Rotary Dryer

Introduction:Rotary Dryer has many names in the industry, which is often referred to as the rotary drum dryer and rotary dryer machine. Rotary Dryer is the most commonly used drying equipment among mining equipment.

Rotary Dryer Overview

Rotary Dryer has many names in the industry, which is often referred to as the rotary drum dryer and rotary dryer machine. Rotary Dryer is the most commonly used drying equipment among mining equipment, which is widely used to dry slag, limestone, coal, clay, grain, compound fertilizer, etc., in mining industry, metallurgy industry, chemical industry, building materials, compound fertilizer production and cement industry. It is suitable for drying metallic and non-metallic minerals, the magnetic, heavy and floating concentrate, clay of cement industry as well as coal slime in coal industry.

Performance Features of Rotary Dryer

The machine mainly consists of rotary machine, raising plate, transmission device, supporting device and seal rings and other components. The dry machines in our company use the new-type raising plate, which has the functions of guiding, even flow, raising materials etc. The raising plate can make the materials be distributed uniformly to the cross profile in the dryer machine. The material curtain is at the state of thin, even and complete, with completely touching with the hot air flow to reach the purpose of making full use of the heat energy. The consumption of coal and electricity of the dryer in our company can be lower 10% to 15% than the normal dryers, with the production ratio higher than 10% to 15%.

The Usage of Rotary Dryer

Rotary dryer is a kind of drying machine which can handle a large number of materials. Because of its reliable performance, flexible operation, strong adaptability and large capacity, rotary dryer is widely used in metallurgy industry, building materials industry, light industry, chemical industry, coal, mining industry and medicine industry. Rotary drum dryer is generally adapted to granular materials, and it can also be used for drying sticky and paste materials or materials with high water content.

Rotary Dryer Structure Rotary Dryer/Rotary Dryer Machine

Rotary Dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.

Working Principle of Rotary Dryer/Rotary Dryer Machine

Rotary dryer is mainly composed of rotary part, lifting board, transmission part, supporting part and seal ring. Since the dryer machine is obliquely installed, the materials flow to the lower end of the machine under the gravity and the rotation of the machine, and on the other hand, the materials are repeatedly lifted by the lifting board to the higher end and then spread down constantly, so that the materials will form a even curtain inside the cylinder and conduct heat exchange with the hot air inside the cylinder. Since the materials constantly spread and the water contained in them will be dried, thus achieving the aim of drying.
