Indentation Test Machine
Belt installed inside cylinder. Idler roll contacts belt at bottom. Weights simulate tonnage C=20,000 t/h. Cylinder supported by Powered Rolls. Roll Speed varies belt to 10m/s.
Installed in cold room
Temp range from -40°C to 30°C. Many belt samples, many idler roll samples.
