Abstract
The invention discloses a scattering process of a high-pressure roller grinding material cake. The scattering process adopts three times of scattering, specifically, the first time of scattering adopts a jaw crusher for dry-type scattering, the second time of scattering adopts a spiral ore washer for wet-type scattering, the third time of scattering adopts a single-layer vibrating screen for screening and scattering, undersize products and overflow of the spiral ore washer are combined for subsequent wet-type coarse grain magnetic separation and tailing discarding, and oversize products are returned to a high-pressure roller mill for remilling. According to the scattering process of the high-pressure roller grinding material cake, the dry-wet combined scattering process is adopted for the first time, the high-pressure roller grinding material cake is scattered sufficiently, and the scattering effect is good; the spiral ore washer is applied to high-pressure roller grinding material cake scattering for the first time, the combined effect of cutting, rolling and loosening of the spiral ore washer on materials is achieved, and the spiral ore washer has the advantage of being large in processing capacity; and the selected jaw crusher, the selected spiral ore washer and the selected single-layer vibrating screen are conventional equipment with mature technology and high processing capacity, and the industrial application prospect is good.
