Control of the feeding speed of the Raymond mill

The control of the feeding speed of the new Raymond mill is very important, which is related to the grinding efficiency and particle size of the entire mill. In order to ensure the normal operation of the Raymond mill, reduce the failure of the mill and improve the quality and efficiency of the mill, the uniform and appropriate amount of feeding is the basis for ensuring the optimal load operation of the mill to improve the efficiency, and it is necessary to monitor the load of the mill at any time to prevent the phenomenon of jamming and idling.

After the material is crushed to the required particle size, the material is sent to the storage hopper by the elevator, and then the material is uniformly and continuously sent into the main grinding chamber of the Raymond mill by the vibration feeder, due to the centrifugal force during rotation, the grinding roller swings outward, presses tightly on the grinding ring, and the blade scoops up the material between the grinding roller and the grinding ring, and achieves the purpose of crushing due to the rolling of the grinding roller. The fine powder after material grinding is brought into the analyzer for sorting with the circulating wind of the blower, and the fine and coarse material falls back to the regrinding, and the qualified fine powder enters the finished cyclone powder collector with the air flow, and is discharged through the powder pipe, that is, the finished product. In the Raymond grinding room because there is a certain amount of moisture in the ground material, heat generation during grinding, water vapor evaporation, and the pipe interface of the whole machine is not tight, the external gas is sucked in, so that the circulating air pressure increases, to ensure that the Raymond mill mill mill works in the negative pressure state, the increased air flow is discharged into the dust collector through the residual air pipe, and is purified and discharged into the atmosphere.
