How Does A Gold Rock Crusher Work?
2025-10-05Huashengming Gold Rock Crusher (primarily a roller crusher) operates on the principle of dual-roller compression crushing combined with shear tensile action. Hydraulic or mechanical adjustment precisely controls the discharge particle size (1-50mm), making it particularly suitable for crushing high-hardness or high-moisture sticky materials such as muddy gold ore and granite. 1. Core Crushing Principle Synergistic Action of Compression and Shearing Upon entering the gap between the two rollers, the material undergoes dual forces: high-pressure compression and serrated shearing: Compression Crushing: The two rollers rotate in opposite directions (with a designed speed differential), applying sustained high pressure to the material, causing the rock to fracture along its weak joints. Shear Tension: The serrated roller surfaces (e.g., wolf teeth, wave teeth) enhance shear forces on the material. This is particularly effective for sticky particles in muddy gold ore, where tension strips away the clay layers enveloping gold grains. This synergistic action significantly reduces over-crushing rates (<10%) and improves gold ore leaching efficiency. Simultaneous Particle Size Classification Certain models (e.g., high-efficiency classification crushers) incorporate direct screening through inter-tooth gaps during crushing. Qualified particles are rapidly discharged, while oversized particles are returned for re-crushing, preventing pulverization from repeated crushing. 2. Particle Size Control Mechanisms…
