6.What's the process -- Flint Pebbles

The raw material is from silica mine,not river pebbles

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

• Our pebbles are from mountain,first we use explosive mining,and put the rocks into the ball mill for grinding 6-8 hours,make them to become round shape,then screen the similar size,and finally package them into the bags.

• If you need river pebbles,we can supply also.

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

1).Hardness

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

2).Whiteness

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

3).Cleanness

The surface of 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.

9.Which industries can grinding media be applied to?

Ceramic industry ( Tiles, Sanitaryware, Tableware,Porcelain)

Glass Industry

Electronic Industry

Quartz Industry

Cement industry

Chemical Industry(painting,pigment)

10.The Size of silex lining bricks

Usually,the thickness for sidewall is thinner than body.

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

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

1).Length:200-350mm;Width:150-220mm;Thickness:130-140mm;140-150mm;160-180mm;180-200mm for drum/body of ball mill
2).Length:200-350mm;Width:150-220mm;Thickness:120-130mm; 130-140mm;140-150mm;160-180mm;180-200mmfor sidewall of ball mill
