Hydraulic height control unit DISTAMAT

Overview
Depending on setpoint deviations, the hydraulic pressure of the pellet mill system is regulated so the roller gap is maintained at the required value. This enables continuous preselection of the roller gap and prevents direct contact between die and pan grinder rollers that can occur during material shortage, thereby extending service life of die and pan grinder rollers. An optional unblocking program provides automatic unblocking in case of overfilling by alternating lifting and lowering of the pan grinder rollers.

Applications and Advantages

• Continuous adjustment and control of the roller gap
• More consistent pellet quality
• Reduced die wear
• Simple retrofitting to existing pellet mills
• Optional automatic unblocking of the pellet mill
• Error and alarm messaging
• Remote maintenance of the PLC and remote assistance by the manufacturer's service team

Integration and retrofitting
As an option of the EAPR control system, the DISTAMAT can be integrated into the EAPR control cabinet. For retrofitting, a separate control cabinet with a PLC (Step 7 CPU) and operator panel is supplied. The DISTAMAT includes a dedicated hydraulic unit with the required measuring sensors.
