Hoë slytasie-onderdeelkoste: Aggressief, unoptimized crushing mechanisms result in premature wear of mortars, sterf, en skoene, leading to high recurring spare parts expenses.
Limited Flexibility for Variable Ore Hardness: Fixedspeed systems struggle with fluctuations in feed material, causing either underprocessing or equipment overload.

Is jou operasie op soek na 'n robuuste, proven solution to create a consistent, optimal feed for your gravity separation or leaching circuits while controlling capital and operational expenditure?

2. PRODUK OORSIG

The modern heavyduty stamp mill is a purposebuilt primary crushing system designed for the reliable reduction of goldbearing quartz ore and hard rock feed material. It serves as a critical first stage in mineral liberation, preparing ore for secondary milling or direct gravity concentration.

Operasionele werkvloei:
1. Voer Inleiding: Runofmyne (ROM) ore is fed into a sealed hopper, regulating flow onto the stamp shoe.
2. Cyclic Percussive Crushing: Meganies opgehef swaar seëls (camshaft or hydraulic) drop onto the ore bed contained within a hardened mortar box.
3. Grootte Klassifikasie & Ontslag: Gebreekte materiaal gaan deur 'n geperforeerde skermplaat aan die basis van die mortelboks. The screen aperture defines the maximum product size.
4. Pulp Handling (Opsioneel): Water can be introduced to create a slurry discharge for direct transport to subsequent wet processing stages.

Toepassingsomvang & Beperkings:
Ideaal vir: Primary crushing of quartz veins, hard rock gold ores, and sulphidebearing materials. Geskik vir mediumskaalse bedrywighede (50500 TPD), modular plant designs, and regions with limited grid power availability.
Beperkings: Nie ontwerp vir fyn maal nie; product size is typically 10mm to 20mm. Less effective for clayrich or highly abrasive ores without modification. Requires firm foundation due to dynamic loads.

6. TOEPASSINGSSCENARIO'S

MidScale Hard Rock Myn, Wes-Afrika | Uitdaging:A remote site with unreliable grid power required a robust primary crusher with low maintenance complexity and the ability to handle highly variable quartz vein material.| Oplossing:A threestamp mill system powered by a dedicated diesel generator set was installed as the plant's primary crushing module.| Resultate:The operation achieved consistent 12mm product at 120 TPD. Velddata toon a 22% reduction in weekly maintenance hours compared to the previous jaw crusher setup, directly lowering flyin technician costs.

Swaartekrag Konsentrasie Plant, Suid-Amerika| Uitdaging:A plant using centrifugal concentrators needed increased gold liberation at the coarse crush stage to improve recovery of freemilling gold without committing to full fine grinding.| Oplossing:A stamp mill was installed ahead of the existing ball mill circuit to generate more fractured fines (2mm) suitable for direct gravity capture.| Resultate:The modified circuit saw a quantifiable increase in coarse gold recovery at the primary stage by approximately 18%, reducing gold losses to tailings from the subsequent milling circuit.
