Custom Components for Mining & Mineral Processing Equipment

LANJIAN manufactures custom structural castings, welded frames, housings, transmission components, and wear parts for mining equipment OEMs, mineral processing machinery manufacturers, and bulk material handling system builders. Components are produced to customer drawings for crushing, screening, feeding, conveying, grinding, and heavy mobile equipment.

Scope: Drawing-based component manufacturing for equipment OEM and replacement projects—not complete mining machines.

The Engineering Reality of Mining Equipment Components

Mining and mineral processing equipment must operate while handling abrasive ore, repeated impact, heavy structural loads, continuous vibration, dust, and moisture. In crushers, screens, feeders, conveyors, and grinding systems, these conditions directly affect component wear, structural stability, assembly accuracy, and replacement frequency.

Custom mining equipment components therefore need to be evaluated according to their service position, material contact, load-bearing areas, mating interfaces, maintenance requirements, and required supply condition—not only by part name or overall shape.

Key Operating Challenges for Mining Equipment Components

Mining equipment components do not face the same combination of wear, impact, heavy loads, vibration, and assembly requirements. The appropriate manufacturing response depends on the component function, approved drawing, material requirement, critical interfaces, and required delivery condition.

Abrasive Material Flow

Ore, rock, and bulk materials create continuous and localized wear at crushing, screening, conveying, and transfer points.

LANJIAN SUPPORTS

Wear-resistant castings and replaceable liners manufactured to approved drawings, material grades, hardness requirements, and critical dimensions.

Impact & Heavy Structural Loads

Repeated impact and sustained loads place high demands on frames, supports, mounting areas, and load-bearing interfaces.

LANJIAN SUPPORTS

Structural castings and welded fabrications produced to the approved geometry, material, machining, and applicable inspection requirements.

Vibration & Assembly Alignment

Continuous vibration makes mounting faces, bearing seats, hole patterns, and drive interfaces critical to stable assembly and operation.

LANJIAN SUPPORTS

Cast and fabricated components supplied with machined datums, bearing seats, and mounting interfaces, with critical dimensions verified before delivery.

Maintenance & Component Replacement

Replacement parts must match the correct drawing revision, mating dimensions, installation space, and required delivery condition.

LANJIAN SUPPORTS

Drawing-based replacement components supplied in the agreed condition—from casting or fabrication blanks to finish-machined, surface-finished, or assembly-ready parts.

COMPONENT GUIDE

Custom Components for Mining Equipment Applications

Different mining equipment systems require different combinations of structural strength, wear resistance, machining accuracy, and delivery condition. Use this guide to identify the typical drawing-based components LANJIAN can manufacture for each application. These are examples of our manufacturing scope rather than standard stocked parts.
