Industrial Grinding Mills
LUM Grinding Mill
Fine powder production is a business of microns. A LUM Grinding Mill reduces crushed feed — calcium carbonate, gypsum, barite, talc, bentonite, slag, coal gangue or clinker — to a controlled fineness between roughly 80 and 2500 mesh, and does it at an energy cost per tonne that decides whether your product is competitive.
HAMAC supplies the MTW European-type trapezium mill for larger capacity and higher classification accuracy, and the YGM high-pressure suspension mill for mid-range output with excellent fineness control. Both integrate feeding, grinding, classification, dust collection and packing into a closed negative-pressure circuit.
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 LUM Grinding Mill
Negative-pressure operation
The whole circuit runs below atmospheric pressure, keeping the plant clean and safe.
Turnkey engineering
We supply layout, power distribution, dust collection design and commissioning as one scope.
High classification accuracy
Cage classifiers cut fines cleanly, narrowing particle size distribution for premium products.
Wear-resistant grinding parts
High-chromium alloy rollers and rings extend service life on abrasive materials.
Energy-efficient drive
Optimised gear-box ratios and balanced rotors reduce kWh per tonne of finished powder.
Integrated packing
Valve bag packers and jumbo bag stations complete the line so no secondary handling is needed.
Technical Parameters
Indicative ranges for standard configurations. Final values are confirmed against your project requirements.

Typical Applications
Field experience across our export markets shows a clear pattern of applications.
Coal gangue and slag processing
Supplementary cementitious material for blended cements
Bentonite and industrial minerals
Drilling mud, foundry binders and pelletising agents
Gypsum and plaster operations
Calcined gypsum used in board manufacturing and plasters
Ceramic and refractory raw materials
Fine body preparation with tight particle control
Barite and talc grinding
Weighting agents and cosmetic-grade powder production
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 LUM Grinding Mill
What fineness can I achieve for my product?
Most industrial fillers run between 200 and 1250 mesh; we recommend a laboratory test.
How do I choose between MTW and YGM?
MTW suits larger capacity and harder feed above roughly 20 t/h; YGM is economical mid-range and excels in very high fineness applications.
Do you test my material before quoting?
We recommend sending 20-30 kg of sample; we perform a laboratory grind test and report achievable fineness and capacity.
Is dust collection effective enough for plant hygiene?
Yes — pulse-jet collectors with the sealed conveying design keep working areas compliant with occupational exposure limits.
What is the wear-part life?
Grinding roller and ring sets typically run 2,000-4,000 hours depending on feed abrasiveness.
