An all-round planetary ball mill directly connected to a geared motor

Abstract

The invention relates to an all-dimensional planetary ball mill with directly-connected speed reduction motors. The all-dimensional planetary ball mill comprises a rack, a planetary motor, a transmission speed reducer, a transmission shaft, a planetary bearing, a rotating stand, milling tanks, a turning motor, a turning speed reducer, a turning shaft and a turning bearing. The planetary motor is fixed on a fixed frame which is fixed at the lower end of the rack, rotated by 90 degrees and shaped like a Chinese character 'zhong', an output shaft of the transmission speed reducer penetrates through a bottom plate seat at the lower end of the rack to be connected with the bottom end of the transmission shaft, the top end of the transmission shaft penetrates through a regular octagon installation platform to be connected with the rotating stand, the milling tanks are fixed on the rotating stand, a main shaft of the turning motor is connected with an input shaft of the turning speed reducer, an output shaft of the turning speed reducer is connected with one end of the turning shaft, and the other end of the turning shaft is connected with the side end of the rack. According to the all-dimensional planetary ball mill with the directly-connected speed reduction motors, the unique structure and principle of the speed reducers are utilized, original additional tension force and eccentric force are reduced, and meanwhile the size can be decreased; therefore, the effects of reducing abrasion, reducing noise and prolonging the service life are achieved.

Description

Technical field [0001] The invention relates to the field of powder grinding machinery, in particular to an omnidirectional planetary ball mill directly connected with a geared motor. Background technique [0002] Ball mill is the key equipment for crushing materials after crushing; it is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, non-ferrous metal beneficiation, glass ceramics and other production industries. Grindable materials can be ground dry or wet; 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 grinding methods; The discharging method is different, which can be divided into two types: continuous and intermittent. [0003] Among them, the omnidirectional planetary ball mill is a style of planetary ball mill. Its characteristic is that the planetary structure revolves and ...

[0003] Among them, the omnidirectional planetary ball mill is a style of planetary ball mill, which is characterized in that the planetary structure is revolving and rotating at the same time, and the whole is turned 360 degrees, so as to achieve a full range of grinding effect; the current omnidirectional planetary ball mill transmission device on the market The motor drives the transmission shaft through the belt device to drive the revolution and rotation of the planetary wheel structure system. Due to the pulling force of the belt, the transmission shaft is subjected to an additional pulling force perpendicular to its axis, which will easily cause the shaft to bend for a long time; the transmission shaft The above bearing is also subjected to a similar force, which seriously affects the life of the bearing; in terms of turning motion, since the motor (located on the same side as the planetary wheel turret and the grinding pot) and the belt device are located on both sides of the turning shaft, the motor and the planetary The weight of the wheel structure and the load system is much greater than that of the belt device, so that there is a large eccentric force during the overturning movement, which will increase the overturning load and the burden on the bearing on the overturning shaft, accelerate wear and tear, and the noise of the equipment is also large; At the same time, the belt is easy to wear, and it will be troublesome to replace the belt
