Introduction

Rotary Dryer is an industrial-grade drying machine designed for continuous drying of materials with high moisture content. It consists of a large rotating drum driven by a motor, with an internal lifting plate structure that constantly lifts and scatters materials, enhancing heat exchange between the hot gas and the material. The system uses direct or indirect heating methods depending on material characteristics. Rotary Dryer is capable of handling a wide range of materials such as mineral concentrates, coal slurry, limestone, sand, and clay. With adjustable inclination and rotation speed, it provides flexible control over residence time and drying intensity. The machine is easy to operate and maintain, with features like uniform drying, high thermal efficiency, energy saving, and long service life. Widely used in mining, metallurgy, building materials, cement, chemical, and other industries, Rotary Dryer plays a vital role in material preparation and process optimization.

Working Principle

Rotary Dryer works by using a rotating drum to lift and tumble material through a stream of hot air. Wet material is fed into the dryer from one end. As the drum rotates, internal lifting plates continuously raise and scatter the material, increasing the contact surface with the hot gas flow. The heat causes moisture to evaporate, and dried material is gradually pushed toward the discharge end by the rotation and gravity. Moisture-laden exhaust gas exits from the opposite end, often treated by a dust removal system before release. This process ensures continuous, efficient, and uniform drying.

Features

Application

Wide Applicability

Strong adaptability to materials, suitable for energy-saving drying of various powder, granular, strip, and block materials. It can not only quickly remove moisture from materials, but also has simple and reliable equipment operation

Strong Drying Ability

Adopting a new type of multi combination lifting device, it has multiple functions such as guidance, uniform flow, and lifting, which can effectively overcome the "wind tunnel" phenomenon of traditional dryers, allowing materials to fully contact the hot air flow, and the drying heat transfer process is strong and efficient

Excellent Material Selection

The cylinder body is made of steel material, which has high hardness, toughness, and is more wear-resistant; The transmission of large and small gears adopts pin column replaceable gears, with low investment cost. There are multiple lubrication methods for the supporting wheels, effectively extending the service life

Less Dust Leakage

Good sealing performance, complete dust removal device, effectively reducing dust leakage; Reasonable operating parameters, effective utilization of thermal energy, reduction of coal and electricity consumption, and improvement of production capacity
