After many years of practice and improvement, the structure of the Raymond mill is getting perfect day by day. For low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The series is used in grinding the non-flammable and non-explosive stuff which has the Moh s hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bleaching, bauxite, iron ore etc., the final products change from 613 micron to 44 micron. Through the function of separator and blower, it can meet different customers demand. Technical features of Raymond Mill: 1.
overall machine is vertical structure of space saving and strong systematic. It can be used as an independent production system, from raw material processing to transporting to powder making and packing the rough. 2. Compared with other mills, its passing through rate can be as high as 99%. 3. Gearing of mainframe is equipped sealed gear box and belt belly, drives stability and operates reliably. 4. Main part is made of high quality cast and steel, which ensures the durability of whole plant.
5. Electric control system is centralized controlled, the application is advanced and reasonable, and the automation degree is high. 6. In engineering project: It is an ideal equipment of artificial sand, cusion material, asphalt concrete and cement concrete aggregate making. 7. In mining industry: It is widely used for the first stage ore grinding, que pueden produces adequate ore aims to reduce the high cost ore grinding load.limestone dryer: sand washing machine: Structure of Raymond Mill: 1. The whole plant is a vertical structure of strong systematic characteristic, so it small area Governor. It is an independent production system from crushing of raw material to grinding and packing. 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 from cast steel and 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. Working Principle: 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 tbsp. 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.
