In the mixing room, a 40 cu ft (1.13 m3) Munson Rotary Batch Mixer distributes resins, waxes and fillers uniformly in 1,000 lb (454 kg) batches. Ingredients are fed to the mixer via belt conveyor, hopper and flexible screw conveyor. At right are HMT's hot-melt adhesives cast as films.
Ingredients are emptied into a hopper from which a flexible screw conveyor transfers them to the intake of the Rotary Batch Mixer.
Clean-out doors allow unrestricted access to the mixer interior. The horizontal vessel rotates on external trunnion rings located at each end, with no internal shaft or bearings contacting material being mixed.
The mixer discharges uniformly blended product into a mobile bin, which is wheeled to low-pressure extruders and the hot-melt casting process. Dust is collected during discharge.
HMT Manufacturing's hot-melt adhesives are cast as films for laminating virtually any material to almost any substrate.
