Sludge Dryer Introduction

Sludge rotary dryer is a drying equipment specially developed and designed for sludge, which has the characteristics of high moisture, high viscosity, high water holding capacity and low calorific value. A special design is made on the internal structure of the sludge dryer, which not only improves the thermal efficiency, but also effectively avoids the sticking and excessive drying of sludge in the dryer.

Advantages of Slurry Dryer

Strong overload resistance, large processing capacity, low fuel consumption and low drying cost.
Adopt computer automatic control, which can realize remote control and easy operation.
The specially designed retaining wheel structure greatly reduces the horizontal thrust caused by the tilting of the drying equipment.
Multiple heating sources available for selection.

Complete Sludge Rotary Drying System

The whole sludge rotary drying system consists of the dehydrator machine, feeder, sludge rotary dryer, discharging machine, induced draft fan, cyclone dust collector and distribution cabinet, etc.

Wide Application

The sludge dryer is suitable for drying activated sludge, sewage sludge, petrochemical sludge, papermaking sludge, printing and dyeing sludge, tanning sludge, electroplating sludge, municipal sludge, biological fermentation sludge, etc. Besides, it is also applied to coal sludge drying and coal slurry drying.

Working Principle

Firstly, high moisture sludge is dewatered by the dewatering machine, then transported to the rotary drum dryer by the belt conveyor, where it fully contacts with the hot air. With the running of the rotary dryer, sludge with hot air moves to the end of dryer body. After drying, most of the dry materials will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, and then discharged through the conveyor.
