Raymond mill is a kind of crushing equipment which is widely used in non-metal mining industry and it has the following advantages such as stable performance, widely suitable range, simple structure, easy operation and huge capacity. Our MRX powder grinding machine has many other properties besides those above, such as high productivity, fine process, precisely grade, energy saving and environmental protection. 1. Products are improved greatly. It possesses the capacity to produce superfine powder lower than 1250 item, from input of raw materials (1-20mm) to the output of 800-1000 items of superfine powder. 2. Productivity: output per powder grinding machine is increased by 30% than common Raymond mill. 3. High efficiency and energy saving, its power consumption decreases greatly and creates remarkable economic benefits. 4. Clean production environment, no dust pollution inside and outside of the workshop, which improve operating condition of workers and reduce discharging loss of fine powder. 5. Wide application: experiments proved that all materials that Raymond mill can process pendulum grinder also can do.
