Raymond Mill

Raymond Mill is a kind of powder grinding machine with air inlet, air outlet and a feeding port in the middle part. It is suitable for all kinds of pulverized coal making and mineral powder grinding. Compared with the ball mill, it has higher efficiency, lower power consumption, a smaller area and less investment.

What It Is Applied To

Raymond mill is suitable for inflammable or nonexplosive materials whose Mohs scale of mineral hardness is lower than 9.3 and humidity is below 6%, such as barite, calcite, potassium feldspar, limestone, talc, white stone, gypsum, etc. in addition, it also can be applied to calcium carbonate crushing and processing, gypsum powder processing, power plant desulfurization, non-metallic mineral powder, coal powder making, etc., and its product size can be arbitrarily adjusted within the range of 40-400 mesh.

How It Works

When the machine begins to run, the transmitting device drives the central shaft to rotate. The material to be ground enters the machine from the feeding hole on the side of the hood. The plum blossom frame at the upper end of the shaft is connected with the grinding roller device on the frame to form a fulcrum, and the lower end of the frame is equipped with a blade system. Due to the centrifugal force casued by the rotating process, the grinding roller that is on the grinding ring swings out, so that the blade sends the material to the gap between the roller and the ring, achieving the purpose of grinding the material by the grinding roller.
