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.

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.

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.

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.
