Advantages and Disadvantages of Small Ball Mill

The ball mill is the most widely used grinding equipment in China. The small ball mill is the most commonly used grinding equipment in the mineral processing industry and other industrial sectors. The small ball mill is mainly used to grind coal with various hardness, which is the generator boiler of the thermal power plant and related industrial sector prepares qualified pulverized coal fuels and can also be used in cement plants and other related industrial sectors to grind other materials.
Small ball mill advantages: suitable for dry grinding or wet grinding, smooth running, grinding machine cheap, easy to replace, operating conditions, crushing in the closed body, no dust flying; crushing explosive materials, can be filled with inert gas instead air.
Small ball mill disadvantages: low efficiency, high energy consumption, grinding body and the body of the friction loss is large, and will pollute the product; small ball mill is widely used in hard material crushing, running a strong vibration and noise, foundation.
In view of the ball mill in the production process has such advantages and disadvantages, so the choice of ball mill type, according to the actual situation, as well as their own needs, select the most suitable ball mill.
Small Ball Mill Work Principle:
Materials are put in cylinder through the feed opening and then thoroughly grinded, because the falling course of iron balls and ores can produce huge falling impact and autogenous grinding. The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge opening. Finally, acceptable particles are discharged from the discharge opening. The discharge opening is equipped with a discharge grate, and the ore pulp horizon of discharge opening is low. These two factors prevent ores from being overly grinded, and iron balls from being dismissed.
Small ball mill is essential and widely used for grinding coarse particles.
