When setting up a primary crushing operation for diamond-bearing ore in Cameroon with a target throughput of 300 tons per hour (TPH), selecting the right jaw crusher is critical to ensuring efficiency, reliability, and long-term profitability. The geology of diamond deposits in regions such as the Bakouma area in the Central African Republic—near Cameroon’s eastern border—often involves hard, abrasive kimberlite or alluvial ore with varying degrees of hardness. This makes robust and efficient primary crushing equipment essential.

For a 300TPH diamond processing plant, the ideal jaw crusher must balance high capacity, durability, and ease of maintenance. Among available options, the PE-900×1200 or the larger PE-1000×1200 models are commonly recommended for such applications. These are heavy-duty, single-toggle jaw crushers designed for primary crushing of hard and tough materials.

The PE-900×1200 can typically handle feed sizes up to 750 mm and deliver an output range of 200–350 TPH, depending on feed gradation and material density. This makes it well-suited for a 300TPH operation when fed consistently and supported by proper upstream screening or scalping. For more demanding conditions or larger feed sizes, the PE-1000×1200 offers increased throughput and a larger feed opening (1000×1200 mm), capable of processing up to 400 TPH under optimal conditions.

Crucially, in diamond mining, minimizing the risk of diamond breakage during primary crushing is a priority. While jaw crushers do generate significant compressive force, proper setting and controlled feed size can reduce excessive fracturing of liberated diamonds. Installing a grizzly feeder or vibrating screen before the crusher helps remove finer material and ensures a more uniform feed, reducing stress on the crusher and improving liberation efficiency.

Maintenance is another key consideration in remote locations like eastern Cameroon, where access to spare parts and technical support may be limited. Jaw crushers with simple designs, easily replaceable jaw plates, and widely available components are preferred. Regular inspection of toggle plates, bearings, and adjusting systems ensures sustained performance.

Power requirements for a 300TPH jaw crusher typically range from 110 to 160 kW. A reliable power supply—either grid-connected or via diesel generators—must be in place. Integration with conveyor systems and dust suppression measures also enhances operational safety and environmental compliance.

Several manufacturers offer suitable models, including reputable Chinese producers like Shibang Group, Zhongxin Machinery, and SBM, which provide cost-effective solutions with proven performance in African mining conditions. European brands such as Metso and Sandvik also offer high-end models, though at a higher capital cost.

In conclusion, for a 300TPH diamond primary crushing plant in Cameroon, a PE-900×1200 or PE-1000×1200 jaw crusher represents a practical and efficient choice. When paired with proper feeding equipment, maintenance planning, and operational oversight, it can deliver consistent performance in the challenging conditions typical of diamond mining operations in Central Africa.
