1. PEMBUKAAN PAINPOINT DRIVEN

Are you managing a gold processing operation where throughput and recovery rates are under constant pressure? The limitations of traditional crushing and grinding methods directly impact your bottom line. Pertimbangkan cabaran operasi biasa ini:

Throughput Rendah & Masa Henti yang Tinggi: Pemakanan manual, inconsistent ore sizing, and frequent maintenance stops on primary crushers create bottlenecks, limiting tonsperhour capacity and increasing labor costs.
Pembebasan Emas yang tidak cekap: 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.
Kos Operasi yang Tinggi: Reliance on multiple pieces of equipment for primary crushing, secondary breaking, and feeding results in elevated power consumption, spare parts inventories, and operator overhead.
Had Kebolehskalaan: tetap, 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. GAMBARAN KESELURUHAN PRODUK: 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. Ia direka bentuk untuk menerima runofmine (ROM) ore and reduce it to a consistent, manageable size suitable for secondary processing in ball mills or hammer mills.

Aliran Kerja Operasi:
1. Memuatkan: ROM ore is fed into the integrated feed hopper, designed to manage large, irregular rocks with minimal bridging.
2. Menghancurkan: Mechanically driven heavy stamps (camshaft or leveroperated) are lifted and dropped onto the ore bed contained within a durable mortar box.
3. Saiz & Pelepasan: 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. Integrasi Sistem: The unit functions as the primary node in a circuit, with discharge ideally conveyed to a sorting area or directly into secondary grinding.

Skop Permohonan & Batasan:
Sesuai Untuk: 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.
Batasan: Tidak direka bentuk sebagai penyelesaian pengisaran halus. Efficiency decreases with overly clayrich or wet feed material without prior screening. Requires a stable foundation due to dynamic loads.
