Information needed to design the rotary sawdust dryer

One UK rotary sawdust dryer customer said that as follows:  

I would like to discuss details of your Rotary Sawdust Dryer. We are a Alternative Fuel supplier and have 8 Biomass sites in the UK where we potentially need to dry our saw dust.

As you see, the above information is not clear, and in order to design the suitable rotary sawdust dryer, Sunco Machinery Engineer need more information as follows:

1- Before drying, what is the initial moisture content (%) of the wet sawdust ?

2- Before drying, what is the bulk density (kg per cubic meter) of the wet sawdust ?

3- After drying, what is the output moisture content (%) of the dried sawdust ?

4- How many kilogram wet sawdust do you need to use the rotary sawdust dryer to dry per hour ?

5- For the furnace, what kind of fuel will you prefer to use such as waste wood, coal, diesel, natural gas, etc?

If you are also interest in rotary sawdust dryer, please kindly give us the above information, here Sunco Machinery engineer can design the sawdust drying line according to your actual situation.
