How To Choose The Material of Crusher Accessories for Copper Ore Crushing

This question is very accurate and directly related to the crushing efficiency and the service life of accessories! The core conclusion of material selection for copper ore crusher accessories is: with wear resistance and impact resistance as the core, combined with ore hardness, accessory stress type and working conditions, high manganese steel, high chromium cast iron or hard alloy materials are preferred.

Core selection principles

Matching ore hardness: Copper ore (sulfide copper ore, oxide copper ore, etc.) has a moderate to hard hardness and needs to be matched with high wear-resistant materials.

Adaptation of accessory stress: Extrusion accessories (jaw plate, lining plate) focus on toughness and wear resistance, while impact accessories (plate hammer, hammer head) focus on impact resistance and wear resistance.

Balancing cost and lifespan: Do not blindly pursue high priced materials, choose the most cost-effective option based on crushing output and maintenance frequency.

Common accessories and recommended materials

1. Extrusion accessories (jaw plate, lining plate, cone crushing wall)

High manganese steel (ZGMn13): extremely strong toughness, able to withstand ore extrusion deformation, suitable for medium hard copper ore, high cost-effectiveness.

High chromium cast iron+high manganese steel composite material: The surface layer is high chromium wear-resistant, and the inner layer is high manganese steel impact resistant, suitable for high hardness copper ore.

Applicable scenarios: Core extrusion components of jaw crushers and cone crushers.

2. Impact accessories (plate hammer, hammer head, impact plate)

Hard alloy (WC Co): With extremely high hardness and top-notch wear resistance, it is suitable for impact crushing of high hardness copper ore.

Wear resistant alloy steel (such as NM450, NM500): Balancing impact resistance and wear resistance, suitable for continuous crushing of medium hard ores.

Applicable scenarios: Impact components of impact crushers and impact crushers.

3. Auxiliary wear-resistant accessories (screen plate, liner)

Polyurethane: Wear resistant and elastic, suitable for fine screening or wet material crushing, reducing clogging.

Medium carbon alloy structural steel: balancing strength and wear resistance, suitable for auxiliary components that can withstand moderate loads.

Key points for adjusting working conditions

High hardness copper ore (such as high silicon content): Hard alloy or high chromium composite materials are preferred to avoid rapid wear of accessories.

Wet material/high mud content: Choose anti adhesive polyurethane or surface treated wear-resistant steel to reduce scaling.

Continuous high-intensity operation: Choose high manganese steel or alloy steel with good fatigue resistance to extend its service life.
