AI Technical Summary
Traditional ball milling systems suffer from poor acid resistance and rapid wear when processing acidic media, especially in the pre-leaching process of ore, where existing carbon steel equipment cannot meet the requirements of acidic environments.
The design incorporates an integrated stainless steel frame and anti-corrosion rubber layer, combined with a triple-sealed acid-resistant and anti-corrosion layer and acid-resistant and wear-resistant materials. It modifies the feeding mechanism, ball mill, and cylindrical screen to enhance the equipment's wear and corrosion resistance, and facilitates maintenance through its detachable and segmented design.
It significantly improves the durability and stability of the equipment in acidic media environments, reduces maintenance costs, enhances ball milling efficiency and product quality, and reduces equipment downtime due to malfunctions.
