With increasing requirements for solid waste resource utilization in mining, the crushing of tailings slag has become a key concern for processing plants and mines. However, tailings slag has complex composition, fluctuating moisture content, and contains hard metal particles. Traditional equipment often suffers from material sticking, wear, and uneven discharge, leading to production interruptions and difficulty meeting continuous operation demands. HSM Heavy Machinery introduces the tailings slag dedicated double tooth roll crusher, offering high reliability, low maintenance cost, and excellent product shape – providing an efficient solution for underground backfilling, road aggregate, and re‑processing of tailings slag.
Focus on Continuous Operation for Smooth Production

Tailings slag often contains a large amount of fine mud and high moisture content. Ordinary crushers easily experience material sticking to the crushing chamber and screen plate clogging, resulting in frequent shutdowns for cleaning. The HSM tailings slag crusher adopts a screen‑free gravity discharge structure – once the material is crushed to a size smaller than the roll gap, it falls directly without any retention zone. Combined with a self‑cleaning tooth profile design, material does not accumulate on the roll surfaces. Even when handling tailings slag with high moisture and high fine mud content, the equipment maintains continuous operation, greatly improving production line availability.
Simple Maintenance to Reduce Operating Burden
When conventional crushers process tailings slag containing hard particles, hammers or tooth plates wear out extremely quickly, requiring frequent replacement and resulting in high consumables costs. The HSM model uses high‑chromium alloy hardfacing tooth plates with excellent wear resistance, effectively resisting the cutting and impact of metal particles and quartz sand. The split tooth plate structure means that when local wear occurs, only the worn tooth plate needs to be replaced – not the entire roll. Maintenance is quick and convenient, significantly reducing downtime and spare parts consumption.
Good Product Shape to Meet Downstream Requirements

Impact crushers tend to generate excessive fines, which are not suitable for underground backfilling or road construction. The HSM double tooth roll crusher works on the low‑speed, high‑torque shearing principle, applying gentle tensile and shearing forces rather than high‑speed impact. The product is mostly irregularly shaped lumps with a good particle shape and very few fines. When used for underground backfilling, it reduces binder consumption and improves backfill strength. When used for road aggregate, the gradation is more reasonable with better compaction. The discharge size can be quickly adjusted via the hydraulic system, flexibly adapting to different process requirements.
Flexible Configuration for Various Scenarios
The crusher can be used as a single unit or combined with a vibrating screen to form a closed‑circuit crushing system, and can also be equipped with a magnetic separator to protect the equipment. Whether for coarse, medium, or fine crushing of tailings slag, it delivers stable performance. The equipment operates with low noise and low dust emission, and can easily meet environmental requirements when matched with a dust collection system.
