Two-Stage Crusher
The Two-Stage Crusher, also known as a Double Rotor Hammer Crusher, is an advanced crushing machine designed to combine primary and secondary crushing into a single pass. It integrates two rotors operating in series, allowing material to be crushed twice consecutively without the need for intermediate handling. Its most distinctive feature is the absence of a grate bar (screen mesh) at the discharge opening, which makes it exceptionally effective for processing wet, sticky, or high-moisture materials without clogging.
Working Principle
The machine operates on a continuous two-step impact process:
First Stage Crushing: Raw material enters the upper crushing chamber where it is struck by the hammers of the first rotor.
Second Stage Crushing: The coarsely crushed material immediately falls into the lower chamber. Here, the second rotor (operating at a higher speed) delivers a secondary, high-intensity impact.
Discharge: Due to the lack of a screen, particles are discharged freely based on their size, typically achieving a fine output below 3mm.
Key Advantages
Anti-Clogging Design: The grate-free design ensures smooth operation even when processing materials with moisture content exceeding 15%.
High Efficiency: Two rotors working in tandem provide high reduction ratios and uniform particle size in a single pass.
Cost-Effective: Features a shift-gap adjustment technology; worn hammerheads can be repositioned rather than replaced immediately, significantly extending service life and reducing spare parts costs.
Versatile Application: Suitable for brittle materials such as coal gangue, shale, slag, construction waste (bricks/concrete), and limestone.
