Comparison between cast ball and rolled ball

In recent years, the domestic market is gradually introducing a new type of ball milling ball - hot-rolled ball milling ball, which can be widely used in industries that require grinding machines such as mine dressing plants, thermal power plants, cement plants, and refractory material plants. Hot-rolled milling steel balls are of good quality, high cost performance, and energy-saving and environmentally friendly manufacturing process. At present, they have been widely used by large foreign mining companies and have gradually replaced traditional casting balls. Research on hot-rolled milling steel balls is conducive to environmental protection and energy saving, improving the level of technology, and improving the economic benefits of enterprises.

The disadvantages of pelletizing production process are:

     1. Cast iron, which is the essence of cast balls, meets the requirements of ball milling balls after adding a large amount of chromium.

     2. The cast ball has loose structure, coarse grain, relatively poor wear resistance, poor impact toughness and high breakage rate.

     3. High energy consumption, heavy pollution, high labor intensity and low labor productivity.

     4. The cost of raw materials is high, and the cost of wages is high, especially for small balls below F50mm, the cost is higher.

     Compared with cast balls, hot-rolled steel balls are a brand-new rolling process technology, a technological breakthrough in the ball milling ball manufacturing industry, and are gradually replacing cast balls. Hot-rolled steel balls have the following characteristics:

     1. Hot-rolled steel balls have all the advantages of steel, and become high-quality milling balls after heat treatment.

     2. High production efficiency, large output, mechanized ball rolling production, high degree of automation, no manual production links.

     3. Stable quality, good hardness, hardenability, dense metallographic structure, fine grains, good wear resistance, half of the wear of cast balls, impact toughness as high as 12-35J/cm2, and breakage rate less than 0.1%.

     4. Low energy consumption, no pollution, low labor intensity, and low production cost. In the long run, casting balls will inevitably be replaced by rolling balls.
