AI Technical Summary
In vertical mills for raw materials, the high moisture content of the raw materials entering the mill and the low temperature of the air entering the mill from the preheater result in poor material flowability on the grinding disc, which causes the main motor current of the mill to be too high, resulting in high power consumption and long grinding time.
Design a grinding disc discharge and material leveling device for a vertical mill for raw materials, including a retaining ring and a scraper fixed on the grinding disc frame. The scraper frame is equipped with a flat plate and a discharge plate. The material is turned over and leveled by the rotation of the grinding disc, thereby enhancing the material flowability.
It improves the flowability of materials on the grinding disc, reduces the power consumption of the raw material vertical mill process, and shortens the grinding time.

[0006] Further, the material scraping frame is provided with four material scraping frames, and the four material scraping frames are arranged at equal angles with the axis of the retaining ring as the center.
[0007] Further, the material leveling plate is an inclined steel plate fixed on the material scraping frame.
[0008] Further, the discharging plate is a V-shaped steel plate, and one end of the V-shaped steel plate is vertically welded to the material scraping frame.
[0009] Further, the bottom of the discharging plate is lower than the material leveling plate.
[0010] Further, an adjusting through groove is vertically arranged on the material scraping frame; further comprising a bottom plate, the discharging plate is fixed on the bottom plate, a corresponding groove is arranged on the bottom plate opposite to the adjusting through groove, and the adjusting through groove and the corresponding groove are tightly fixed by screws and nuts.
[0011] The utility model has the advantages of:
[0012] In actual application, the raw material is turned over by the discharge plate during the process that the mill main motor drives the mill disc to rotate, the material on the mill disc is scraped flat by the material leveling plate, and the flowability of the material on the mill disc is increased; the raw material vertical mill process power consumption is reduced, and the raw material grinding process time is shortened. BRIEF DESCRIPTION OF DRAWINGS
