Problems solved by technology

After working for a long time, a large amount of dust will accumulate inside the screen of the ball mill, which needs to be cleaned. When cleaning, water is generally sprayed from the outside of the screen to the inside for flushing, but the sieve hole of the ball mill is generally small in diameter, and the water flow should not enter the inside of the screen during flushing. A large amount of

Example Embodiment

[0012] In order to facilitate the understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the screen of the ball mill of the present invention includes a screen cylinder body 1, which has a cylindrical structure. The cylinder is provided with a plurality of screen holes for screening materials. The two ends of the screen cylinder body 1 are respectively It is the feed port 2 and the discharge port 3. The boring after being milled by the ball mill enters the screen cylinder body 1 from the feed port 2. After the fine materials are discharged from the screen holes, the coarse materials are output from the discharge port 3. The screen holes on the mesh cylinder body 1 are flanged from the inside to the outside. After the ordinary screen holes are washed, the water flow and the dust are easily blocked in the screen holes, and the flanging can guide the water flow a...

Abstract

The invention discloses a ball mill sieve comprising a sieve barrel body. Sieve holes are distributed all over in the sieve barrel body. The two ends of the sieve barrel body are provided with a feedinlet and a discharge outlet correspondingly. A water pipe extending from the feed inlet to the discharge outlet is arranged in the middle of the sieve barrel body and communicates with a water tank.The water pipe is provided with a plurality of water spray structures. Orientations of the water spray structures are different. The water pipe is provided with a valve controlling water flow quantity. The water pipe is sleeved with a sleeve capable of moving horizontally. The water spray structures are installed in the middle in the ball mill sieve and spray water outwards from the inside of thesieve, and sewage discharge is facilitated by impulsive force of water flow. The water pipe can rotate, the washing range during water spray is wider, and the washing effect is better. The sieve holesare provided with outward flanges, and sewage can be discharged conveniently. The water pipe is further sleeved with the sleeve, the water pipe and the water spray structures are sheltered after washing, and the condition that powder enters the water spray structures during operation of a ball mill is avoided.

Description

technical field [0001] The invention relates to the field of ball mills, in particular to a ball mill screen. Background technique [0002] The sieve of the ball mill is set at the discharge port of the ball mill, and the material is screened after the ball mill completes the grinding, and the fine material is screened out from the sieve hole. After working for a long time, a large amount of dust will accumulate inside the screen of the ball mill, which needs to be cleaned. When cleaning, water is generally sprayed from the outside of the screen to the inside for flushing, but the sieve hole of the ball mill is generally small in diameter, and the water flow should not enter the inside of the screen during flushing. A large amount of water resources will be wasted during flushing. Since the flushing is carried out externally, the dust in the screen receives the external momentum, which is not suitable for sewage discharge; the water flow after flushing will accumulate inside...
