Drying drum

Appointment

The drying drum is designed to evaporate moisture from sawdust or microchips and obtain a material with a moisture content of less than 10%. The drying drum works in conjunction with a pneumatic conveyor and a heat generator.

Characteristic

The drying drum consists of three main components: a drum, a drive with rollers mounted on a common frame, a collector for loading and unloading material.

• Specific fuel consumption – 186 kg per ton of pellets
• Electricity (total) – about 263 kW per ton of pellets
• Raw materials – about 1.95 tons of crude wood chips per ton of pellets

The principle of operation

The drying drum is mounted on 4 support rollers, 2 of which are mechanically connected to the drive of the drying drum. When the drive is running, the drum rotates at a frequency of 8-9 rpm. Due to the rotation of the drum, the chips (sawdust) are mixed with hot gas (drying agent up to 300°). When the raw material is heated, moisture evaporates from the material.

Advantages

• The simplicity of the design.
• High performance.
• Automation of all processes.
• No difficulties with installation, commissioning.
