Artificial Sand Grinding Mill Cost

Free customized solution

It is well known to the local contractor that the artificial sand crushers in India Tamilnadu are very popular. The artificial sand produced by proper machines can be a better substitute to river sand. The sand should be sharp, clean and course. The grains should be of durable material. The grain sizes must be such that it should give minimum voids. The presence of clay and silt retards the setting of the cement and makes the mortar weaker and the walls or the slab leaks and holds dampness. SBM will offer the artificial sand grinding mill with low cost in Tamilnadu.

Artificial Sand Grinding Mill

Artificial sand grinding mill

Artificial sand fine grinding mills with low cost in Tamilnadu have improved in design and efficiency in recent years, allowing major opportunities for treatment of materials where liberation to grind sizes below fifteen microns are required. The successful development of the artificial sand grinding mill which has produced equipment capable of grinding the larger tonnages which exist in mineral processing operations, to product sizes below ten microns.

Gravity is the driving force to move the grinding media in ball mills. The mill body usually is a slowly rotating cylindrical or conical drum in horizontal arrangement. Mill dimensions reach up to 25 meters length and 13 meters diameter. The mill drum is wear protected with hard steel or ceramic liners. The same materials are used for the grinding media, which usually have a size of 20-100 mm. Some ball mills for very fine mineral products can be operated with relatively small media in the range of 10-12 mm. Tests with even smaller balls show, that there is a limit in the stress intensity at 4-6 mm media size. Grinding of coarser particles is not possible anymore. And, if the balls are too small, they do not have enough energy to destroy the layers of fine particles sticking at the drum walls and at the media surface.

At the critical speed, the balls are centrifuged to the drum walls and the grinding effect gets lots. Typical rotation speeds are in the range of 60-80% of the critical speed. A high speed level effects a cataract-motion of the balls, which has a high portion of impact stress. The grinding mechanism shifts to a higher portion of shear stress if the mill rotates slower and the motion changes to a cascade-type.
