A Rotary Drum Wood Sawdust Dryer is an industrial drying machine designed to reduce the moisture content of sawdust, wood chips, wood shavings, and other biomass materials. It is widely used in biomass fuel production, wood pellet plants, charcoal making, and animal bedding preparation. Fresh wood and sawdust typically contain 30-60% moisture, which is too high for pelletizing, combustion, or briquette production. A rotary dryer reduces the moisture content to 10-15%, ensuring optimal quality and efficiency.

The rotary drum dryer is a must-have equipment in large wood pellet production lines to dry wood sawdust. We offer single-cylinder rotary dryers and three-cylinder rotary dryers with capacities ranging from 1 t/h to 9 t/h. It can also be used to dry a wide range of biomass materials such as alfalfa, straw, sawdust, marigold, wood shavings, manioc waste, bagasse, colza cake, leaves, etc.

The rotary wood dryer consists of a rotating cylinder, transmission device, supporting device, shoveling plates, etc. The rotary drum dryer is a horizontal-type drying device. Our wood drying machines are reasonably designed and have a large drying capacity of 1-9t/h. There are shoveling plates at different angles welded throughout the inner side of the whole drum. The feeding place is set with door ring and rotary shoveling plates to avoid materials splashing.

The three-cylinder rotary dryer is suitable for drying raw materials with high specific gravity, like sawdust, sludge, etc., with a capacity of 1t/h to 6 t/h.

The single-cylinder rotary dryer is suitable for raw materials with low specific gravity, like leaves, straw, beet leaves, etc., with a capacity of 1t/h to 9 t/h.

✅ Efficient Moisture Reduction – It lowers moisture content from 30-60% to 10-15%.
✅ Continuous Operation – Large-scale industrial dryers run 24/7 for high production efficiency.
✅ Uniform Drying – The rotating drum ensures consistent heat distribution. Stable drying process.
✅ Energy Efficient – Uses waste wood, gas, coal, or electricity for heat generation. Low energy consumption and operation cost.
✅ Adjustable Drying Time & Temperature – Can be customized for different biomass materials.
✅ Versatile Fuel Options – Compatible with biomass burners, steam boilers, natural gas, and coal furnaces.
✅ Economic space occupation, easy to install and maintain.

1. Biomass Pellet & Briquette Production
Prepares wood sawdust, shavings, and chips for pelletizing and briquetting. Ensures low-moisture fuel for biomass stoves, boilers, and power plants.
2. Charcoal & Biochar Manufacturing
Dries wood materials for charcoal and activated carbon production.
3. Animal Bedding & Composting
Dries sawdust, straw, and organic waste for livestock bedding and compost.
4. Paper & Pulp Industry
Reduces moisture in wood fibers and recycled paper for processing.
5. Mine And Chemical industry
Applied for all kinds of pellet and powder materials. Used for drying wet materials such as blastfurnace slag, slunch, limestone, pulverized coal, ore, and quartz stone.

A Small Rotary Wood Sawdust Drying Line Was Launched

A Rotary Drum Dryer operates by using hot air to evaporate moisture from sawdust while continuously rotating the drum for even drying. Biomass materials with high moisture content are fed into the rotary cylinder; shovelling plates inside the drum walls raise materials, and these materials scatter down to move in a spiral forward style, during the constant raising up and scattering down to achieve the best drying effects.
