High Efficiency Building Material Chicken Manure Small Rotary Drum Tumble Dryer for Sludge
Introduction
The tumble dryer (rotary dryer) is simply a dryer that handles a large amount of material. Rotary drum dryers are generally suitable for granular materials, and can also be used to partially mix materials to dry viscous paste materials or materials with high moisture content. His advantages are large production capacity, wide application range, small flow resistance, large allowable fluctuation range in operation, and easy operation.

Application
The Rotary Drier is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is made of rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
Features
1) The drying strength is high, and since the materials are highly
dispersed in the gas stream, the entire surface of the particles is
actively dry and effective.
2) Short drying time.
3) The air dryer has a simple structure, a small footprint, and is
easy to build and maintain.
4) Large amount of processing, high thermal efficiency. When drying
unbound water, the thermal efficiency can reach 60%.
5) The dryer achieves "zero horizontal thrust", which greatly
reduces the wear of the brace wheel and ensures smooth and reliable
operation of the barrel.
6) Dryer adopts "aligning roller device", so that the support of
the roller and the roller will always be in linear contact, thus
greatly reducing wear and power loss.
