Working Principle

At its heart, the machine utilizes a high-speed rotor that throws fed raw material (typically <50mm) against a crushing chamber (anvil ring or rock shelf). Impact crushing occurs through either:

• 1. “Rock-on-Rock” Principle: Material impacts against a cascade of other falling material particles, resulting in excellent particle shape and minimal wear on metal parts. Ideal for less abrasive rocks.

• 2. “Rock-on-Iron” Principle: Material impacts against metal anvils or liners within the crushing chamber, offering higher reduction ratios and suitability for highly abrasive materials. Wear parts are replaceable.

The intense impacts fracture the rock along natural cleavage lines, producing optimally shaped, cubical sand grains. The final product size is precisely controlled by adjusting rotor speed, feed rate, and the configuration of the crushing chamber/exit ports.

Key Features & Advantages

• 1. Superior Sand Quality: Produces cubical, well-graded sand particles with optimal surface texture. This significantly enhances the workability, strength, and durability of concrete and asphalt mixes compared to irregular natural sand.

• 2. High Production Efficiency: Capable of generating large volumes of sand (typically ranging from 50 TPH to 500+ TPH) consistently and reliably, meeting demanding project requirements.

• 3. Particle Shape Control: Precise adjustments allow fine-tuning of the particle shape and gradation curve, enabling production of sand tailored for specific applications (e.g., plastering sand, concrete sand).

• 4. Low Operational Costs:

  • Reduced Wear: Advanced wear-resistant materials (like tungsten carbide tips, high-chrome liners) and optimized crushing principles (especially rock-on-rock) significantly extend component life.
  • Energy Efficient: Modern designs optimize power consumption per ton of sand produced.

• 5. Versatility: Can process a wide range of feed materials: granite, basalt, limestone, river pebbles, quartz, diabase, iron ore, copper ore, slag, concrete waste, etc.

• 6. Environmental Sustainability:

  • Conserves Natural Resources: Eliminates dependency on ecologically sensitive river sand mining.
  • Waste Utilization: Can process construction demolition waste and industrial slag into valuable sand.
  • Waterless Process: Unlike traditional washing, most modern sand makers produce dry, ready-to-use sand, conserving water and eliminating slurry ponds.

• 7. Low Fines Generation: Optimized crushing minimizes the production of excessive micro-fines (<75 micron), which can be detrimental to concrete quality.

• 8. Compact Design & Easy Maintenance: Modular designs facilitate installation and relocation. Critical wear parts are often designed for easy access and replacement, minimizing downtime.

• 9. Closed-Circuit Operation: Easily integrated with screening equipment to recirculate oversize material and achieve precise final product sizing.
