But for the productivity of the ball mill, the productivity increases with the increase of the hardness of the ball in a certain range, but when the hardness exceeds a certain range, the productivity of the mill decreases. When the hardness of grinding media ball is too …
Wear Resistant Ball Mill Balls, 20mm - 150mm Grinding Balls For Ball Mill Keywords : Grinding Media Balls, Steel Balls Port : Tianjin/Qingdao/Shanghai
A hardness and structure gradient is usually viewed as undesirable because of faster wear of softer constituents. But the hardness gradient can be exploited to manipulate the ball size distribution of the ball charge to produce better mill grinding capacity and lower ball consumption than is obtained using a ball with harder interior metal.

Surface hardness may only result in a few hours of good performance while linear hardness will produce consistency throughout the balls' deployment. The specific ball design will balance hardness and toughness according to the milling targets in the operational plan.
4/11/2017· In the previous article we considered the method for determining the bulk weigh of new grinding media. Determination the grinding balls bulk weigh directly operating in a ball mill becomes necessary on practice. It is done in order to accurately definition the grinding ball mass during measuring in a ball mill and exclude the mill overloading with grinding balls possibility
The balls have a lot of excellent properties such as higher hardness good abrasive resistance together with a good surface finish and small dimensional allowance after scientific heating treatment as one type of grinding media it can be widely used in ball mill grinding systems of mines cement building materials and chemical industries etc.
Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals. AISI steel grinding balls for ball mill applications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95.

Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm. According to different chromium content, the grinding ball can be divided into three kinds, namely low, medium and high chromium balls. The hardness of relevant balls are HRC≥45, HRC≥50 and HRC≥58 respectively, with diameter of 6 mm to 140 mm.
Silicon Carbide Balls are very high-cost grinding media that are used for milling same materials (silicon carbide ball to mill silicon carbide materials) to avoid contamination. They are only available in 5mm,10mm, 15mm and 20mm sizes. They are a special order item.
Ball Mill Overview. Ball mill is a common grinding machine. It is also the key equipment in grinding industry. Ball mill is suitable for grinding various materials with different hardness and humidity. That's because it has two kind of grinding modes, dry process and wet process.
