Rotary Drum Dryer

Rotary drum dryer is one of the traditional drying equipment, and it has reliable running, flexible operation, strong adaptability, and high production capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin and sugar. Its diameter is Φ 1000 – Φ 4000, and the length is depended on the dry requirements. In the center of the rotary drum dryer, increasing the dispersion mechanism can be avoided; The wet material entering into the drying cylinder is repeatedly copied and left off by the copying plate on the cylinder wall, then in the process of falling, the material is broken into fine particles by dispersator. In this way, the contact area increases greatly, and the material fully contact with the hot air, thus the effect of drying is achieved.

Brief introduction of Rotary Drum Dryer

Rotary drum dryer is one of the traditional drying equipment, and it has reliable running, flexible operation, strong adaptability, and high production capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin and sugar. Its diameter is Φ 1000 – Φ 4000, and the length is depended on the dry requirements. In the center of the rotary drum dryer, increasing the dispersion mechanism can be avoided; The wet material entering into the drying cylinder is repeatedly copied and left off by the copying plate on the cylinder wall, then in the process of falling, the material is broken into fine particles by dispersator. In this way, the contact area increases greatly, and the material fully contact with the hot air, thus the effect of drying is achieved.

Characteristics of Performance

The distribution and Angle design of lifting blade are reasonable and the performance is reliable. Therefore, the thermal efficiency is high and the drying is uniform.

The rotary drum dryer adopts the structure of the adjustable tug, then the tugboat and the rolling circle cooperate well, which greatly reduces wear and power consumption.

The specially designed retaining wheel structure greatly reduces the horizontal thrust caused by the tilt of the equipment. The anti-overload ability is strong, the cylinder body runs smoothly.

The drying machine has the characteristics of high temperature resistance and can use high temperature and hot air to dry material quickly.

The machine has high production capacity, low fuel consumption and low drying cost.

Working Principle

The rotary drum dryer is mainly composed of rotary body, lifting blade, transmission device, supporting device and sealing ring. Dry wet materials are sent to hopper by belt conveyor or bucket elevator, and then by hopper feeder the material enters the feeding end through the feeding tube. The slant of the feeding pipe is larger than the natural inclination of the material, so that the material flows into the dryer smoothly. The cylinder of dryer is a rotating cylinder slightly tilted to the horizontal line. The material is added from the higher end, the heat carrier is entered at the low end with the material in reverse contact; there are also heat carriers and materials that flow into the tube together. With the rotation of the cylinder the material is operated by gravity to the lower end. In the process of moving forward, the wet materials can be directly or indirectly heated by the heat carriers, so that the wet materials can be dried and then be sent out by belt conveyor or spiral conveyor to the discharge end.
