If you need a dryer ,you have surely waded through the plethora of options on the market today .How will you ever choose the best one for your application .
Here to inform you the most affordable and economic choice when considering a new dryer .
Rotary drum dryer also named rotary drying machine ,rotary cylinder dryer ,rotary drying machines ,which is the work horse in the industrial drying field .
What ?!
What is a rotary drum dryer ?
Rotary drum dryer also is named rotary drying machine, rotary cylinder dryer, rotary drying machines which is widely used in the industrial drying field.
A rotary dryer, or rotary drum dryer, is a slightly inclined rotating horizontal cylinder that uses a supply of heat to continuously dry a solid material. As the drum/Cylinder rotates, wet solids are fed into the inlet end and slowly make their way to the discharge end. The inside of the drum dryer includes flights designed to lift and/or mix the material inside. This helps promote heat transfer efficiency in the material.
Why ?!
Why choose the rotary drum dryer for sludge dewatering ?
The purpose of sludge dewatering is for waste minimization and to achieve overall cost efficiency for disposal .Additionally ,it can also help with a company’s sustainability objectives .Generally both the public and private sectors are required to dispose of sludge in a manner that is approved by regulatory agencies,and are in line with their own organizational requirements and environmental safe .
Sludge dewatering is typically focused on reducing the weight and volume of the sludge so that disposal costs-including transportation are kept to minimum .Water removal is the primary means of volume reduction before sludge waste can be treated of disposal of in the most economical manner .
Which ?!
The heat energy for drying is supplied in two basic ways.
The first is by heating air or gases and blowing them directly into the drum where they come in contact with the wet material. This type of drum is called a direct-fired rotary dryer and the hot gas stream either flows in the same direction as the material moving through the drum (co-current flow) or opposite to the material movement (counter-current flow).
The second method of heat delivery is by heating the shell of the drum and is called an indirect-fired dryer. This is done using jacket heaters (steam jacketed, etc.) or by encasing the rotating drum in a furnace. Either way, the atmosphere inside the drum is controlled, protecting the material from certain gases.
Rotary drum dryers are chosen by industry for their dependability and low cost. Not only are they rugged, but they are also a reliable method for producing consistent product when feed stock may vary. In addition, rotary drum dryers allow
