Chemical, building materials, coatings and other industries, superfine calcium carbonate, talc, dolomite, barite and other non-metallic mineral.
Input size: 10-20mm
Simple and reliable operation:Limit device for preventing the direct contact between grinding roller and grinding table, to avoid the severe vibration of the mill caused by the collision between roller and tables； With hydraulic roller turning-out device, the grinding roller can be turned out of the machine completely to ensure enough maintenance space,which replace and repair easy-wear parts easily in a short time
High grinding efficiency:High grinding efficiency and low energy consumption, saving 40% -50% power consumption compared to ball mill.Special structure design of grinding roller and grinding table, large diameter of grinding roller, large grinding area, hydraulic automatic pressure device.
Stable product quality:The material stays in the mill only for 2-3 minutes, and pollution of the finished product is small； The chemical composition and fineness of the product can be quickly determined and corrected, and the quality is stable.The product has a narrow particle size distribution, uniform particle shape, and good fluidity.
Low overall investment cost:It integrates crushing, drying, grinding, powder selection and conveying into one, with simple process flow and compact layout.Small footprint, can be arranged in the open air, low construction cost.
Energy efficient:Adopt fully automatic control system, can realize remote control, easy to operate.
Grinding roller bearings are lubricated with forced thin oil, longer bearing life;Using an independent oil station，and there is an automatic protection system for oil pressure and oil temperature, which makes the whole set of equipment safe and reliable;Use hydraulic control system to apply and control its force on materials and pressure can be adjusted automatically according to the change of the grindability of the material;The roller sleeve and table lining are made of special materials and have a long service life.
Environmental protection:The whole system is operated under negative pressure without dust overflow，and grinding roller grinding table does not directly contact during the grinding process, so the noise of whole system is low.
The main motor drives the millstone to rotate through the reduction box, meanwhile, the air flow gets into the mill through air intake. The materials come out of the screw feeder and fall on the center of the millstone, and then they will move from the center to the edge of the millstone under the affect of centrifugal force. When they move across the grinding zone, they will get grinded by the rollers.
