sand rotary dryer

Working principle

Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.

Overview

Rotary drier is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature
Rotary drier is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc. (Optional auxiliary equipment includes combustion chamber, feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us adopts new lifting plate, which is of functions like guiding, current-sharing, and material rising. The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. Our rotary drier is designed with the best working conditions, which enables it to save 10-15% of energy and increase 10-15% of productivity compared with common dryers.

Feature

High heat transfer coefficient and high thermal efficiency
• Large treatment capability, wide application
• Well drying effect
• Indirect-heating, no material contamination
• Retention time can be adjusted, low energy consumption
• Convenient operation and easy maintenance

Brief introduction

Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industry and coal in coal mine, etc. Rotary dryer can be widely used to dry various materials, and it is simple to be operated.
