Abstract

The invention discloses a sand grinder for grinding powder materials by using a wet method. The sand grinder comprises an engine base and a grinding cylinder body, wherein the grinding cylinder body is fixed on the engine base, and a grinding shaft is arranged in the grinding cylinder body; a right cylinder cover is arranged at the right end of the grinding cylinder body, and a grinding sleeve is arranged on the inner wall of the grinding cylinder body; the left part of the grinding shaft is fixed on a bearing seat through a deep groove ball bearing and a cylindrical roller bearing, and the bearing seat is fixedly connected with the engine seat through screws; a mechanical seal mechanism is arranged in the middle of the grinding shaft, axially positioned through a left pressing plate and a right pressing plate on the two sides, and radially positioned through a middle pressing plate; the working chamber of the grinding sleeve and the lubricating chamber of the bearing seat are divided through the mechanical seal mechanism; a plurality of grinding discs are arranged at the right part of the grinding shaft through a flat key and axially positioned through a separation rotor and round nuts, and a filtering hood is arranged between the separation rotor and the right cylinder cover; the left end of the grinding shaft is connected with a big belt wheel, and an included angle A is formed between the left end face of the grinding disc and a vertical direction. The sand grinder has the characteristics of high grinding efficiency, small particle size of micro powder, economic security and convenience in operation.

Description

technical field [0001] The invention relates to a sand mill and a sand mill method, in particular to a sand mill and a sand mill method for wet grinding powder. Background technique [0002] Grinding equipment is an important processing equipment in coatings, chemicals, abrasives, pharmaceuticals, food and other industries. Most of them are developed based on ball mills. It's not the same as a sand mill. The types of sand mills mainly include vertical stirring sand mills, horizontal disc sand mills, and horizontal pin pin sand mills. [0003] The vertical mixing sand mill is characterized by the use of the bottom screen separator and the principle of rod grinding, which has special effects and can better process materials. The disadvantage of the vertical sand mill is that it takes up a lot of space and consumes a lot of energy. The horizontal disc sand mill uses a disc and dynamic rotor centrifugal separator. The horizontal rod-pin circulating sand mill adopts the rod-p...
