1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de traitement de l'or où les taux de production et de récupération sont sous pression constante ?? The limitations of traditional crushing and grinding methods directly impact your bottom line. Tenez compte de ces défis opérationnels courants:

Faible débit & Temps d'arrêt élevés: Alimentation manuelle, inconsistent ore sizing, and frequent maintenance stops on primary crushers create bottlenecks, limiting tonsperhour capacity and increasing labor costs.
Libération d’or inefficace: Inadequate initial particle size reduction forces your grinding circuit to work harder, consuming excessive energy and still risking poor liberation of gold from host rock.
Coûts opérationnels élevés: Reliance on multiple pieces of equipment for primary crushing, secondary breaking, and feeding results in elevated power consumption, spare parts inventories, and operator overhead.
Limites d'évolutivité: Fixé, nonmodular systems hinder your ability to efficiently adjust processing capacity in response to changing ore grades or mine plans.

Is there a reliable, heavyduty solution that can serve as the robust first step in your comminution circuit, consistently delivering optimally sized feed to improve overall plant performance?

2. APERÇU DU PRODUIT: HeavyDuty Stamp Mill for Primary Gold Ore Crushing

Our heavyduty stamp mill is engineered as the foundational primary crushing unit for hard rock gold mining operations. Il est conçu pour accepter le runofmine (ROM) ore and reduce it to a consistent, manageable size suitable for secondary processing in ball mills or hammer mills.

Flux de travail opérationnel:
1. Chargement: ROM ore is fed into the integrated feed hopper, designed to manage large, irregular rocks with minimal bridging.
2. Écrasement: Mechanically driven heavy stamps (camshaft or leveroperated) are lifted and dropped onto the ore bed contained within a durable mortar box.
3. Dimensionnement & Décharge: Crushed material passes through a grated screen at the base of the mortar box. Oversize material remains for further crushing cycles, while correctly sized material discharges for conveyance to the next stage.
4. Intégration du système: The unit functions as the primary node in a circuit, with discharge ideally conveyed to a sorting area or directly into secondary grinding.

Champ d'application & Limites:
Idéal pour: Processing quartz veins, hard rock lode deposits, and sulfide ores where gold is locked within the matrix. Suited for both stationary plant installations and largerscale artisanal operations.
Limites: Not designed as a finegrinding solution. Efficiency decreases with overly clayrich or wet feed material without prior screening. Requires a stable foundation due to dynamic loads.
