The invention discloses a vertical sand mill. The vertical sand mill comprises a cylinder, a driving mechanism and a screening mechanism, the cylinder is provided with an inner cavity, one end of thedriving mechanism is rotatably arranged in the cylinder in a penetrating mode and stretches into the inner cavity, the screening mechanism is arranged on the outer wall of the driving mechanism in a sleeving mode, and the screening mechanism and the inner wall of the cylinder are arranged in a spaced mode; and the screening mechanism and the driving mechanism form a first flow pass in an enclosedmode, the screening mechanism and the cylinder form a second flow pass in an enclosed mode, a first via hole and a second via hole are formed in the screening mechanism, the first flow pass and the second flow pass communicate through the first via hole and the second via hole, and the diameter of the first via hole is different from the diameter of the second via hole. According to the technicalscheme, a grinding medium in the grinding process can orderly flow in a flow field together with ground particles with different diameters, the grinding medium and materials are separated, the particles with different sizes are graded, thus the discharged ground particles are uniform in size, and the grinding effect is improved.
Description
technical field [0001] The invention relates to the technical field of sand mills, in particular to a vertical sand mill. Background technique [0002] Sand mill is the most effective equipment for preparing ultrafine particles, mainly divided into two types: horizontal and vertical. However, the grinding flow field of the existing vertical sand mill is disordered, and the classification effect is not obvious, so that the particle size distribution of the discharged product is wide, and the grinding effect and efficiency are not good. Contents of the invention [0003] The main purpose of the present invention is to provide a vertical sand mill, which aims to allow the grinding medium and abrasive particles of different diameters to flow in an orderly manner in the sand mill flow field during the grinding process, so as to realize the separation of the grinding medium and the material and The graded grinding of particles with different diameters makes the size of the disc...
