Embodiment Construction

[0006] An embodiment is described in detail below: the slurry from the previous process is pumped into the bottom of the peeling grinder by a pump, and it is ground from bottom to top through three stages. The slurry passes through the screen between the layers. Smaller than the grinding body, larger than the diameter of the particles in the slurry, three stages of circular grinding with different ratios are carried out in the same vertical cylinder, and the same spindle drives three mutually isolated grinding sections. The first grade of grinding body is 12kg of zirconia grinding body, 25kg of ceramic grinding body, and 63kg of glass grinding body; the second grade of grinding body is 15kg of zirconia grinding body, 30kg of ceramic grinding body, and 55kg of glass grinding body; The gradation of the three-stage grinding body is 20kg of zirconia grinding body, 35kg of ceramic grinding body, and 45kg of glass grinding body; the grinding time of the slurry at each level is fed ba...

Abstract

The invention discloses a coal-measure hard kaolin wet method stripping monocular tertiary circular grinding method, the process of which is as follows: ground paste coming from an upper working procedure is thrown into from the bottom of a stripping grinding machine by a pump, is processed by the three-level grinding from bottom to top; the grinding and retention time of material at all levels is controlled by overflowing pipes at all levels; the three-level circular grinding with different mixture ratios is carried out in the same vertical cylinder; a switch of valve gate at all levels is automatically controlled by a computer; grinding bodies at all levels of the three-grinding comprise zirconia grinding bodies, ceramic grinding bodies, and glass grinding bodies. In the premise of not adding the energy consumption, the method increases grinding efficiency and is characterized by adjustable grain diameters.

Description

technical field [0001] The invention relates to a single cylinder three-stage circular grinding method for wet stripping of hard kaolin from coal series, in particular to one of the important unit methods in the total production process of hard kaolin from coal series. Background technique [0002] At present, the wet flaking and grinding method of coal-based hard kaolin at home and abroad is an important unit production process of coal-based hard kaolin. Through wet flaking and grinding, the expected maximum particle size of the material appears within a certain range, and then for The next unit chemical reaction process provides the best reaction environment. The current traditional method is the single-cycle wet flaking method, and the grinding body gradation is not variable. When the feed concentration is stable, the grinding particle size of the material cannot be adjusted, which in turn affects the chemical reaction effect of the next unit process. Contents of the in...
