1.The materials that meet the grinding particle size are unloaded into the large silo by the loader. A weighing and metering feeding device (belt metering scale) is arranged under the silo. The device is controlled by a microcomputer and automatically adjusts the feeding amount according to the capacity input parameters.
2.In order to ensure that the mill meets the production standards and reduces the consumption of grinding bodies, a permanent magnetic iron remover is suspended on the feeding belt conveyor to remove metal (physical iron) impurities in the raw materials.
3.This set of grinding scheme adopts a closed-flow (circular flow grinding) grinding process, that is, the mixed powder discharged from the ball mill first enters the powder selection machine for air selection, the fine ash directly enters the finished product warehouse, and the coarse ash returns to the ball mill for secondary grinding, thus forming a closed-loop grinding system.
4.Although the investment in the circle flow grinding system is larger, the fineness (particle size ratio) of the product is uniform, the quality is stable, and the output is much higher than that of the same model ball mill.
