High Efficiency Portable Stone Crusher 5TPH Small Portable Rock Crusher

Portable stone crusher for small scale gold mining in Africa

1.Product Introduction Portable Stone Crusher

The Portable Stone Crusher is a rugged, highly mobile crushing solution specifically engineered to meet the unique challenges of artisanal and small-scale gold mining (ASGM) in Africa. Designed for durability and ease of use in remote locations, this equipment bridges the gap between manual labor and industrial processing. It efficiently reduces hard quartz gold ore into fine gravel or sand, ready for milling and gravity concentration. With a focus on fuel efficiency, simple mechanical maintenance, and extreme portability, it allows miners to process ore directly at the pit head, maximizing gold recovery while minimizing manual transport and labor costs.

2.Application Portable Stone Crusher

• Artisanal Gold Mining: Primary crushing of gold-bearing quartz veins and hard-rock ore in remote bush locations.

• Hard Rock Prospecting: On-site sample crushing for geologists and prospectors to evaluate ore grades quickly.

• Small-Scale Beneficiation: Providing consistent feed material for ball mills, hammer mills, or centrifugal concentrators.

• Remote Infrastructure: Occasional use for producing construction aggregate for small-scale mine site infrastructure or roads.

3.Working Principle Portable Stone Crusher

• Manual or Mechanical Loading: Raw ore is fed into the hopper, where it is directed into the crushing chamber.

• Compression Crushing: A high-strength Jaw Crusher mechanism uses a "chewing" action; a moving jaw plate compresses the rock against a fixed plate, shattering the hard quartz ore.

• Adjustable Discharge: The gap at the bottom of the jaws (discharge setting) can be manually adjusted to control the size of the output material, ensuring it is small enough for the next stage of processing.

• Independent Power: Most units are powered by a heavy-duty diesel engine (or optional electric motor), utilizing a simple belt-drive system to ensure high torque and easy repair without specialized tools.

4.Advantages Portable Stone Crusher

• High Portability: Mounted on a robust wheeled trailer or compact skid, the unit can be towed by a 4x4 or moved manually over rough terrain.

• Diesel Engine Reliability: Designed to operate in high temperatures and dusty environments using standard diesel fuel, common in remote African mining regions.

• Minimal Maintenance: Features a simplified mechanical design with grease-lubricated bearings and reversible jaw plates to extend the life of wear parts.

• Low Operating Cost: Drastically reduces the time and physical effort required compared to manual "dolly-pot" crushing or handheld hammers.

• Hard Rock Capability: Specifically built with high-manganese steel components to crush hard quartz, which is common in African gold deposits.
