Example Embodiment

[0029] To describe the present invention, the dispersion process of a high pressure roller fabric of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] Depend on figure 1 As shown in the principle of the scattering process of the present invention, the relief process of a high pressure roller fabric cake of the present invention adopts the following steps:

[0031] 1) First dry scatter

[0032] The high pressure roller mill of the maximum cake is given to the PE-150 × 250A jaw crusher for the first dry dispersion, adjusting the drain of the jaw crusher to discharge the granularity ≤ 20mm, and the first Sub-drying products;

[0033] 2) Second wet dispersion

[0034] The second wet dispersion was carried out in a 240 × 2000 spiral washing machine for the first dry dispersion product, which obtained a spiral washing machine overflow, a spiral washing machine.

[0035] 3) The third screen is screened

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...
