The grinding ceramic ball uses abundant local bauxite resources as main raw material. Its main processing is ingredients, grinding, milling (pulping, mud), molding, drying, firing etc.. It uses advanced temperature control technology and fully automatic dry isostatic press moulding & rolling forming, and finally is sintered through high-temperature gas roller kiln. It is widely used as a grinding media. And its strength and wear resistance is 30% higher than domestic similar products because of a unique technique of our factory.

(1) The product is widely used in ball mills, pot mills, vibrating mills, tower mills etc. for fine grinding equipments. It characterizes of high density, good hardness, good wear resistance, low wear loss, low breakage, less pollution, and uniform internal structure. It is widely used in ceramics, cements, enamel, chemicals, paint, pigments, mining and mineral processing industries.
(2) The product adopts roll forming or isostatic pressing, with a large specific gravity, which can greatly improve the grinding efficiency and reduce the grinding time, effectively increase the effective volume of the ball mill and increase the added amount of the grinding material.
Product is made of rolling forming or isostatic pressing molding. Its high density can greatly improve the grinding efficiency, reduce the milling time, increase the effective volume of the ball mill, and increasing the feed quantity of tile raw material
(3)Its low wear loss can greatly extend its working life. Its grinding efficiency and wear resistance are much better than ordinary pebble or natural pebbles.

FACTORS AFFECTING ACTUAL WEAR LOSS:
1. The quality of the grinding media
2. The ratio of the grinding media
3. The type and speed of the ball mill
4. The hardness and fineness of the feed material.

To grind 1MT tile body material, need about 4-5 kg flint pebble. While a 40MT ball mill only need to add 50-100 KG of Alumina ceramic ball per day after the mill is fully loaded.


HOW TO CALCULATE THE WEAR LOSS:

The mill pot is made of polyurethane with inside diameter 200mm, inside length 220mm. Put 4 kg grinding media into a Polyurethane pot, add 4L water, run the pot mill at a speed 80 revolutions per minute, and let the grinding media to grind themselves in the pot. Weight the loss of the grinding media after 24 hours self grinding. The wear loss is how many gram is lost from one kg of grinding media in one hour self grinding.

HOW TO FILL THE BALL MILL:

1. Large feed material use large grinding ball, small feed material use small grinding ball.
2. Smaller grinding ball get finer grinded particles.
3. You only need to fill the largest ball after the first filling of grinding ball, because the grinding balls inside the mill become smaller after grinding.
4. The filling of grinding ball should be not less than 51% of the volume of ball mill.

THE DATA NEED BEFORE FILLING THE BALL MILL:

1. The loading weight of the ball mill.
2. The inside diameter and length of the ball mill.
3. The motor power (kw) of the ball mill

BALL FILLING RECOMMENDATION:

Initial filling ratio for wet ball mill: The large ball should fill 30% of volume of the ball mill, the middle ball take 40%, and small ball take 30%. The wet ball mill smashes the feed materials mainly by grinding rather than impact. So it should be appropriate to reduce the quantity of large grinding ball, and use more middle and small grinding balls to get better grinding effect. The above filling ratio is not suitable for dry grinding process.
