Process Flow

  1. Raw Material Selection: High-quality raw materials, such as high-chrome steel or ceramic, are carefully selected based on their composition and properties.

  2. Forming: The selected raw materials are then formed into spherical shapes using precision molding techniques or hot rolling processes.

  3. Heat Treatment: The formed balls undergo heat treatment processes, including quenching and tempering, to optimize their hardness and mechanical properties.

  4. Grinding: The heat-treated balls are precisely ground to achieve the desired size, shape, and surface finish, ensuring uniformity and consistency.

  5. Quality Control: Rigorous quality control measures are implemented throughout the manufacturing process to ensure compliance with specifications and standards.

  6. Packaging: The finished mining process balls are carefully packaged to prevent damage during transportation and storage, ensuring they reach customers in optimal condition.

Application Fields

  1. Mining Industry: Used in grinding circuits for ore processing, including gold, copper, iron, and other minerals.

  2. Cement Industry: Employed in cement mills for grinding clinker and other raw materials to produce cement.

  3. Chemical Industry: Utilized in chemical processing applications, such as grinding pigments, catalysts, and specialty chemicals.

  4. Power Plants: Applied in coal pulverization processes within power plants for efficient coal grinding and combustion.

  5. Construction Materials: Used in the production of construction materials, including ceramics, refractories, and glass.
