1. PYNPUNT GEDREWE OPENING

Bestuur jy goudherwinningsbedrywighede wat deur inkonsekwente deurset belas word, buitensporige onderhoudskoste, en suboptimale mineraalvrystelling? Legacy crushing and grinding circuits often create bottlenecks that directly impact your bottom line. Oorweeg hierdie algemene uitdagings:
Onbeplande stilstand: Frequent liner changes and mechanical failures in traditional stamp mills halt entire processing lines, duisende per uur in verlore produksie kos.
Ondoeltreffende Goudbevryding: Inconsistent particle size distribution from worn or poorly calibrated equipment leads to gold losses in tailings, algehele herstelkoerse te verminder.
Hoë bedryfskoste: Oormatige energieverbruik per ton verwerkte erts, coupled with high labor requirements for operation and manual maintenance, winsmarges erodeer.
Skaalbaarheidsbeperkings: Rigid systems that cannot be efficiently tuned for varying ore hardness or target grind size limit operational flexibility.

Is jou operasie op soek na 'n robuuste, reliable comminution solution engineered to maximize throughput and minimize total cost of ownership for primary gold ore processing?

2. PRODUK OORSIG

The Industrial Stamp Mill is a heavyduty, mechanized milling system designed for the primary crushing and coarse grinding of goldbearing quartz ore. It operates on the principle of repetitive dropping of heavy weights (seëls) onto ore fed into a mortar box, fracturing the material through impact.

Operasionele werkvloei:
1. Voer Inleiding: Runofmyne (ROM) ore is consistently fed into the mill’s mortar box via a regulated feed system.
2. Cyclic Percussion: Mechanically lifted stamps are released in a controlled sequence, delivering highimpact blows to the ore bed.
3. Deeltjiereduksie & Misvorming: Crushed ore is combined with process water, creating a slurry that passes through discharge screens at the base of the mortar box.
4. Gravity Separation Feed: Die afgevoerde flodder, now optimally sized, is conveyed to downstream gravity concentration systems (bv., skud tafels, sentrifugale konsentrators).

Toepassingsomvang & Beperkings:
Omvang: Ideal for hard rock gold mining operations processing quartz veins and other brittle ores. Highly effective in remote locations or smallerscale operations requiring mechanical simplicity and durability over ultrafine grinding.
Beperkings: Not designed for fine or ultrafine grinding required for refractory ores. Performance is optimal with ores of consistent hardness; highly abrasive or clayrich feeds may reduce efficiency and increase wear.
