The main components of the Raymond Mill are a fixed and a rotate grinding roller. The grinding ring is installed on the edge of main unit. When the grinding roller rotates around, it is pressed tightly on the grinding ring due to the centrifugal force, and the blade rotating with the grinding roller scatters the material of the chassis between the grinding roller and the grinding ring, and the material is received between the grinding roller and the grinding ring. Squeeze and grind to break.
In terms of working mode: when the Raymond mill works, the material to be crushed is fed into the machine from the feeding hopper on the side of the machine casing, and the grinding roller hung on the plum blossom frame of the main machine revolves and rotates around the longitudinal axis due to centrifugal force. , The grinding roller swings outwards to compress the grinding ring, so that the blade pushes the material between the grinding roller and the grinding ring for smashing. When the ball mill is working, the material is transferred to the front row bin in the crushing chamber through the transportation device, relying on the stepped and fluctuating liner, the collision, rolling, impact and grinding between the steel balls, and then the powder passes through the discharge grate The plate is discharged and the grinding is completed.
In terms of parts configuration, the ball mill is mainly composed of the feeding part, the discharging part, the revolving part, the transmission part and other main parts, with a wear-resistant liner inside, which has strong abrasiveness, but the disadvantage is that it covers a large area. Raymond mill is mainly composed of main machine, analysis machine, blower, motor, etc. The main machine is mainly composed of frame, inlet volute, blade, grinding roller, grinding ring, cover, etc., covering an area twice as small as a ball mill.
In terms of scope of application: ball mills are mainly used in ore-dressing industries such as cement, new building materials, refractory materials, and non-ferrous metals. Raymond mills are widely used in the milling and processing of various non-flammable and non-explosive minerals with the hardness below 7 and humidity below 6%, such as marble, limestone and dolomite, Its grinding range is better than that of a ball mill. Almost all materials that can be ground in the ball mill are applicable. It has high output, low energy consumption, environmental protection, and its finished products are also better than ball mills. This is why Raymond Mill is more and more popular among ball mill users.
