Sludge Dryer

Product Introduction

A lot of sludge is left over after the waste water treatment. The moisture content may be not high, but it's so mushy that it's hard to dry. Thermal drying is an intermediate sludge treatment process that consists of evaporating the water in the sludge. It significantly reduces the volume and weight of the sludge so that it is easier to recover.

Sludge Dryer Features:

High thermal efficiency : The thermal efficiency is 80% to 90%. The new internal structure strengthens heat conduction of dispersed materials, and eliminates the sticking phenomenon of the inner wall of the cylinder.
Stable drying quality : Since the heating mode is easy to control, the temperature inside the cylinder and the heat transfer rate of the partition wall can be kept relatively stable.
Long parts life, not easy to wear : The cylinder of the dryer is made of steel material, which has the characteristics of high hardness and high toughness.
Simple operation, environmental protection and energy saving : The dryer system has good sealing performance, and is equipped with a complete dust removal device, with little dust spillage and a good operating environment.
