Rotary Drum Dryer

Posted in: , on 31. Oct. 2006 - 18:03

We are looking for the Rotary Drum Dryer to dry 5TPH (tons per hour) of softwood sawdust.

Input is 50% moisture

Output 10% moisture

Heater unit to use either sowdust or most preferable bark.

Looking forward to your comments and offers.

Thanks in advance!

Dear Serge:

If you are interested in looking at Fluid Bed Drying technology, Ventilex could potentially dry your product at lower temperatures, with less equipment footprint, and lower energy costs. Also would give you a much more even and uniform moisture output with our plug flow design.

We do not manufacture Rotary Drum dryers, but if you are interested in a potentially better solution let me know.

I can not offer you a drum dryer, as you know it. I can offer you a paddle dryer, utilizing either steam or hot oil as the heat source. The dryer uses indirect heat to dry your product, eliminating the potential for fires in the dryer. It is the most energy efficient dryer you can buy, bar none. It requires no airflow through the dryer, so no loss of heat and no collection cyclones or baghouses are required. Drying 5 tph would fit in a small footprint. If you are interested in discussing this further, you can contact me at

Best Practices For Eucalyptus Bark Drying

Posted on 7. Dec. 2006 - 01:36

Dear forum members, we, at PRAXIA, have the same request of Mr. Necser to find which could be the best way to dry eucalyptus bark. The purpose is to use the biomass as the secondary fuel in a cement kiln, which is already burning petroleum coke. We should be able to dry 20t/h@55% moisture (WB) to final moisture of 10%. The bark particles will be blown in the burner, so final particle sixe to be less than 1mm diameter, less than 8mm long.

Bark size (input for dryer) will depend on dryer type. We do not want to use a rotary kiln because of two reasons:

1) Very high investment required

2) Too large footprint.

Dryer complexity increases with particle size increase.

Milling energy requirements increase dramatically with moisture content.

So, there will always be a solution of compromise between these two processes

We have thought in two alternatives:

a) Rod mill grinder which combines both milling and drying processes. Test results are very promising.

b) Grain (seeds) vertical dryer (yet to be tested)

We have disregarded a pneumatic conveying dryer (Flash dryer) because of the particle size required, too much energy and complexity to reach particles < 1mm diameter prior to drying.

Any help any of you can gently supply us with will be highly appreciated. We have attached a photo of how the raw material looks like (left side material in the photo).
