Structure of Raymond grinding Mill
1. The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing 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 from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant.
Working principle of Raymond grinding mill
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.
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.
1.Higher effciency than ball mill.
Compared with other mils , it's capacity increase by 10~20% under the same power condition. And compression force of rollers to material improve 800~1200 kg under the force of high pressure spring.
2.Extremely fine powder be produced.
The coarse size of final product can be 0.613 mm (30 mesh), the common size is 0.033mm (425 mesh) ; some fine size can reach 0.013mm (1000 mesh ).
3.High pressure and clean operating working shop.
Extreme pressure suspension mill meets the requirement of national dust-dump standard without environmental pollution.
4. Smaller working land and high technology.
Raymond mills are high-effciency closed-circuit and recycled micro-power equipment , which are used in chemical engineering , building material, cement and soon.
