The ball mill body 1 is rotatably mounted between the two supports 2. A feed hopper 3 is mounted on the right end of the ball mill body 1. A water collecting box 4 is provided directly below the ball mill body 1. A base 5 is fixedly connected to the back of the water collecting box 4. A bracket 6 and a water tank 7 are mounted on the top of the base 5. A first water pump 8 is mounted on the top of the water tank 7. A first pumping pipe 9 is mounted between the input end of the first water pump 8 and the water tank 7. A first connecting pipe 10 is fixedly connected to the output end of the first water pump 8.
