what is a rotary dryer and who use it ? Municipal Sludge Drying
Municipal sludge relates to people living environment and health. It is necessary dry them. However, municipal sludge is high humidity and strong viscosity and easily to bond again, traditional drying machine can`t dry it completely.
Our drying equipment is triple stage and multi-loop rotary dryer for municipal sludge. We specially designed rotary harrow, hot air distributor and discharging system, W type guiding and lifting boards, S Type transporting way, three levels cylinders etc, and have over 100 patent technology. With the combination function, it efficiently prevents sludge bonding again or bonding to the cylinders, heating energy is fully used, drying speed largely increased, thus sludge will be dry more completely as request!
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 for zones within the drum to perform multiple processes. For example, a single rotary drum may include a zone for drying and a later zone for classifying.
Applications ?!
Typical Materials Dried in a Rotary Drum Dryer
--- Fertilizers
--- Sludge dewatering
--- Biomass - Wood Chips, Energy Crops, and Other Materials
--- Minerals - Sands, Clays, and Other Minerals
--- Sewage Sludge
--- Animal Feeds - Cereal Grains, High Protein, Wastes, and By-Products
--- Foods - Cereals, Fruits and Vegetables, Starches, and more
Here is the point !
If you are in need of rotary drum dryer for drying wet material, please supply more of your requirement information as follows:
--- The features of raw material, for example the wet sand has surface water which is easier to be dried, but the wood chips has inner water which is more difficult to be dried.
--- Initial moisture content(%) of the wet material.
--- Output moisture content(%) the dried material needed.
--- Bulk density (kg per cubic meter) of the wet material.
--- Input capacity (ton per hour).
--- Output capacity(ton per hour).
--- Fuel Choice such as coal, waste wood, natural gas, diesel, etc.
--- End use of the dried product.
