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.
Components
1 Quick-release cover
2 Axial casing protection
3 Central clamping unit
4 Spacer rings
5 Cutting blades
6 Shaft seal
7 Block casing
8 Quench and control chamber
9 Carrier gear unit and gear reducer
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.
