The Roller sand making machine 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%.
River pebbles, calcite, quartz, glass, marble, cobblestone, bentonite, iron ore, bluestone, mountain rock, limestone, weathered sand, diabase, granite, basalt, and other materials for crushing and sand-making.
The Roller Sand Making Machine 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.
The crusher is classified into small, medium, and large models:
