Continuous roller type kaolin mashing system

Abstract

The invention provides a continuous roller type kaolin mashing system which is stable in slurry concentration and cannot excessively grind sandy materials. The system comprises a continuous feeding mechanism, an inclined feeding pipe and a horizontally-placed mashing roller. An inlet of the mashing roller is connected with the bottom of the inclined feeding pipe, and a wear-resisting lining plateis arranged on the inner wall of the mashing roller. Multiple rubber shoveling plate strips are arranged on the inner wall of the mashing roller in the axial direction, an outlet of the mashing rolleris a through hole of a plum-blossom-shaped structure, the through hole of the plum-blossom-shaped structure comprises an inner circular through hole, and multiple semicircular hollowed-out openings are formed in the edge of the inner circular through hole in an annular array manner. The outlet of the mashing roller is connected with a sand discharging screen and an impurity discharging grid screen, the sand discharging screen and the impurity discharging grid screen are coaxially arranged and are both of cylindrical structures, the diameter of the end of the impurity discharging grid screen is the same as the diameter of the inner circular through hole, the diameter of the end of the sand discharging screen is at least larger than or equal to the diameter of the outermost end of the semicircular hollowed-out openings, an impurity conveying belt conveyor is arranged at an outlet of the impurity discharging grid screen, a sand conveying belt conveyor is arranged at an outlet of the sanddischarging screen, and a slurry conveying groove is formed in the bottom of the sand discharging screen.

Description

technical field [0001] The invention relates to the technical field of beneficiation and processing equipment for non-metallic ore, in particular to a continuous drum-type kaolin pounding system. Background technique [0002] In the deep processing of kaolin beneficiation, kaolin raw materials are fed into the working pool of the pulping machine through the feeder, water and dispersant are added, and after mixing, they are stirred at high speed in the pulping machine to break up and make pulp. The purpose of pulping is to make kaolin The raw ore is fully dispersed and separated from sandy minerals and impurities to prepare high-concentration kaolin slurry, while removing large-grained sand and impurities to prepare kaolin slurry with stable quality for the next operation. [0003] The existing kaolin ramming system is a paddle strong stirring, breaking up ramming, intermittent production. Because the kaolin in kaolin raw ore has a fine particle size, less than 325 mesh, the...

Problems solved by technology

Intermittent production is greatly influenced by human factors, and the degree of automation is low. It is impossible to effectively control the production process, which is not conducive to the deep processing of the subsequent selection process, a
