Abstract

The invention discloses a basket mill. The basket mill comprises a milling basket body, a milling basket bottom connected with the bottom of the milling basket body, a bracket for supporting the milling basket bottom and a spindle, wherein the spindle sequentially penetrates through the milling basket body, the milling basket bottom and the bracket vertically, a centrifugal impeller and a drum are sequentially arranged in the milling basket body from top to bottom, a stirring device is also fixed at the lower end of the spindle, a first milling channel is formed between the drum and the milling basket body, a milling inlet channel is formed above the centrifugal impeller, a first screen is arranged at the upper end of an inner ring of the milling basket bottom, a second milling channel is formed between the first screen and the drum, the first milling channel is communicated with the second milling channel, a third milling channel is formed between the first screen and the spindle, a part of the second milling channel passing through the first screen is communicated with the third milling channel, and a milling output channel communicated with the lower end of the third milling channel is formed in the side surface of the bracket. Therefore, the basket mill has the beneficial effects that the screen is not easy to wear or jam, and the milling efficiency is high.

Description

technical field [0001] The invention relates to a grinder, in particular to a basket grinder. Background technique [0002] Basket mills currently used for wet crushing are composed of a circular basket, a screen for separating materials and grinding media, a stirring device in the basket, and a suction impeller on the main shaft of the stirring device. The basket contains a certain amount of grinding beads. When working, the basket is vertically immersed in the container, and through the rotation of the stirring device, the grinding beads in the basket and the material are repeatedly collided and sheared to achieve the dispersion and refinement of the material. In order to make the material circulate up and down in the container, a suction impeller is arranged on the upper part of the grinding basket. However, since the screen is located at the bottom of the grinding basket, the grinding media will frequently rub against the screen during use, resulting in wear of the scre...
