Granite is hard and highly abrasive. Traditional sand-making equipment often suffers from frequent hammer and impact plate wear, leading to high replacement costs and production downtime. HSM roller sand maker is specifically designed to tackle hard rock crushing.
Core Technology: Double-Roll Lamination + Full Hydraulic Intelligent Control

HSM roller sand maker uses the “double-roll lamination crushing + full hydraulic intelligent control” core technology. Two highly wear-resistant alloy rolls continuously compress and grind the material. Unlike impact crushers, the roller sand maker works at low speed and high pressure, offering low over-crushing, excellent product shape, and low energy consumption.
To address the hardness and abrasiveness of granite, HSM roller sand maker has achieved several technological breakthroughs:
Extra Wear-Resistant Roll Shells – Extended Service Life.
The roll surfaces use self-developed high-chromium manganese steel composite hardfacing technology or tungsten carbide inserts, achieving surface hardness up to HRC60 and wear resistance 2 to 3 times higher than ordinary materials. Even under continuous crushing of hard rocks like granite, the roll shells maintain stable service life, significantly reducing replacement frequency and downtime. Main shafts, bearing housings, and frames are all designed for heavy-duty conditions, ensuring high rigidity and stable operation.
High-Quality Finished Sand – Meets National Standards. The double-roll lamination process significantly improves particle shape – the output is cubic, well-graded, with low flakiness content, fully meeting national standards for construction sand. The lamination process also effectively reduces fine powder generation, producing sand with good shape and uniform gradation.
Intelligent Control – Flexible Switching Between Coarse and Fine Sand. The equipment is equipped with an intelligent control system that allows precise roll gap adjustment. Coarse and fine sand specifications can be easily switched to meet different project requirements. The full hydraulic system supports automatic release protection and stepless roll gap adjustment, handling tramp iron or feed fluctuations without equipment damage.

Low Energy Consumption, Low Maintenance – Controllable Operating Costs. The optimized power transmission system reduces energy consumption, achieving “more sand, less power.” Combined with sealed dust-proof design and low-noise operation, the equipment easily meets environmental requirements. The hydraulic protection system automatically releases when encountering hard objects, ensuring low failure rates in continuous operation.
Complete Model Range – Suitable for Sand Plants of All Scales
HSM roller sand makers come in a complete range of models to meet different production requirements:
Small spring-type models (e.g., 2PGT400×250) with 2-20 t/h capacity – ideal for start-up sand plants or small projects.
Medium hydraulic models (e.g., 2PGY1200×800) with 50-150 t/h capacity – suitable for regular production needs.
Large CNC models (e.g., 2PGY2000×1200) with 200-400 t/h capacity – designed for large-scale production lines.
No matter the scale of your sand plant, there is a matched hard rock sand-making solution. Thousands of sand plants nationwide have proven that HSM roller sand makers deliver higher output and lower cost per ton when processing granite.
