What is a drum dryer machine?

The drum rotary dryer can also be called H series of rotary dryer. It’s an equipment for heating and drying materials, and the drum dryer design of sleeve structure can shorten the length of dryer. Since the heat dissipation area is greatly reduced, the heat consumption is reduced, and the doubled heat exchange area greatly improves the thermal efficiency. The drum dryer machine produced from China FTM has high mechanization degree, large production capacity, excellent structure, stable convenient operation. The rotary dryer capacity can reach 0.5-50t/h.

Drum dryer has a simple structure and is favored by the customers not only in industrial production but also in daily life. Different drum dryers with different sizes have different productivity and FTM Machinery can customize the product according to your needs. Rotary dryer is one high efficient drying machine with multi-usage. In addition, cylinder dryer has the typical advantages like wide range application, energy saving, environmental benefit and other advantages.

Fote Machinery rotary drum dryer is applied to dry materials in cement, mining, building materials, chemical industry, compound fertilizer production and other industries. Drum dryer parts are device, former and rear roller device, feeding and discharge device, conveying device, gear cover and so on.

Features of drum dryer equipment

  • The temperature of finished materials is less than 50℃ and they can be put into the feed library directly without cooling in the cooling shed.

  • The drum dryer is well sealed and the heat will not be emitted. You can install the drum dryer within 2 hours.

  • The traditional drum dryer has a thermal efficiency of only 32%. The new drum dryer’s thermal efficiency has been reached to 80%, which has improved by 48%.

  • It reduces the floor space by about 50% compared to the single-cylinder dryer, and the civil construction investment is reduced by about 50%.

  • The drum dryer can save 40% of electricity. Small rotary dryer annually can save coal 50-100 million, while large rotary dryer can save coal 1 million to 2 million.

  • The raw material is delivered smoothly through the cylinder, which improves the uniformity of material and increases its residence time. In addition, the efficiency of drum dryer has been improved a lot.

  • For materials with 30% initial water content, it can be dried to less than 1% through the drum dryer.

How does a rotary dryer work?

The material input into the drum dryer, it will contact the hot air flow and begin the drying process. The material is added from the higher end, the heat carrier enters from the lower end, countercurrent with the material. However, there is also a heat carrier and material that flow into the cylinder together. The wet material will directly or indirectly get the heat from the heat carrier and will be dryer finally. Then, the dried material will be output through the conveyor belt or screw conveyor.

The copy board equipped on the inner wall of the drum will constantly pick up the material, which will accelerate the heat exchange between hot gas and slag. Besides, a cleaning device is also provided to clean the resulting agglomerates and the material adhered to the wall in order to prevent clogging.

After the heat carrier passes through the dryer, it is generally required to collect the materials in the gas by a cyclone. If you want to further reduce the dust content of the exhaust gas, you should also discharge it after passing the bag filter or wet dust collector.
