Low Temperature Sludge Dryer

  • Adjustable Final Sludge Moisture 10%~50%.
Know More


Low temperature sludge drying technology is injecting circulating, warm and dry air to evaporate and take away the moisture in the sludge cake produced by sludge dewatering equipment such as multi plate screw press, plate and frame filter press, super high pressure filter press and so on to achieve the purpose of sludge weight reduction. It is suitable for Municipal sludge and Industrial sludge such as pickling sludge, electroplating sludge, steelmaking ironmaking sludge, alumina sludge (red mud), oily sludge from oil fields and refineries, chemical and pharmaceutical sludge, papermaking sludge, printing and dyeing sludge and leather sludge, sludge weight reduction capacity of more than 70%, thereby greatly reducing enterprise production costs.

Overall Structure


 Adjustable Final Sludge Moisture 10% ~ 50% 

Characteristics & Features

1.Double Layer Mesh Belts
2mm mesh diameter (common length<1.8mm)
Double row sprockets, higher tensile strength
446 KN tensile strength, not easy to break

2. Double Corrosion Resistant Material
