1. PYNPUNT GEDREWE OPENING

Are you managing a gold processing operation where inconsistent throughput, hoë instandhoudingskoste, and unpredictable recovery rates are eroding your profit margins? Operational challenges with your comminution circuit directly impact your bottom line. Oorweeg hierdie algemene probleme:
Oormatige stilstand: Unplanned stoppages for liner changes or mechanical repairs can cost thousands per hour in lost production.
Inefficient Grinding & Bevryding: Poorly sized ore particles from inadequate stamp action lead to suboptimal gold liberation, trapping valuable material in tailings and reducing overall recovery.
Hoë bedryfskoste: Rising energy consumption per ton of ore processed, coupled with frequent replacement of wear parts, drives up your costperounce.
Skaalbaarheidsbeperkings: Inflexible equipment that cannot adapt to varying ore hardness or feed grades complicates plant expansion and process optimization.

Hoe bereik jy konsekwent, costeffective ore reduction for maximum gold recovery? The solution lies in moving beyond standard machinery to purposebuilt, heavyduty equipment engineered for relentless performance.

2. PRODUK OORSIG

The Certified Stamp Mill is a heavyduty, mechanized milling system designed for the primary crushing and grinding of goldbearing quartz ore. It utilizes the controlled, repetitive impact of weighted stamps (skoene) to pulverize ore fed into a mortar box, liberating gold for subsequent cyanidation or gravity recovery processes.

Operasionele werkvloei:
1. Voer & Inperking: Runofmyn of primêre gekneusde erts word in 'n verseëlde mortelboks gevoer.
2. Meganiese perkussie: A camshaft lifts multiple cast iron or steel stamps (skoene) in sequence, which drop onto the ore bed under gravity.
3. Ore Reduction: The repeated impact fractures the quartz matrix, gradually reducing the ore to a fine sand or slime consistency.
4. Was & Ontslag: A continuous flow of water washes the finely ground pulp through a discharge screen, allowing sized material to exit for further processing.

Toepassingsomvang & Beperkings:
Ideaal vir: Hard rock gold vein processing, loodsaanlegte, klein tot medium skaal bedrywighede (150 TPD), and sites prioritizing robust, simpler technology over complex ball mill circuits.
Beperkings: Nie geskik vir sagte nie, kleiryke ertse wat verpakking veroorsaak; requires consistent feed size; generally has a lower throughput ceiling compared to large rotary ball mills.
