Frequently Asked Questions

A double rotor sand making machine uses two counter-rotating rotors that create a combined crushing and shaping action. This design significantly improves throughput, reduces over-crushing, and produces a more uniform, well-shaped sand particle compared to single rotor configurations. Energy efficiency per ton is also higher.

Yes. It is typically deployed as the tertiary or final crushing stage, receiving pre-crushed material (feed size ≤40mm) from upstream jaw and cone crushers, and producing final manufactured sand ready for washing and screening.

Depending on the model, output capacity ranges from 100 t/h to over 500 t/h. Because both rotors work simultaneously, the effective capacity is substantially higher than a single rotor machine of similar dimensions.

Inspect rotor blades and impact blocks every 100–200 hours for wear. Replace worn blades symmetrically to maintain rotor balance and avoid excessive vibration. Bearings should be re-greased every 300 hours and replaced annually or as required based on condition monitoring.
