Rwanda 250t/h Crushing and Sand-Making Production Line

This 250-tonne-per-hour pebble sand-making project serves as a vital raw material supply base for local infrastructure development. Addressing the physical characteristics of pebbles—hard texture, high silica content, and resistance to crushing—the project employs a bespoke, modern deep-processing system featuring high compressive strength and low wear. Raw materials are first uniformly and continuously fed by a vibrating feeder into a jaw crusher for primary coarse crushing, where large rock blocks are instantly reduced to medium-sized particles. The material then proceeds to a single-cylinder hydraulic cone crusher, which achieves efficient medium crushing through its substantial crushing force and throughput capacity. It is subsequently conveyed to a multi-cylinder hydraulic cone crusher, where advanced laminar crushing principles are employed for fine crushing. This process significantly optimises aggregate particle shape while maintaining production output. To meet high-grade concrete sand standards, the system incorporates a high-performance impact sand-making machine at the end for shaping and sand production. The final output undergoes multi-stage precision grading via a circular vibrating screen. The entire production line features a smooth process flow and well-balanced gradation.
