Global Mining Equipment Selection Guide: Recommendations for Primary, Secondary and Tertiary Crushing
Mining equipment selection is critical to improve production line efficiency, control costs and ensure finished product quality in mining and ore processing around the world. Different working conditions, ore hardness and discharge requirements require different primary, secondary and tertiary crushing equipment. Based on rich experience in overseas mining projects, Shanghai Dongmeng provides this professional selection guide for global customers to quickly match the most suitable mining crushing equipment combination.
Recommended Primary Crushing Equipment
Primary crushing is the first stage of ore processing, mainly for large raw ore, requiring large feeding opening and high pressure resistance.
Jaw crusher is the top choice in the industry. It features solid structure, large feeding capacity, strong compression resistance, stable operation, low failure rate, easy maintenance and economic cost.
Application: Large open-pit mine raw ore processing, quarry raw material pretreatment, primary crushing of various high-hardness ores, widely used in global primary crushing.
Recommended Secondary Crushing Equipment
After primary crushing, stones enter secondary crushing to further reduce particle size and optimize shape.
Impact crusher is preferred for medium-hardness ore with good shaping effect and uniform discharge. Standard cone crusher is recommended for high-hardness ore with large capacity, wear resistance and continuous heavy-load operation.
Application: Secondary processing of aggregate, classification of mining materials, road engineering stone processing.
Recommended Tertiary Crushing Equipment
Tertiary crushing produces high-grade fine stone and manufactured sand with strict requirements on discharge precision and uniformity.
High-efficiency cone crusher or vertical shaft impact sand maker is preferred for high-quality construction aggregate and artificial sand. The finished product size is controllable and meets international engineering standards.
Application: High-grade building material processing, fine aggregate production, sand production line, ore fine separation.
Complete Equipment Matching by Ore Hardness
- High-hardness ore (granite, basalt, iron ore): jaw crusher + cone crusher + fine cone crusher, durable and stable.
- Medium-low hardness ore (limestone, bluestone, shale): jaw crusher + impact crusher, more cost-effective.
Equipment Type by Operation Site
Fixed long-term mining area: stationary complete production line with large output and high continuity.
Scattered or remote mining area: mobile integrated crushing plant for on-site processing and flexible transition, saving transportation cost.
Equipment Specification by Capacity Demand
Small mine (below 1000 tons per day): small and medium-sized standard crushers.
Large-scale mine (thousands to tens of thousands of tons per day): large industrial crushing host with complete feeding, screening and conveying equipment.
