The product uses advanced structure of similar foreign products, designed and updated on the basis of large-scale Raymond improve. The device is higher than the ball mill efficiency and low power consumption, small footprint, less one-time investment. Grinding rollers firmly in the role of centrifugal force on roller compacted in the grinding ring, so to a certain thickness does not affect the finished product yield and fineness of grinding roller and grinding ring wear. Grinding roller and grinding ring update cycle, thus excluding the centrifugal mill consumable parts replacement cycle short ills. 
 Winnowing air machine is a circular flow of operations within the fan - grinding shell - cyclone - fan, so less than the high-speed centrifugal mill dust, clean, pollution to the environment of the operating workshop.
