Rotary Drum dryer Overview
Rotary Drum Dryer Introduction

Rotary drum dryer is a kind of direct heating method. This direct heating method is of high efficiency and low lost.

A rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industrial and coal slime in coal mine, etc. Rotary dryers can be widely used to dry various materials,
most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulphate, filter cakes, sewage sludge, other sludge, etc.

The technical solutions are as varied as the materials. Depending on the raw material, application and water content involved, we design and manufacture the right rotary dryer system for customers.
In addition to a precisely controlled drying process, another important factor for drying biomass is a facility's cost-effectiveness – making use of free waste heat.
Dongding biomass drying systems are designed to be robust and easy to control.

Rotary Drum Dryer Working Principle

Firstly, wet material is crushed by the crushing machine(if needed), transported to the screw conveyor by the belt conveyor, then go into the rotary drum.
After drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector,
where the dust will be collected, with the function of induced draft fan, the left material will discharged through the conveyor.
