Ball-milling mechanical device

Abstract

The invention discloses a ball-milling mechanical device. The ball-milling mechanical device comprises a base, a motor, a speed reducer and a box, wherein supporting legs are respectively arranged at four corners of the base; the motor is fixed on the base and is connected to one end of the speed reducer; the other end of the speed reducer is fixedly connected with one side of an upright column; the other side of the upright column is fixedly connected with the box; an air hole is formed in the top end of the upright column; a discharging plate is arranged at a position where the upright column is connected with the box and is connected with a discharging cavity; the discharging cavity is connected with a collecting cover; a material throwing hole is formed in a position where the upright column is connected with the discharging cavity; and the box is connected with a feeding opening through an air flow speed control device. The ball-milling mechanical device is simple in structure, is connected with components such as the motors through the couplings, has certain effects of damping, buffering and improving dynamic property, and is relatively high in stability; meanwhile, a water absorbing layer and a heat absorbing device are arranged in the box; the service life of equipment is prolonged; and moreover, by an air flow speed control device, speed of air flow can be controlled flexibly, and production efficiency is improved.

Description

technical field [0001] The invention relates to a ball mill mechanical device. Background technique [0002] The ball mill mechanical device is the key equipment for crushing the material after it is crushed. It is widely used in cement, silicate products, new building materials 52555, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation and glass ceramics and other production industries. Various ores and other grindable materials are used for dry or wet grinding. At the same time, ball mills are suitable for grinding various ores and other materials. They are widely used in mineral processing, building materials and chemical industries. They can be divided into dry and wet types. A grinding method.

Problems solved by technology

[0003] The ball mill is composed of the main parts such as the feeding part, the discharging part, the grinding part, the transmission part (reducer, motor), etc. The box is inlaid with a wear-resistant liner, which has good wear resistance, and the inner liner is removable. Its working principle is: select according to the particle size of the grinding material, and the material is loaded into the box by the feed shaft of the ball mill. When the ball mill is running, the ball is attached to the liner of the box due to inertia, centrifugal force and friction. It is taken away by the box, and when it is brought to a certain height, it is thrown down due to its own gravity. The falling ball crushes the material in the box like a projectile, and then it is discharged by the discharge plate, but It is difficult to control the airflow speed of the traditional ball mill mechanical device, which makes it difficult to grasp the size of the crushed particles, and the airflow contains moisture, which will cause certain corrosion to the machine body and reduce the service life of the equipment
