Double Roller Sand Making Machine

Professional Crushing & Shaping Solution for Premium Artificial Sand

Product Overview

The Double Roller Sand Maker is a high-efficiency fine crushing and shaping equipment designed for artificial sand production. By utilizing counter-rotating dual rollers, it generates powerful extrusion and shearing forces to process river pebbles, limestone, granite, and mineral tailings into high-grade cubic sand.

Engineered for maximum stability, this machine ensures the finished aggregate meets the strictest technical standards for high-grade concrete and large-scale infrastructure projects.

Main Applications

• Sand Plants: River pebble & granite crushing.

• Mining: Mineral tailings reprocessing.

• Waste Recycling: Construction debris projects.

• Infrastructure: Highway & railway aggregate.

Key Advantages

Superior Shape

Produces cubic-shaped sand with low needle content (≤5%), ideal for high-strength concrete aggregates.

Energy Efficiency

Reduces energy consumption by 50%–60% compared to traditional impact sand makers.

Low Operational Cost

Simple structure with durable alloy roller shells, ensuring long replacement cycles and minimal downtime.

Working Principle

The two roller shafts rotate in opposite directions. Materials are evenly fed into the gap and crushed by combined extrusion and shearing forces. An integrated hydraulic safety system automatically protects the rollers from uncrushable impurities, ensuring continuous and safe operation.
