Description: How should customers choose vertical roller mill
Group News
Vertical milling equipment and ultra-fine milling equipment are two kinds of milling equipment used for micro-powder processing in daily industrial production. Some customers are easily confused when buying equipment. Shanghai SBM is a professional manufacturer of grinding equipment in China. Now we tell the two kinds of grinding equipment how to choose?Vertical mill is also called vertical roller mill, vertical roller mill, etc. It is one of the ultra-fine mills. This machine can be used to process various stones. The fineness of the finished product is 325 mesh-3000 mesh. It is currently processed in China. Ideal equipment for stone powder.Working principle of ultra-fine grinding equipment: When working, the main motor drives the spindle turntable through the reducer, and the roller pin on the edge of the turntable drives dozens of grinding rollers to roll in the grinding ring raceway. The large pieces of material are broken into small particles by the hammer crusher and then sent to the storage bin by the elevator, and then through the vibrating feeder and the inclined feed pipe, the material is evenly sent to the upper bulk disc of the turntable.The material is scattered to the periphery of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring and is impacted, rolled, and ground by the ring roller. After the three-layer ring process, it becomes powder. The high-pressure fan sucks the outside air by suction Inhale into the machine, and bring the crushed material into the powder separator.The rotating impeller in the powder separator makes the coarse material fall down and regrind. The fine powder that meets the requirements enters the cyclone powder collector with the air flow and is discharged by the discharge valve at the lower part of it, which is the finished product, and the air flow with a small amount of fine dust passes The pulse dust collector is discharged through the fan and muffler after purification.Due to the improvement of the production technology of ultra-fine grinding equipment, the processing fineness can be increased to 3000 meshes, which has completely broken the processing limit of Raymond grinding equipment. The pulse dust collector is used to capture the dust, and the muffler is used to reduce the noise. It has the characteristics of environmental protection and cleanliness, and completely eliminates the disadvantages of high pollution of the Raymond milling equipment.SBM engineers suggest that when customers purchase grinding equipment, they must clearly understand their production needs, especially the processing fineness of the material; if the processing fineness is above 300 mesh, use ultra-fine grinding equipment.
