Abstract
The invention discloses a method for improving the discharge efficiency of a gypsum crusher. The method comprises an equipment pretreatment process and a raw material fluidization treatment process, wherein the equipment pretreatment process comprises the following working procedures that before feeding, an auxiliary A is adopted to coat a feed port and a discharge port of the gypsum crusher, andthe auxiliary A is prepared by dissolving graphene oxide in a mixed solution of ethanol and dimethylacetamide; and the raw material fluidization treatment process comprises the following working procedures that 1) desulfurized gypsum is added into raw-material gypsum, and full mixing and homogenizing are performed to obtain a homogenized raw material, 2) the homogenized raw material and an auxiliary B are mixed, and are mixed through a double-roller mixer, then the raw material fluidization treatment process is completed, and the auxiliary B is prepared from fly ash glass beads, hectorite clay, kaolin, methyl cellulose ether, sepiolite and an organic solvent. According to the method, crushing of the large gypsum can be completed, gypsum powder finished products with small particle sizes also can be obtained through crushing, meanwhile, the labor intensity is reduced, the working environment is improved, and the discharge efficiency of the crusher is improved to the greater extent.
Description
technical field [0001] The invention belongs to the technical field of gypsum processing, in particular to a method for improving the discharge efficiency of a gypsum crusher. Background technique [0002] Gypsum is a monoclinic mineral, based on CaSO 4 2H 2 The natural ore with O as the main component has extremely rich reserves in our country. Gypsum is a versatile industrial and building material that can be used in cement flocculants, gypsum building products, model making, medical food additives, sulfuric acid production, paper fillers, paint fillers, etc. Natural gypsum generally cannot be used directly. It is usually crushed by a crusher and then processed into gypsum powder for utilization. [0003] At present, the gypsum crusher is facing many problems in the process of crushing gypsum. For example, desulfurized gypsum has a high content of adsorbed water, high humidity, and strong viscosity, which brings many difficulties to feeding, discharging, and use. To so...
