1. PYNPUNT GEDREWE OPENING

Bestuur jy goudherwinningsbedrywighede wat deur inkonsekwente deurset belas word, oormatige instandhoudingstyd, and unpredictable operating costs? Legacy crushing and grinding circuits often struggle with hard rock ores, leading to suboptimal liberation and gold losses in tailings. Die uitdagings is kwantifiseerbaar: unplanned stoppages for liner changes and mechanical repairs, hoë energieverbruik per ton verwerk, and the constant labor required for manual operation and monitoring. These factors directly erode your profit margin. Is your current mineral processing equipment delivering the reliable, doeltreffend, and costeffective performance required in today’s market? The solution lies in a purposeengineered ODM stamp mill designed for modern gold mining operations.

2. PRODUK OORSIG

This product is a heavyduty ODM (Oorspronklike ontwerpvervaardiger) stamp mill engineered for the primary crushing and coarse grinding of goldbearing quartz rock and other ores. Its operational workflow is a proven, mechanically robust process:
1. Ore Feeding: Runofmyne (ROM) ore is fed into a enclosed mortar box.
2. Verpletterend & Maalwerk: Meganies opgehefde seëls (heavy iron rods) word vrygelaat om op die erts te val, repeatedly pulverizing it through impact.
3. Misvorming: Water is introduced to create a slurry of crushed material.
4. Ontslag: The slurry passes through a perforated screen plate at the end of the mortar box, verseker beheerde deeltjiegrootte.
5. Goud herstel: The discharged slurry flows to downstream processes like sluices or amalgamation plates for gold concentration.

Application scope includes primary comminution for small to midscale hard rock gold mining operations, loodsaanlegte, and historical site reprocessing. It is particularly suited for vein material where freemilling gold is present. A key limitation is its relatively coarse grind compared to ball mills; it is typically deployed as a primary unit ahead of finer grinding or as a standalone solution where very fine liberation is not required.

6. TOEPASSINGSSCENARIO'S

SmallScale Hard Rock Mine Expansion

Uitdaging:A West African operation using manual crushing faced bottlenecks limiting plant expansion.Their challenge was adding reliable primary crushing capacity without complex infrastructure or highly skilled operators.
Oplossing:The implementation of a modular threestamp ODM stamp mill as the new primary crusher,fed directly by ROM ore from the mine portal.
Resultate:Behaal konsekwente deurset van 2 tons per hour.Freed up labor previously dedicated to manual crushing.Gold recovery improved due to more uniform feed size delivered to the concentration sluices.

Historiese uitskot-herverwerkingsaanleg

Uitdaging:A contractor reprocessing old tailings in North America needed coarse liberation of locked gold particles without overgrinding already fine material.Conventional jaw crushers were creating excessive fines,and ball mills were too energyintensive.
Oplossing:A twostamp ODM mill was installed as a tertiary grinder.The adjustable stroke allowed gentle but effective cracking of conglomerates without pulverizing the entire feed.
Resultate:The project met target liberation rates while reducing specific energy consumption by over 20% compared to the ball mill alternative,increasing project net present value.
