Product Introduction

Rotary drum dryer is reliable in operation, flexible in operation, strong in adaptability, and large in processing capacity. Rotary drum dryer is widely used in metallurgy, building materials, chemicals, coal washing, fertilizer, ore, sand, clay, kaolin, sugar, etc. The field, diameter and length are determined according to the drying requirements.

Working principle

Rotary drum dryer wet material enters the drying cylinder through the conveyor and is repeatedly raised and thrown down by the lifting plate on the wall of the rotating cylinder. During the falling process, it scatters into fine particles. The heated area is greatly increased, and it is fully contacted with hot air for drying.
