Title of Invention

METHOD FOR DRYING PASTY MATERIALS AND APPARATUS THEREOF.

Abstract ON DRYING PASTY MATERIALS, PARTICULARLY SEWAGE SLUDGE, THE MATERIAL IS COMPACTED IN AN INTERMEDIATE DRYING STAGE WITH A DRY FRACTION OF 60 TO 80%, SO THAT RELATIVELY LOW ENERGY COSTS ARE REQUIRED. THE CONVEYING OF THE MATERIAL TAKES PLACE BOTH DURING PRE-DRYING AND AFTER LEAVING THE COMPACTOR ON ONE OR TWO AIR-PERMEABLE CONVEYOR BELTS (3,4) SUCCEEDING ONE ANOTHER IN THE CONVEYING DIRECTION AND WHICH ARE ENCLOSED IN A COMMON HOUSING (2). THUS, DRYING BEFORE AND AFTER CAMPACTING IS PERFORMED UNDER INDENTICAL METHOD CONDITIONS, SO THAT IT IS POSSIBLE TO PRODUCE A SIMPLE AND THEREFORE INEXPENSIVE INSTALLATION FOR PERFORMING THE METHOD. THE FINISHED PRODUCT HAS ADVANTAGEOUS CHARACTERISTICS WITH REGARDS TO DENSITY AND ABRASION RESISTANCE, SO THAT DUST PRODUCTION IS AVOIDED DURING SUBSEQUENT HANDLING.
