1. What we do?

We are a manufacturer of ceramic grinding media.

Our flint pebbles and alumina balls are widely used to grind the clumpy materials to fine powder in a ball mill.

Silex blocks and alumina lining bricks are used as mill liners to protect the machine and lengthen the use life of the ball mill.

2. What information do you need to prepare if you want to get an exact quotation from us?

1) For Flint pebbles and alumina balls, you need to tell us your required size(diameter) and quantity.

2) For silex blocks and alumina lining bricks, you need to kindly tell us your ball mill size (Diameter and Length) and the thickness of bricks you prefer. Then we will calculate the weight you need for one ball mill and give you a reasonable price.

3. Process -- Flint Pebbles

The raw material is from silica mine, not river pebbles

Mining -- Sorting raw rock -- Manual Cutting -- Grinding -- Screening -- Packing

4. Important index to evaluate quality --- Flint Pebbles

1). Hardness

Our flint pebbles have a higher silica content of 99.31%, and the density is 2.66g/cm3, so it decides the pebbles with hardness of 8 months and better wear resistance.

2). Whiteness

The whiteness after firing reaches the standard for tableware because our pebbles contain a low iron of 0.018%.

3). Cleanness

The surface of the pebbles will have a little powder, but it won’t influence the raw materials in the ball mill

Because the powder is made from the pebbles during the process of grinding.

5. Size of silex blocks

Usually, the thickness of the sidewall is thinner than that of the body.

Length and width usually are a range, different sizes assure the blocks to be stably installed on the ball mill.

The sum of the width for all rows is equal to the perimeter of the ball mill, and the sum of the length for all columns is equal to the length of the ball mill.

1).Length:200-400mm;Width:150-220mm;Thickness:150-180mm for drum/body of ball mill

2).Length:200-400mm;Width:150-220mm;Thickness:120-140mm for sidewall of ball mill

Remark: other sizes can be produced according to your requests.
