High-Hardness Material Expert: Solving Crushing Pain Points Efficiently
Tired of struggling with hard aggregate (granite, river pebbles) and marble crushing? Ordinary crushers wear out fast, break down often, and fail to deliver consistent results—this Roller Crusher, as a professional aggregrate and marble sand making machine, solves it all with targeted design.
Crushing Principle of Roller Crusher
1. Hardness-Adapted Design: No Fear of Tough Materials
Marble has a Mohs hardness of 3-5; aggregate (like granite) hits 200+MPa in compressive strength. The Roller Crusher uses HRC60+ high-chromium alloy rollers and flexible extrusion to avoid impact wear. It handles 4-5 inch raw materials directly—no pre-crushing needed—making it a pro at tackling hard materials.
Ordinary crushers need frequent part swaps. But the Roller Crusher’s wear-resistant rollers extend marble-crushing part life by 40%. For aggregate, maintenance is only needed once a year. This slashes downtime and replacement costs, keeping production steady.
3. High-Quality Finished Products: Ready for Use
Double-roll extrusion makes aggregate and marble sand with cubic grains, even gradation, and ≤3% powder. Marble sand keeps 95% whiteness. No re-screening is needed—use it right away for concrete or decor. Adjust output (0-5mm) easily to fit any job.
4. Energy-Saving & Eco-Friendly: Cost-Effective and Compliant
The Roller Crusher uses just 5kWh per ton—30% less than traditional models. It fits 3-5㎡, and one person can run it, cutting labor costs. Its closed chamber and dust filter keep dust under 10mg/m³ and noise under 75dB, so it meets all environmental rules.
