Gold Ore Crushing Circuits
A typical gold ore crushing circuit consists of primary jaw crushing, secondary cone crushing and a tertiary crushing stage (cone or VSI crusher) feeding grinding. Screening is applied between crushing stages to control product size and maximize circuit efficiency. The precise configuration depends on ore hardness, feed size distribution and target grind.
For gold mines producing gravity-recoverable coarse gold, WSHT recommends a crushing circuit that avoids over-crushing — to preserve gold particle size for gravity recovery. Where gold is primarily recovered by flotation or leaching, a finer and more consistent crush product is preferred.
Copper Ore Crushing Circuits
Copper porphyry deposits are the classic application for high-capacity crushing circuits. These typically comprise large primary jaw or gyratory crushers, secondary cone crushers in open- or closed-circuit with screens, and tertiary cone crushers operating in closed circuit with screens to produce a consistent feed size for the grinding circuit.
WSHT designs copper ore crushing circuits with high availability, low wear part consumption and careful attention to ore abrasiveness and plant layout.
Aggregate and Quarry Crushing Plants
Aggregate production requires well-graded, cubical products with minimal fines. Typical plant configurations depend on rock type: (1) Hard rock (granite, basalt): jaw + cone + cone + multi-stage screening; (2) Medium-hard rock (limestone): jaw or impact crusher + VSI crusher + screening; (3) River gravel: screening + optional secondary crushing.
WSHT designs aggregate plants with specific focus on product gradation, product shape and low fines generation — all critical to high-value aggregate sales.
Portable and Modular Crushing Plants
For smaller mining and aggregate operations, and for projects requiring periodic relocation, portable and modular crushing plants are an efficient, cost-effective option. WSHT supplies wheel-mounted and track-mounted portable crushing and screening units, as well as containerized modular crushing circuits.
Portable plants reduce civil engineering requirements, shorten project lead times, and offer flexibility for multi-site operations.
Stationary Crushing Plants for Large Mines and Quarries
WSHT designs and builds large stationary crushing and screening plants for major mining and aggregate projects — with capacities from several hundred to thousands of tons per hour. These plants integrate robust primary, secondary and tertiary crushing equipment with multi-stage screening, belt conveyors, dust collection and centralized plant automation.
Engineering focus areas include foundation design, structural steelwork, crusher chute design and dust control — all critical for reliable long-term operation.
