KAHL - Model EAPR - Automatic Pelleting Press Control System
Automation is in the focus of KAHL systems. We have developed the EAPR and DISTAMAT for the automatic control of our KAHL flat die pelleting presses. The EAPR from KAHL consists of a local control cabinet with graphic touch panel (TP) and a PLC with Step 7 CPU as central components. It thus controls and regulates all relevant process parameters. As an option, the DISTAMAT can be used for continuous adjustment and regulation of the roller gap, as good pellet quality requires a constant roller gap. Our EAPR and DISTAMAT systems therefore ensure optimum press operation combined with low manpower requirements.
Applications and Advantages:
- One control system for all press types and sizes
- Good visualization through the use of pictograms
- Fully automatic operation according to the preselected process parameters
- Minimized downtimes
- Storage and display of process data or error and alarm messages
- Control and monitoring of the pelleting press, proportioning screw, mixer, auxiliary units as well as the cooler and the upstream and downstream conveying elements as required
- Control of the pelleting press (load dependent), the throughput in t/h, the steam and the liquid. Optionally, up to four liquids can be added additionally to the mixer
- Simple operation and control using the touch panel
- Error and alarm messages
- System diagnostics
- Remote maintenance of the PLC controller and assistance in case of problems by the KAHL Service Team
- Video monitoring of machines

- DISTAMAT
DISTAMAT: The automatic distance control ensuring constant roller gap provides an optimum pellet quality and increases the service lives of pan grinder rollers and die
A high pellet quality requires a constant roller gap (distance between die and pan grinder roller). This is ensured by the DISTAMAT – the automatic distance control.
- Continuous adjustment and control of the roller gap
- Higher, more constant pellet quality
- Minimized wear of the die
- Simple retrofitting of existing pelleting press control system
Automatic unblocking of the pelleting press (option)
The DISTAMAT ensures a continuous preselection of the roller gap. Depending on the deviation from the setpoint value, the pressure of the hydraulic system of the pelleting press is controlled in such a way that the roller gap is kept constant. Apart from the higher and more constant pellet quality which is achieved, the direct contact of die and pan grinder rollers which usually results from a product shortage is avoided.
Thus service lives of pan grinder roller and die are considerably increased.
By means of alternating lifting and lowering of the pan grinder rollers, the optional unblocking program causes an automatic unblocking in case of an overfilling of the pelleting press.
As an optional extra of the EAPR, the Distamat is integrated into the EAPR control cabinet. If it is installed subsequently, a separate control cabinet with a PLC with Step 7 CPU and operator panel (OP) will be delivered. Furthermore the Distamat includes a special hydraulic unit with the required measuring sensors.
