Cast Iron Twin Shaft Grinder


Multipurpose Two Shaft Grinder

Product Description



Excellent Cutting Results,Crusher,Macerate, Dual-Shaft Grinder



The Crusher is a macerating unit with a powerful intake function, universal macerating unit for solids contained in liquid.The basic design of the dual-shaft grinder is based on the proven Accuvon Rotary Lobe Pump, Cutting blades are used instead of the ingenious rotors. With the wide spectrum of 4 series (flow rates of up to 500 m³/h), a large selection of equipment and additional parts, the Crusher is suitable for just about any application.

The Crusher reliably processes coarse material such as fibers, wood pieces, plastics, membranes, textiles and many more and ensures that downstream machines and pumps operate smoothly. The Crusher homogenizes the medium, thereby facilitating the pumping process.



operating principle


The dual-shaft grinder was designed using the principle of the Accuvon Rotary Lobe Pump. Instead of the rotating lobes, this device has interconnecting cutting blades set on the hexagonal carrier shaft and attached with a central bolt.

The different circumferential speeds and blade configurations ensure excellent cutting results.

blade configurations


The degree to which the Accuvon Crusher cuts is determined by the choice of blade configuration, the teeth profiles, the blade widths and the flow speed.

Currently, a choice of nine different blade configurations can be selected depending on the assignment. The different circumferential speeds of the shafts create a tearing/cutting result. The use of hardened steel ensures the blades are kept sharp for longer. Defective cutting blades can be individually replaced.



Control technology


The Crusher generally runs in reverse for 5 seconds upon starting – afterwards changing to the original direction of rotation

Reversing in the event of overload (blockages or clogging): Reversing upon reaching 70% of the motor power rating (value can be freely configured via the control unit)

Alert: when reversing five times within ten minutes due to overload Counter which runs in the background to record the number of load-dependent reversals

The Accuvon control technology guarantees trouble-free operation of the Crusher.
