The cylinder lining plate of ball mill 13 is used mostly based on high-chromium cast liner plate at present, and abrasive media uses Gao Ge mostly
Steel ball or steel forging.In grinding machine operational process, abrasive body strikes the collision on hard liner plate or between abrasive body, can all produce
Raw strong noise.The unit weight of abrasive body is bigger, and the noise of generation is bigger.And non-metal grinding medium ball unit weight is small, only 1.9
~2.2t/m3, it is the 40%~50% of steel ball or steel forging, therefore the ball mill using non-metal grinding medium as abrasive media is crushing
The noise that collision of the abrasive body between the impact of liner plate and material, abrasive body is formed during material is substantially reduced, and is reduced to behaviour
Make the harm of worker and ambient enviroment.
In conclusion the utility model is smaller non-by unit weight by the abrasive media in Vertical Mill pregrinding system in ball mill
Metal grinding media instead of traditional steel ball or steel forging, can improve the grinding efficiency in mill, improve in mill " paste ball " phenomenon,
Finished cement size distribution can be adjusted again, improve cement water requirement.Meanwhile can reduce ball mill noise in the process of running,
Reduce the pollution to finished product.
