1. PYNPUNT GEDREWE OPENING

Bestuur jy goudherwinningsbedrywighede wat deur inkonsekwente deurset belas word, excessive downtime for maintenance, en onvoorspelbare bedryfskoste? Key challenges in primary ore crushing and liberation often include:

Hoë operasionele stilstand: Frequent liner changes and mechanical failures in crushing circuits halt your entire processing line, duisende per uur in verlore produksie kos.
Ondoeltreffende Goudbevryding: Inconsistent particle size from primary crushers leads to poor contact in subsequent leaching or gravity circuits, directly reducing overall recovery rates.
Oormatige energieverbruik: Older crushing technologies consume disproportionate power per ton of ore processed, winsmarges erodeer.
Hoë Onderhoudsarbeidskoste: Kompleks, laborintensive maintenance routines for legacy stamp mills or jaw crushers increase your total cost of ownership and safety exposure.
Skaalbaarheidsbeperkings: Inflexible equipment that cannot adapt to varying ore hardness or feed grades creates bottlenecks in expanding operations.

Is jou operasie op soek na 'n robuuste, highavailability solution for primary gold ore reduction that delivers consistent sizing, reduces lifecycle costs, and protects your recovery circuit’s efficiency?

2. PRODUK OORSIG

The modern heavyduty stamp mill is a mechanized percussion crushing system engineered for the primary liberation of gold from quartz and hard rock ore. It is designed as a reliable, highimpact workhorse for mediumtohigh volume operations where consistent sub10mm output is critical for optimal downstream cyanidation or gravity recovery.

Operasionele werkvloei:
1. Voer Inleiding: Runofmyne (ROM) ore is fed into a robust steel mortar box.
2. Meganiese perkussie: Powered camshafts lift and release a series of weighted stamps (5002000kg elk), beheerde lewering, highimpact blows onto the ore bed.
3. Progressiewe vermindering: Ore is crushed through repeated impact against hardened die plates within the mortar box.
4. Misafvoer: Finely crushed material exits through a discharge screen at the mortar box perimeter, mixed with water to form a slurry ready for secondary processing.

Toepassingsomvang & Beperkings:
Ideaal vir: Hard rock gouderts (kwarts are), loodsaanlegte, operations prioritizing mechanical simplicity and high uptime over ultrafine grinding.
Beperkings: Nie geskik vir sagte nie, kleiryke ertse wat verpakking veroorsaak; vereis konsekwente voergrootte (tipies <100mm); operates most efficiently within defined moisture content parameters.
