The pouring head recycle to the head with mixing chamber sized for continuous pouring.
Pneumatic system to actuate the recycle/pouring phase independent for the 3 components.
The pouring head has nozzles at variable diameter and special valves on recycle for adjusting the recycle and pouring pressures.
Special sealing on the mixer shaft, automatically lubricated during the pouring phase.
Mixer at high shear driven by three-phase electric motor.
Mixing speed from 2000 up to 6000 rev/min obtained by three-phase electric motor inverter controlled for speed variation..
Mixing chamber cooled by means of water circulation.
All mixing head parts in contact with the acid will be made using a special “Hastelloy-C” material.

MACHINE/HEAD CONNECTIONS

The connections between machine/mixing head are made in a rational way with rigid and flexible hoses suitable for pure resin, blowing agent and acid.

This cleaning circuit is composed of: 18 litres capacity pressurised stainless steel cleaning fluid tank;
tank pressurisation system, including pressure regulator and manometer; pressure relieve valve, calibrated to 4 Bar;
intercepting solenoid valve for cleaning fluid and drying air;
possibility to set, through the operator panel, timers to adjust either fluid and drying air quantity;
special manual valve to clean the mixing head in case of mains power failure;
minimum level control and related alarm within the tank;
manual and automatic washing cycle of the mixing head body, controlled by the PLC.
