Product Description

thermal insulation balls refractory balls in ceramics
Introduction 
Refractory ceramic balls are made from industrial alumina and other raw refractory materials, and processed by mixing, shaping and firing .It has properties of.Refractory ceramic balls can be used as support and covering packings for catalyst in shift converter, reformer, hydro converter, desulfurizer, and methanator, and can also be used as packings in hot blast heater and heat transformer in iron and steel industries.

2. Features:
 Saina grinding media is characterized by:
(1)Higher density;
 (2)Higher hardness;
 (3)Higher wear resistance;
 (4)Higher grinding efficiency. 
3. Application:
 (1)Used in high speed stirred grinding mills;
 (2)Ball mills as abrasive media for ceramic raw materials;
 (3)Glaze materials in ceramic factories, cement factories, enamel factories;
 (4)Used in glass work, owing to the excellence of high density, high hardness,
and high wear rate. During the abrasive/grinding processing, ceramic balls will not
 break up, they will not pollute the grinding material as well;
 (5)The mix and crush procedure of ceramics, glass, glaze and frits, chemical  and plastic industries.

4. Method of Application:
 (1)Used in wet grinding method:
 A. Final Assembly of ball in ball mills a total volume of 55%.
 Empirical formula: M=3.14*R2*D*L*25%/1000
 (Note: M= charged alumina ball quantity number of added alumina balls
D= alumina ball density(g/cm3)
D= alumina ball density (g/cm3) density of alumina ball
R= radius of ball mill 
RADIUS r = radius of ball mill ball mill
L= length of ball mill 
Length l = length of ball mill ball mill)
For a new installation of ball mill, loading specifications and dimensions of
 the ball depends on the size and weight of the ball mill.
B. Increase volume of ball = Initial amount of ball*Wear rate*Grinding time

(2)Used in dry grinding methods:
 Dry grinding is widely used in mining, ceramics, powders and other industries.
 Wear of grinding media for split industry pollution of raw materials, we developed 
the dry grinding ball of low toughness, wear, solves the grinding media of
 widespread pollution problems of raw materials.
 Dry grinding with grinding ball ratio depends on the raw material of hardness 
and the grinding of rough.
