Slab cooling unit Purpose: This is the downstream auxiliary to the mixer or the dispersion mixer. It works with the double conical-screw extruder sheeter and is designed to perform continuous operations of rubber slab conveying, separant applying, air cooling, drying, cutting and wig-wag stacking. Features 1. The operations of separant applying, air cooling, drying, cutting and wig-wag stacking are performed in a single machine, forming continuous production at high efficiency. 2. Rubber slabs are soaked thus applied with the separant so that the coating is even without pollution to the environment. 3. A long time is set for air cooling of rubber slabs so that the cooling effect is good. 4. Slabs can be cut to length during operation and the length is adjustable. 5. Use of the PLC control and the frequency-control speed regulation makes it possible to control the whole process.
