Product Details
â– Description:
The micro crystalline wear-resistant alumina ball is a premium grinding medium created from high grade materials, cutting-edge molding techniques, and high temperature tunnel kiln calcination. The goods are the most suitable medium for processing mineral powder, glaze, and blanks due to their high density, high hardness, low wear, good seismic stability, and superior corrosion resistance.
In the manufacturing of ceramics, cement, paint, refractories, inorganic mineral powder, and other products, alumina balls are employed as the ball mill's grinding medium.

â– Application:
â— How to optimize the grinding process
-- In the situation of wet grinding
Usually, the total charges of the alumina balls in one ball mil should be not less than 55% of the total ball mill capacity.
Economical Empirical formula of charged alumina ball quantity into ball mill
M=3.14 x R2 x D x L x 25%+1000
Remark M= charged alumina ball quantity (kg)
D=Alumina ball density(g/cm)
R=Radius of ball mill L=Ballillength
-- In the situation of dry grinding
Dry grinding is widely used in mining, ceramics industries, we developed alumina balls performed well on dry grinding situation with much lower wear-loss, it helps solve the problem of materials contamination.
The proportion of the alumina ball for dry grinding depends on the hardness and fineness of the grinder raw material. Generally speaking, CIP formed grinding ball used for dry grinding.
â— Quantity of recharging aluminum balls
Primary ball quantity + Ball wear + Riding time = Recharge quantity
With regard to dry grinding
We produced alumina balls that functioned well in dry grinding situations with significantly lower wear-loss, helping to overcome the issue of material contamination. Dry grinding is commonly utilized in the mining and ceramics sectors.
Generally speaking, CIP produced grinding balls are used for dry grinding. The percentage of alumina balls for dry grinding depends on the hardness and fineness of the grinding raw material.
â— Alumina grinding ball proportion
The proportion of alumina balls for a shiny new ball mill relies on the ball mill's capacity and the fineness of the ground raw materials.
