Pulverizing equipment

 After the material is crushed to the required particle size by the pulverizer, the material is sent to the storage hopper by the elevator, and then the material is uniformly and continuously fed into the main grinding chamber of the Raymond mill by the vibrating feeder. Due to the centrifugal force during rotation, the grinding roller Swing outwards, press tightly on the grinding ring, the shovel blade scoops up the material to be sent between the grinding roller and the grinding ring, and the grinding roller is rolled to achieve the purpose of crushing. The fine powder after material grinding is brought into the analyzer with the circulating air of the blower for sorting, the coarse material falls back to regrind, and the qualified fine powder enters the finished cyclone powder collector with the airflow and is discharged through the powder outlet pipe. That is the finished product. Because there is a certain amount of water in the material to be ground in the Raymond mill, heat is generated during grinding, the water vapor evaporates, and the pipe connections of the whole machine are not tight, and the external air is sucked in, which increases the circulating air pressure to ensure that the mill is under negative pressure. Working in the state, the increased air flow is discharged into the dust collector through the residual air pipe, and then discharged into the atmosphere after being purified. In the pulverizer, a lower grinding chamber, an upper grinding chamber, a sorting mechanism and a powder discharging mechanism are sequentially arranged on the support of the grinding chamber. A pulverizing rotor is installed on the power shaft that extends into the lower grinding chamber. With liner, the crushing rotor is a dual-fan composite impeller jet rotor. The upper part is the material jet fan, and the lower part is the air jet fan. The material jet fan and the air jet fan share a fan rear plate. The center of the front plate of the material jet fan is the material At the entrance, the material jet fan is surrounded by a discharge port.
