Drying Treatment System (Electric drying equipment)

1. Structure and Principle
Dryer heat source is electric heating strip, equipped in the dryer barrel outer body. Dryer shell has insulation layer, a rotatable stirrer is installed in the dryer body. Electric heating strips are used to generate high temperature heat to dry sludge by heat conduction. The system design uses closed fit operation, dust filtration system to accelerate the drying process by sucking out wet air and filtering dust.

2. Purpose

• High-performance drying equipment, the high moisture content of wet sludge, dried reduction to low moisture content of sludge.
• Organic sludge and inorganic sludge best drying reduction equipment.
• Suitable for paste, pasty and powder materials drying and reducing.
• Application of the low moisture content of the sludge drying quickly.

3. Features
Chemical sludge and bio-solids best drying reduction system, simple operation and good effect, fast drying process. Dryer has "sealed package" seal on the propeller stirrer bearing to prevent sludge and moisture from entering the bearing.

4. Specification and Functions
All internal parts are made of stainless steel, with a propeller stirrer blade moves back and forth inside and outside the sludge. The system employs a batch operation, the drying capacity is designed according to customer demand, control system automatically operating the drying process.
