Re-circulation network of all components for calibration before foaming
All chemical outputs are variable by ac speed drives
Closed foaming tunnel with two gas exhaust fans and having adjustable sidewalls and variable speed conveyor, which is made of metal slats and is 60 feet long (including fall plate section)
Process
All the p.u. chemicals are first mixed together in a mixing chamber and then taken into a metal trough where the initial reaction takes place
The rising foam then passes from the top of the trough on to a variable width fall plate, which then leads the expanding foam block along a metal slat conveyor for further expansion
Outputs
The machine delivers a maximum of 200 kg per minute
Metering System
Seven metering systems in total
Foaming Tunnel and Conveyor
The tunnel construction forms a complete enclosure around the foam slab with top plates, side walls and conveyor slats
The conveyor motor is also equipped with ac speed drive
Side walls can be adjusted from 1.1–2 m
The length of the conveyor is 13 meters
Trough and Fall Plate
The trough and fall plate section can be adjusted height wise at various levels to ensure more flattop blocks
Equipped with required motors and gearboxes
Paper Feed and Rewind
This is a 3-paper system
The bottom paper feed reel is mounted in front of the foaming platform and is equipped with unwinding motor for automatic operation
Rewinding of the side papers is at the other end of the tunnel and the rewinding speed is self-adjustable to synchronize with the conveyor speed
Control Panels
Attached at a convenient position on the foaming platform
Equipped with necessary electronics, flow meters, pressure gauges and ac variable speed drives
Storage Tanks
Polyol: 4000 liters
Tdi: 4000 liters
Methylene chloride: 1000 liters
The tanks of stannous octate, water, amine, silicone and colors are 100 liters capacity each
All tanks are equipped with level gauges, thermometers, safety valves, and manholes, drain valves/strainers, conditioning jacket and stirrers
Block Cut-Off Machine
Block cut-off machine is of traverse type, which can be adjusted to give various pre-determined lengths of blocks
