The selfreturning device is located in the revolving part of the mill, and the material forms a selfcirculation in the revolving part of the mill through the selfreturning device, discharging the qualified material from the mill, leading the unqualified material back into the revolving part to participate in the grinding operation. The ball mill adopts a discharge screen similar to the ball mill, and the function of
There are two types of selfgrinding process: dry grinding and wet grinding. Concentrators mostly use wet grinding. The technician pointed out that in order to solve the problem of hardtogrind particles in selfgrinding and improve the grinding efficiency, a small amount of steel balls are added to the selfgrinding machine, which is called semiselfgrinding.

Selfgrinding, semiautogenous grinding machine. Since the use of selfgrinding and semiselfgrinding technology in the 1950s, it has grown into a mature, reliable and continuously applied technology. In the selfgrinding process, the ore larger than 100 mm in the mill acts as a grinding
A semiselfgrinding ball mill for ores, wherein a first belt type transmission machine is connected between a vibration feeding machine and a semiselfgrinding machine, and the materialoutput port of the semiselfgrinding machine is against to a vibration sieve feeding port. The material output port of the sieve downside of the vibration sieve is connected with a sand pump pond.
The working principle of the selfgrinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize.
Ball mill is an efficient tool for grinding medium hardness ore and other materials and widelyused in many industries such mineral preparation, metallurgy, chemical industry, building material, thermal power industry, and etc. There are two grinding ways of the ball mill: The dry process and the wet process.
