Three return dryer

Product Introduction

Three-drum dryer is also called three-cylinder dryer and triple-drum dryer. It has improved internal structure of monocular dryer, which prolongs the time of pre-drying of wet materials and wet materials in the machine, thus improving 50% to 80% of production capacity compared with original monocular dryer.

Applied materials

Rock, gravel, different kinds of ore, fireclay, slag and other hard materials.

Features

• The moisture is controllable;
• Multi-channel intelligent anti-ignition;
• Reliable fire handling equipment;
• Coal & power saving, various heat sources can be used;
• Full automatic control;
• Pollution-free emission.
