workshop can basically realize unmanned operation and convenient maintenance.
