OEM Fabrication & Machined Components
SinoField Machinery supports RFQs for large welded mining feed hoppers, ore hoppers, transfer chutes, surge hopper sections, and loading or discharge structures used in crushing, screening, conveyor, quarry, and aggregate processing lines.
Product boundary
This page is for buyers sourcing a fabricated hopper or transfer chute from drawings, site dimensions, worn-part photos, or plant layout requirements. The RFQ should confirm capacity, inlet and outlet interfaces, liner requirement, material handled, welding scope, coating, transport size, and destination before quotation.
Failure modes and control points
Mining feed hopper quotes depend on plate thickness, structural ribs, wear liner design, inlet and outlet geometry, and the working condition at the transfer point.
A hopper with the same outside size can require a different fabrication route when the liner type, bolt pattern, inspection scope, or transport split changes.
For replacement projects, site photos are useful, but drawings or measured interface dimensions are needed before final factory review.

Third-party inspection is available when required for standard products or custom production orders. Buyers may arrange the inspector directly, nominate a specific inspection agency, or ask us to coordinate with a suitable provider.
Inspection fees, re-inspection fees, report charges, timing, and inspection scope are confirmed and covered by the buyer before order or shipment.
Buyer questions
Photos can start the review, but drawings, overall dimensions, inlet and outlet sizes, liner details, material handled, and quantity are needed before a reliable quotation.
Yes. Wear-resistant steel, ceramic, rubber, PU, or other liner options can be reviewed when the material handled, impact condition, bolt layout, and replacement method are defined.
Plate thickness, welding workload, liner type, coating, inspection requirement, trial assembly, packing split, and oversized transport planning all affect lead time.

Final price, samples, lead time, payment terms, and compliance details are confirmed manually after factory review.
