Introduction to twin-stage crusher

The twin-stage crusher or the two-stage crushing machine is improved upon the traditional small sized hammer crusher, so it is also called the dual rotor hammer fine crusher. The twin-stage crusher owns two sets of rotors which can crush the materials twice from top to bottom. The single one crusher can realize the crushing effect of two common crushers.

Two-Stage Crusher

Application of twin-stage crusher

The twin-stage crusher is able to break materials including limestone, bricks and tiles, coal cinder, furnace cinder, slag, gangue and construction waste etc. The twin-stage crusher owns no installation of grid plate and screening net, which prevents the blocking problem happening to the high temperature and high moisture materials during the crushing process. The twin-stage crusher equals two hammer crushers working together. The reasonable combination realizes the series application of two sets of rotors.

Working principle of twin-stage crusher

When it works, the twin-stage crusher's two rotors revolve at the same time at high speed driven by the double electric motors. Materials inside the crushing cavity are crushed again immediately by the high-speed revolving low level rotor's hammerhead after first being crushed by the high level rotor. Materials hit each other at full speed and are crushed completely, forming coal cinder powder with the discharging size smaller than 3mm.
