limestone ball mill is for milling the sand material of aerated concrete.
Aerated concrete is made from the raw materials of sand(fly ash), cement, lime gypsum (anhydrite), aluminium powder and water.
As the material of aerated concrete, the precisely measured sand and water should be fed into the limestone ball mill for grinding and mixing. Through this, the raw sand is processed into sand slurry.Once the grinding process is finished, the sand slurry is pumped into sand slurry tanks for storage.
In the process, the slurry density and grinding fineness of the sand slurry should be exactly controled.
