A combination of dehumidifier heat pump and sludge belt conveyor, with compact design and small footprint. Able to run continuously with sludge feeding and discharging systems. Equipped with PLC control and friendly HMI, the machine can be almost left unattended and thus a lot of manpower are saved. Enclosed operation prevents odor escaping. Daily drying capacity ranges from 900kg to 81 tons of standard wet sludge.
Layout of drying zone:
Belt type
Auxiliary equipment:
wet sludge Feeder, wet sludge hopper,
sludge anti-clog device, sludge slitting machine,
dry sludge discharger, dry sludge hopper,
cooling tower, cooling control cabinet
Optional auxiliary equipment:
screw sludge dewatering machine.
Operation Mode:
Continuous drying (capacity: water 600-54000kg/day)
Applicable dewatering method:
decanter, press filter, belt filter, screw press etc
Sludge Data:
moisture content before dewater: 95% ~99.8%
moisture content before drying: 83%-70%
moisture content after drying : 40% -10% adjustable
Energy efficiency: 3-5kg H2O/kWh
Sludge takes about 1~3 hours to be dried. Suitable for organic sludge.
There are 4 models of belt type sludge dryer, i.e., 5-ton, 9-ton, 19-ton, 35-ton units. 3 submodels are derived from model 19-ton, 6 submodels are derived from 35-ton units each. So in total there are 4 models and 11 submodels of belt type sludge dryers.
