Raymond Mill
The origin and development of raymond mill
After many years of practice and improvement, the structure of raymond mill from the professional manufacturer Zenith is getting perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional mill.
Raymond mill has almost several tens of years history, and the Shanghai Zenith raymond mill has the same age with the first one all over the world.
Currently, the most popular raymond mill in the leading position are on the basis of Newell Company and occupies 70% market share. Raymond mill’s production and the development has closely related to the development of scrap industry. Firstly, most raymond mills are used for handling with some frivolous material, but with the deepening of understanding and the superiority of the crushing steel, all kinds of raymond mills are developed quickly and used wider and wider. Even to the entire scrapped cars and household appliances, processed with appropriate conveyor and sorting equipment, the composition of scrap broken lines can be easily finished ,so it is no need to dismantle of scrapped cars and household appliances and it is easily to product and process automatically to get pure crushed steel, non-ferrous metals and non-metallic materials available.
How Raymond Mill works?
Firstly, raw material is crushed by jaw crusher to the size required, and 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 of raymond mill 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 is 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 airflow system is closely sealed up and circulated under condition of negative and positive pressure.
