Drying Wood Rotary Drum Dryer Equipment

13 Tons Per Hour Particle’s drum dryer for Paticle Board Production Line

7~35 Tons Per Hour Particle’s drum dryer for Paticle Board Production Line

Description

rotary drum dryer machine belongs to a new generation of wood drying equipment, also known as shavings dryer, which is designed for wood chips /wood flakes drying. There are two main streams in wood drying equipment: hot air dryer (also called wood chip dryer or sawdust dryer) and single-channel rotary dryer (that is, for the wet shavings played by the shavings machine and the wood chips played by the chipper, also called shavings dryer, wood chip dryer).

This series of shavings /chips /flakes /sawdust dryer can not only dry wood chips, wet shavings, grass powder, sawdust, wood chips and other biomass, but also according to the orientation of raw materials, also suitable for livestock manure, wine trough slag, grass, ginkgo leaf, blood powder, feather powder and other drying, the product absorbs the advantages of high humidity rotary dryer and air dryer, optimized combined wood drying machinery, Can maximize the saving of drying costs, compared with the use of tumble dryer, air dryer cost savings of 30%, 50%.

Wet material is fed via a rotary valve and a specially designed infeed chute into the rotating drum. There, the heat is transferred mainly through convection from the drying gases to the material for water evaporation. At the end of the drum, the material is pneumatically transported to cyclones where the material is separated from the drying gases. One portion of the drying gases is recirculated

to the mixing chamber for energy recovery and reduction of dryer exhaust volume.

Two types of drum dryer system

Main characteristics of drum dryer

• High energy efficiency, waste heat could be recycled to save energy.
• Low oxygen drying will not get fire easily, more safe.
• Particle’s shape well maintained not damaged during drying.
• Keep particle’s moisture stable.
• Large unit capacity.
