Dry type ball mill for mineral separation

Abstract

The invention discloses a dry type ball mill for mineral separation. The dry type ball mill for the mineral separation comprises a cylinder. A first lower seat, a second lower seat and a large gear are installed on the cylinder. The first lower seat and the second lower seat are located on the two sides of the large gear correspondingly. One side of the first lower seat and one side of the secondlower seat are rotationally connected with a first upper cover and a second upper cover correspondingly through hinges. The inner portions of the first upper cover and the second upper cover are bothinternally provided with moving clamping grooves. The inner portions of the first lower seat and the second lower seat are both provided with fixing clamping grooves. According to the dry type ball mill for mineral separation, locating rings, a first bin partition plate, lock grooves, fixing bolts, bolt holes, lock rods, reset springs and a second bin partition plate are arranged, when the bin partition plates are replaced, the fixing bolts on the upper covers and the lower seats are disassembled first of all, the lock rods on the two sides of the bolt holes lose limitation after the fixing bolts are disassembled, under rebounding of the reset springs, the lock rods shrink into the bin partition plates, so that limitation between the bin partition plates and the locating rings is eliminated, the bin partition plates are in the movable state, and then bolts between the upper covers and the lower seats are unscrewed through a tool.

Description

technical field [0001] The invention belongs to the technical field of ball mills, and in particular relates to a dry ball mill for ore selection. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. This type of grinding machine is filled with a certain number of steel balls in its cylinder as the grinding medium. It is widely used in cement, silicate products, new building materials, In industries such as refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation, and glass ceramics, dry or wet grinding of various ores and other grindable materials is carried out. Ball mills are suitable for grinding various ores and other materials and are widely used. For mineral processing, building materials and chemical industries, it can be divided into dry and wet grinding methods. [0003] However, the existing dry-type ball mill divides the mill cylinder into two sections through the partition p...
