Product description

What is Smooth Roll Crusher

The Smooth Roll Crusher represents another breakthrough in the manufacturing of sand and aggregate production equipment. Also known as a dual-roll crusher or dual-roll sand maker, it utilizes two motors to drive dual rollers that crush and grind materials. It is suitable for fine crushing operations where the feed size is below 80mm and the final product size ranges from 50 mesh to 20mm.

The Smooth Roll Crusher is a kind of machine which is extended by the spring roller crusher. The advantage of hydraulic structure is that it can control the pressure between two reliefs accurately. Long-term continuous operation can still guarantee the crushing pressure between two rollers. Therefore, the equipment of roller crusher in the grinding system can give full play to the production capacity of the grinding equipment. Generally, the output can be increased by 30%~40%, and the total energy consumption can be reduced by 20%-30%.

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.    

The double roll crusher uses two independently driven rollers that rotate in opposite directions, generating extrusion and shearing forces to crush materials. Feed material enters through the inlet, is crushed by the rollers, and discharged naturally. If unbreakable or oversized materials are encountered, the hydraulic cylinders or springs automatically retract the rollers to widen the gap, allowing the material to fall through safely. The discharge size is adjusted by controlling the hydraulic or spring pressure.
