Kuota e prodhuesit të minierave të arit të mullirit të pullave
1. HAPJE NGA PIKA E DIKIMIT
A po menaxhoni operacionet e rikuperimit të arit të ngarkuara nga xhiroja jokonsistente, konsumi i lartë i reagentëve, and excessive downtime for liner changes? The limitations of conventional crushing and grinding circuits directly impact your bottom line. Merrni parasysh këto sfida:
Recovery Inefficiency: Coarse gold can be lost in traditional ball mill circuits, leading to a measurable decrease in overall yield.
Kostot e larta operacionale: Frequent maintenance cycles for complex grinding systems result in significant labor costs and production halts.
Scalability Issues: Modular or remote operations struggle with the footprint and infrastructure demands of standard milling setups.
Process Complexity: Integrating effective gravity recovery within a continuous flow sheet often requires additional, costly equipment.
What if a proven, robust technology could consolidate crushing and primary grinding while enhancing gravity recoverable gold (GRG) capture at the head of your circuit?
2. PËRMBLEDHJE E PRODUKTIT: Industrial Stamp Mill for Gold Ore Processing
An industrial stamp mill is a mechanical crusher designed for the coarse liberation of gold from hard rock ore. It utilizes heavy, verticallylifted stamps that are repeatedly dropped onto ore fed into a mortar box, fracturing material through direct impact. This method is particularly effective for freemilling ores where gold is unlocked at a coarse size.
Rrjedha e punës operative:
1. Prezantimi i ushqimit: Runofmine ose mineral i grimcuar primar (<50mm) is fed into the stamp mill’s mortar box.
2. Thërrmimi me ndikim: Pulla të ngritura mekanikisht (5001000+ kg secila) rënie në një sekuencë të kontrolluar, pluhurimi i mineralit kundër një forme të ngurtësuar.
3. Formimi i slurit & Shkarkimi: Water is introduced to create a slurry, which flows over an amalgamation plate (if used) and is discharged for further classification or secondary processing.
Fusha e Aplikimit & Kufizimet:
Ideale për: Përpunimi i lirë i xeheve të arit, impiantet pilot, operacione në shkallë të vogël (150 TPD), historical site reprocessing, and operations prioritizing robust, lowtech reliability with high GRG recovery.
Kufizimet: Not suitable for refractory ores requiring fine grinding for chemical liberation. Higher energy per ton compared to some modern circuits for fine grinding. Requires consistent feed size control.
