Electric rotary dryer Introduction
Electric rotary dryer is a kind of equipment widely used in industrial production, mainly used to remove moisture from materials and achieve material drying. It uses a rotating container and hot air circulation system to evaporate the moisture in the material in an efficient way to make the material reach the required degree of dryness. The rotation of this dryer is driven by a stepper motor controlled by a microprocessor, ensuring precise control of the drying process. The rotary dryer is suitable for drying various granular, powdery and granular materials. Its working principle is based on a continuously rotating drying tower and a uniquely designed nozzle system.
Functional characteristics of electric rotary dryer

Stable and Reliable
The electric rotary dryer is manufactured using high-quality materials and advanced processes, ensuring high durability and reliability. The equipment operates stably and reliably, capable of continuous long-term operation, reducing the failure rate and maintenance costs.
The structure of electric rotary dryer
Support Frame
Provides stable support for the entire equipment, ensuring that the device operates steadily and reliably.
Drying Drum
The core component of the equipment, usually cylindrical in shape, with perforations on its surface to allow heat exchange between the hot air and the material. As the drum rotates, materials move forward continuously and are subjected to hot air, achieving the drying process.
Motor
The power source for rotating the drying drum. It transmits power to the drum via transmission devices such as chains or belts, making the drum rotate at a specified speed.
Transmission Mechanism
Includes components such as a reducer, gears, and chains, which transfer the motor's power to the drying drum and allow speed adjustments.
Heating System
Provides the heat source for the dryer. It typically includes combustion devices or heaters. The heating system generates heat through fuel combustion or electrical energy and transfers this heat to the material via a hot air circulation system.
Ventilation System
Comprises fans, air inlets, and air outlets, used to introduce cool air into the dryer and expel the humid and hot air generated during the drying process. The ventilation system ensures uniform heating and drying of the material through well-designed airflow.
Control System
Manages and monitors the operation of the equipment, including temperature control, speed control, and fault alarms. The control system typically uses automated control technology for intelligent operation of the equipment.
Feeding and Discharging Devices
The feeding device introduces the material to be dried into the drying drum, while the discharging device removes the dried material from the drum. These two devices work together to ensure continuous feeding and discharging of materials, enabling the continuous operation of the equipment.
Main advantages of electric rotary dryer
