Embodiment 1

[0057] see figure 1 , figure 2 , image 3 with Figure 4 , The ball mill mixing device of this embodiment includes a drum 2, a plurality of grinding balls 16, a driving device 2, a device seat 1, a cleaning mechanism, and a stirring mechanism.

[0058]The drum 2 is inclined, and the inside of the drum 2 is divided into a plurality of grinding bins 9 sequentially along the direction of the drum 2's downward inclination through the partition board 8, and the plurality of grinding bins 9 are used for layered grinding of materials. Moreover, at least one opening is provided on the edge of each partition 8 , and a filter net 22 is arranged in each opening. The mesh diameter of each filter screen 22 decreases successively along the direction in which the drum 2 inclines downward. One side of each filter screen 22 is correspondingly provided with a funnel 19, and each funnel 19 is positioned at the side of the corresponding filter screen 22 along the direction of inclination of ...

Embodiment 2

[0071] Please combine Figure 5 and Figure 6 , the ball mill mixing device of this embodiment adds a scraping mechanism on the basis of Embodiment 1. When the drum 2 is performing abrasive operations, due to gravity, the material will form a certain angle at the angle between the partition 8 and the inner wall of the drum 2. Accumulation, and agglomeration will occur due to extrusion, and agglomerated materials are inconvenient for grinding. The scraping mechanism is used to scrape up the material accumulated on one side of the filter screen 22 when the drum 2 rotates. The scraping mechanism includes a plurality of extension rods 17 corresponding to a plurality of partitions 8 respectively. One end of the extension rod 17 is provided with a scraper 15 close to the inner wall of the cylinder 2, and the other end of the extension rod 17 is fixedly connected to the inner shaft 11. When the drum 2 rotates, the scraper 15 can scrape up the materials attached to one side of the f...

Embodiment 3

[0075] see Figure 7 , The ball mill mixing device of this embodiment adds another reduction box 27 on the basis of Embodiment 1. Gear box 27 is used for carrying out deceleration transmission to motor one 4, and gear box 27 is positioned at an end outside cylinder 2 through transmission chain one 23 transmission connections of inner shaft 11.

[0076] Wherein, when the motor one 4 starts, the reduction box 27 decelerates the motor one 4 and outputs a larger torque, and then drives the inner shaft 11 to rotate through the transmission chain one 23 . The reduction box 27 makes the force driving the rotation of the inner shaft 11 larger, so that a larger amount of material can be processed.

Abstract

The invention discloses a ball grinding and mixing device. The ball grinding and mixing device comprises a device seat, a rolling drum, a plurality of grinding balls, a cleaning mechanism and a stirring mechanism, the rolling drum is in an oblique shape and internally divided into a plurality of grinding bins in the downward direction of the rolling drum through a plurality of filtering nets in sequence, and the diameter of each net hole of each filtering net is reduced in sequence in the downward direction of the rolling drum; and the multiple grinding balls are divided into a plurality of groups of grinding balls, and each group of grinding balls is distributed in the corresponding grinding bin, the cleaning mechanism includes an inner shaft, a plurality of first extension rods, and a plurality of brushes, the stirring mechanism comprises a plurality of stirring rods and stirring blades. According to the ball grinding and mixing device, by arranging the multiple grinding bins and multiple groups of grinding balls, after a material is put into the rolling drum, the rolling drum rotates, the multi-step grinding can be conducted through the multiple groups of grinding balls, and thegrinding effect is good; and the stirring rods and the stirring blades in the stirring mechanism can fully mix the material, the brushes in the cleaning mechanism can clean up the corresponding filtering nets, and the filtration efficiency of the filtering nets is maintained.

Description

technical field [0001] The invention relates to the technical field of rare earth processing equipment, in particular to a ball mill mixing device. Background technique [0002] Rare earth is the general name of seventeen metal elements including lanthanides, scandium and yttrium in the chemical periodic table. When processing rare earths, it is necessary to crush and mix the materials, so it is necessary to use a ball mill mixing device to mix and mix the materials. Abrasive work. [0003] The existing ball mill mixing device has a simple structure, only adding grinding balls into the drum. On the one hand, the crushing efficiency is not high, and the materials cannot be filtered while crushing, and the filtered materials are re-grinded, while the filter residue remains the same. Continue to crush in the drum; on the other hand, when mixing and grinding materials, the mixing is uneven and the crushing efficiency is low, which is not conducive to improving production effici...
