Casting iron balls include high chromium balls, medium chromium balls and low chromium balls.
Quality index of high chromium casting ball:
The chromium content of the high chromium ball is 10.0% or more. The carbon content is between 1.80% and 3.20%. According to national standards, the hardness of the high chromium ball must be no less than 58hrc, and the impact value should be greater than or equal to 3.0j/cm2. To achieve this hardness, the high chromium ball must be quenched and tempered at high temperature. At present, there are two methods for quenching high chromium balls in China, including oil quenching and wind quenching. If the test hardness of the high chromium ball is lower than 54HRC, it means that it has not been quenched.
Quality index of medium chromium casting ball
The specified chromium content of the medium chromium ball ranges from 3.0% to 7.0%, and the carbon content is between 1.80% and 3.20%. Its impact value should not be less than 2.0j/cm2. According to national standards, the hardness of the chrome ball should be greater than or equal to 47hrc. In order to ensure quality, medium chromium balls should be tempered at high temperature to eliminate casting stress.
If the surface of the iron ball is black and red, it proves that the iron ball has been tempered at high temperature. If the surface of the iron ball still has the metal color, we can judge that the iron ball has not undergone high temperature tempering treatment.
Quality index of low chromium casting ball
Generally speaking, the chromium content of the low chromium ball is 0.5% to 2.5%, and the carbon content is from 1.80% to 3.20%. Therefore, according to the national standard, the hardness of the low chromium ball should be no less than 45hrc, and the impact value should be no less than 1.5j/cm2. Low chromium balls also need high temperature tempering treatment to ensure quality. This treatment can eliminate casting stress. If the surface of the iron ball is dark red, it indicates that it has undergone high temperature tempering treatment. If the surface is still metallic color, it means that the iron ball has not been tempered at high temperature.
Casting iron balls are usually used in various large-scale mines, cement plants, chemical plants, power plants, quartz sand plants, silica sand plants, etc.

Alumina Grinding Ball Usage:Wet grinding Al2O3(%):92 Hardness(Mohs):9 Grinding media is characterized by: Higher density; Higher hardness; Higher wear resistance; Higher grinding efficiency. SPECIFICATION Application Area Used in high speed stirred grinding mills; Ball mills as abrasive media for ceramic raw materials; Glaze materials in ceramic factories, cement factories, enamel factories; 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 grinded material as well; The mix and crush procedure of ceramics, glass, glaze and frits, chemical and plastic industries. Method of application: 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 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, usually by isostatic molding grinding balls.
