High Efficiency Crushing from HAMAC - a Chinese manufacturer established in 2005. Complete crushing and screening lines from primary jaw to finished aggregate Send your output requirement and get a matched proposal within one working day.
Crushing & Screening Plants
high efficiency crushing
HAMAC sizes every line from the same three inputs: feed size, required tonnage per hour, and the product fractions specified by your mix design. From there we fix the crusher model, the screen deck area, the conveyor widths and the power requirement before a single plate is cut.
A high efficiency crushing turns blasted rock into saleable aggregate. In practice that means a primary crusher that accepts the biggest boulder from the quarry face, a secondary and often tertiary stage that shapes the particles, and screening decks that cut the stream into the size fractions your concrete or asphalt plant actually buys. HAMAC builds each stage — jaw crushers, impact crushers, cone crushers, vertical shaft impact crushers, vibrating screens and feeders — and then integrates them into stationary, modular or crawler-mounted layouts.
Most enquiries we receive start after a fleet problem — a pump that loses pressure on long booms, a mixer whose drum liners wear prematurely, a batching plant whose weighing tolerance drifts. Each of those has an engineering answer, and that answer belongs in the design stage rather than in the warranty claim.
Key Advantages of high efficiency crushing
Diesel-electric freedom
Tracked units run either from the mains or from their own diesel generator when the grid has not arrived yet.
True-stage matching
Crusher chamber profile, eccentric throw and screen deck are matched to each other, so no single stage becomes the bottleneck of the whole high efficiency crushing.
Quick relocation
Modular skid and crawler chassis versions travel without foundation work, cutting mobilisation from weeks to days.
Dust and noise control
Enclosed screen decks, water spray bars and optional bag filters keep the plant within site emission limits.
Spare capacity designed in
Conveyors and screens are sized roughly 15% above nominal so short-term peak demand does not stall the line.
Wear parts you can source
Manganese jaw dies, blow bars, mantle and concave sets use common profiles and are stocked for ten years.

Indicative ranges for standard configurations. Final values are confirmed against your project requirements.

Typical Applications
On typical projects this equipment is selected where output reliability governs the whole schedule.
Construction and demolition waste
Recycled concrete crushed and screened back into road base material
Sand manufacturing
VSI stage producing manufactured sand to replace natural river sand
Railway ballast production
Cubical particle shape and tight grading for track ballast
Mine overburden and ore pre-crushing
Primary reduction ahead of milling circuits
Aggregate quarries
Granite, basalt, limestone and river pebble processed into concrete and asphalt fractions
From Enquiry to Commissioning
Six defined stages, each with named deliverables, so nothing is left to interpretation.
Requirement study
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Scheme design
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
Quotation & contract
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Production & inspection
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Delivery & installation
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
After-sales
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
Frequently Asked Questions about high efficiency crushing
How do I choose between a jaw and an impact primary crusher?
A jaw handles abrasive and high-strength rock up to roughly 320 MPa and gives a low wear cost per tonne, while an impact crusher produces a far better particle shape for concrete aggregate but wears faster on hard or abrasive stone.
How much maintenance does the plant need daily?
Roughly 30 minutes: check lubrication pressures, belt tracking, screen mesh tension and hydraulic oil temperature. Weekly items add oil sampling and bolt re-torquing.
Do you provide installation and commissioning?
Yes — supervision of foundation, assembly, alignment and first start is included, and operator training during commissioning is standard.
Is a mobile plant worth the extra cost?
If your plant moves more than twice a year, or if foundation work is expensive at your site, the crawler or wheeled version usually pays for itself inside two seasons.
Can the plant be upgraded later?
Yes. Conveyors, screen decks and even the tertiary crusher can be added later because we keep the layout modular and reserve structural capacity for it.
