The chromium content is less than 3%, the hardness is less than 48HRC, and the unit price is lower.
Anhui Chengxin cast grinding balls factory provides high quality low chrome grinding balls. For small size grinding balls, we have 20mm grinding ball for example in the range Φ4mm-80mm.
Low chrome grinding balls serve as essential grinding media in industries such as mining, cement production, and thermal power generation. These balls are used in ball mills to pulverize raw materials into fine powders or to blend materials effectively. Compare to high chrome grinding balls, with a chromium content of 1% to 3%, low chrome grinding balls are less expensive than their high chrome counterparts, offering a budget-friendly option while maintaining adequate hardness and wear resistance for specific applications.
Made primarily from cast iron or steel, low chrome grinding balls are alloyed with chromium to improve durability and hardness. Additional elements like carbon, manganese, and silicon enhance their mechanical properties, providing good toughness and impact resistance. The lower chromium content reduces manufacturing costs, making these balls an economical choice for applications where extreme wear resistance is not critical.
Low chrome grinding balls are widely used in ball mills to process materials like cement clinker, coal, and ores. They are particularly effective in less abrasive grinding environments or where cost control is a priority. For instance, in cement production, these balls are often employed in initial grinding stages where high wear resistance is less essential.
Affordability: Lower chromium levels reduce production costs, making these balls a cost-effective choice for budget-conscious industries.
Sufficient Hardness: They provide adequate hardness for many grinding tasks despite their lower chromium content.
Resilient Toughness: The alloy mix ensures resistance to impact and stress, preventing cracking or breaking during operation.
Ready Availability: These grinding balls are widely available, ensuring easy access for various industrial needs.
