Scattering process of high-pressure roller grinding material cake

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.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a process for breaking up high-pressure roller abrasive cakes, which is particularly suitable for processing magnetite that contains a lot of mud or clay minerals so that the high-pressure roller abrasive cakes are difficult to disperse. Background technique [0002] The high-pressure roller mill has the characteristics of large crushing ratio, fine particle size, high efficiency, low consumption, and can effectively reduce the grinding work index. Since the first high-pressure roller mill in the domestic metallurgical and mining industry was successfully applied in Nanshan Mining Company of Masteel Group, a wave of application of high-pressure roller mills has been set off in China, and very good energy-saving and emission-reduction effects have been achieved. [0003] As we all know, the material is crushed into fine particle products under the strong ext...

Problems solved by technology

However, the application practice of this wet cylindrical material breaker in mines shows that there are still the following problems: First, the processing capacity of the equipment is small and cannot meet the requirements of high-pressure roller mill for large processing capacity. It has not been fully utilized; the second is that the material cake is not completely broken up, and some sticky lumps are not broken up, which affects the subsequent sorting effect
