Embodiment 1

[0014] Example 1: Such as Figure 1-3 As shown, the composition of a three-dimensional swing high-energy ball mill is as follows:

[0015] The motor (1) is installed on the motor bracket (17), and the speed of the motor (1) is controlled by changing the output voltage using a frequency converter; multiple shock absorbers (11) are installed between the mounting plate (9) and the bottom plate (10) , the ball mill tank frame (15), the driven wheel bracket (16), and the motor bracket (17) are all installed on the mounting plate (9); Two adjustable feet (12) are installed on the bottom of the outer cover (13);

[0016] The driving wheel (2) of the motor (1) is installed on the shaft sleeve, and the driving wheel (2) is connected with the driven wheel (4) through the timing belt (3); the two bearing seats are installed on the two ends of the gantry bracket (16). On the stand plate, the driven shaft (5) passes through and is installed in the bearings in the two bearing seats, and...

Abstract

The invention provides a three-dimensional oscillating high-energy ball mill. The three-dimensional oscillating high-energy ball mill is novel and unique in structure, stable, reliable and high in efficiency by adopting the one-machine two-tank structure. When small arms rotate by one circle, ball-milling balls in ball-milling tanks complete the reciprocating shock motion from left to right, from front to back and from top to bottom, namely the three-dimensional reciprocating oscillating shock motion once; the higher the rotation speed of a driven shaft is, the higher the frequency of shock completed in unit time is; the greater the included angle alpha is, the higher the shock speed is, and the higher the grinding efficiency is. Because the ball-milling tanks are installed horizontally, fixed bottom surfaces are avoided in the rotation process, the upper bottom surfaces, the lower bottom surfaces and the walls of the ball-milling tanks are grinding surfaces, and therefore the grinding efficiency is improved, and the problem that partial materials sink to the bottoms is well solved. Existing ball mills do not have the function of adjusting the vibration amplitude. According to the three-dimensional oscillating high-energy ball mill, the rotation speed can be adjusted through a frequency converter; by adjusting the included angle between the small arms and the axis line, the vibration amplitude can be adjusted, and both the speed and the force of grinding can be adjusted. By using the three-dimensional oscillating high-energy ball mill, high-quality powder materials can be obtained.

Description

technical field [0001] The invention relates to a three-dimensional swinging high-energy ball mill, which belongs to the technical field of powder material preparation. Background technique [0002] Ball mill is the key equipment for crushing and grinding materials. It is widely used in building materials and chemical industries, especially in the field of powder material preparation. The main machine of the ball mill includes a circular ball mill jar, a motor, a power transmission system, and a rotating part that carries the ball mill jar and maintains it. The ball mill tank is made of steel plate or ceramics, and contains processing materials and ball milling balls. When the motor drives the ball mill to rotate, due to the effects of inertia, centrifugal force and friction, the balls are brought to a certain height, and then they are thrown down due to their own gravity, and the falling balls are like projectiles inside the ball mill. The materials are crushed and groun...
