Embodiment 1

[0015] Embodiment 1, with reference to accompanying drawing, a kind of continuous dry ball milling device comprises ball mill, air classifier 5, cyclone collector 3 and dust collector 2, and air classifier 5 is provided with raw material inlet, fine powder outlet and coarse powder outlet. Powder outlet 6; the bottom of the cyclone collector 3 is provided with a finished powder outlet 4, and the upper part of the cyclone collector 3 is provided with a dust outlet and a powder inlet; the lower part of the dust collector 2 is provided with a dust outlet, and the upper part is provided with a dust inlet. An induced draft fan 1 is connected to the bottom of the side of the collector 2 to help discharge dust;

[0016] The ball mill includes a frame 15 and a cylinder body 13, the two ends of the cylinder body 13 are respectively fixedly connected with a feed pipe 14 and a discharge pipe 9 through end caps, and the feed pipe 14 and the discharge pipe 9 are installed on the machine thro...

Embodiment 2

[0019] Example 2: In the continuous dry ball milling device described in Example 1, an impurity filter 16 is provided in the middle of the automatic conveying pipeline 17 , and an impurity collection device is provided below the impurity filter 16 . When the quartz sand raw material passes through the automatic conveying pipeline 17, impurities such as small stones in the raw material will fall from the impurity filter screen 16 and enter the impurity collection device, thus eliminating the manual process of picking impurities and improving work efficiency.

Embodiment 3

[0020] Embodiment 3, in the continuous dry ball milling device described in Embodiment 1, the feed pipe 14 is provided with a material propulsion thread, and the thread in the feed pipe 14 can spirally push the material into the barrel 13 of the ball mill , to improve the feeding effect.

Abstract

The invention relates to a continuous dry ball milling device. The continuous dry ball milling device comprises a ball mill, an air classifier, a cyclone collector and a dust collector. The ball mill comprises a frame and a barrel body. Two ends of the barrel body are fixedly and respectively connected to a feeding pipe and a discharge pipe by end covers. A front part of the barrel body is provided with a hopper. The hopper is connected to the feeding pipe by an automatic delivery pipe. The discharge pipe of the barrel body is connected to a storage bin. A fine material outlet of the storage bin is connected to a raw material inlet of the air classifier by a pipe. A fine powder outlet of the air classifier is connected to a powder inlet of the cyclone collector by a pipe. A dust outlet of the cyclone collector is connected to a dust inlet of the dust collector by a pipe. The continuous dry ball milling device has the advantages that continuous production is realized; products are obtained by one-step feeding; product quality is stable; production efficiency is high; a production cost is low; product granularity is controllable; particle size distribution is reasonable; large particles and superfine particles are avoided; automatic production is realized; and labor intensity is reduced.

Description

technical field [0001] The invention relates to a dry ball mill, in particular to a continuous dry ball mill. Background technique [0002] The dry ball mill is the key equipment for crushing the material after it is crushed. In the prior art, when manufacturing silica powder, it is processed by multiple intermittent horizontal ball mills. Finally, the discharged materials are manually sent to another ball mill for processing, and finally manually screened and classified. This method has high labor intensity, low work efficiency, high production cost, uncontrollable product particles, and complicated operation procedures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a continuous dry ball milling device with simple structure, convenient use and high production efficiency aiming at the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the f...
