The hardness difference between the surface and core of our cast grinding balls is less than 1HRC. The hardness is balanced and the ball consumption is extremely low, making our products the best choice for major mining companies. As a leading cast grinding balls factory, we offer competitive cast grinding balls price without compromising on quality.
After nearly a hundred years of development, the casting steel ball technology has continued to mature and the production equipment has been constantly updated. This will lead to continuous improvement in product quality and more stable performance of the casting grinding steel ball.
All cast grinding balls of our company are produced using automated iron mold sand-coated production lines. The heat treatment adopts GX series push rod type full-fiber heat treatment. The product quality is stable and the customer's use effect is good.
As a reliable cast grinding balls factory, Chengxin strictly implements the ISO9001:2015 quality management system standards, established and improved various quality control standards and process documents, and further improved the quality assurance system of the cast grinding balls. We have set up full-time quality inspectors for every process from raw materials entering the factory to products leaving the factory. Carry out supervision and control, and establish a quality inspection system of workshop self-inspection, quality inspection department sampling inspection, and laboratory final inspection, implement a one-vote quality veto system, and continuously create excellent casting grinding balls.
Grinding balls, typically used in ball mills for ore processing and other grinding applications, are manufactured from various materials tailored to meet specific requirements. Common raw materials include high carbon and chrome steel, valued for their hardness, strength, and wear resistance, with alloying elements like chromium enhancing these properties. Stainless steel is preferred in industries where corrosion resistance is crucial, such as pharmaceuticals and food processing. Ceramic grinding balls, made from materials like alumina or zirconia, offer high wear resistance and chemical inertness, making them ideal for applications where contamination from metallic media is undesirable. Although less common today due to lower wear resistance, cast iron grinding balls were traditionally used in some applications. Additionally, specialized applications may employ other alloyed materials or composites designed for specific needs such as enhanced hardness, toughness, or corrosion resistance.
