Customized Rotary Drum Dryer Industrial Rotary Drum Sludge Drying Equipment

Principle

After been filtered and heated the air enters into the air distrbutor on the top of the dryer.The hot air enters into the drying room in the spiral form and uniformly. Passing through the high-speed centrifugal sprayer on the top of the tower,the material liquid will rotate and be sprayed into the extremely fine mist liquid beads.Trough the very short time of contacting the heat air,the materials can be dried into the final products.The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower.

Features

1.compact structure, effective heat transfer area, small area

2.The mixing is uniform, high thermal efficiency, good drying effect

3.the blade shaft can mesh with each other, with self-cleaning effect, can prevent the material wall

4.Even of low energy consumption, small operating costs

5.small dust entrainment, less material loss

6.Indirect heating, no material pollution

7.The low rotation speed of liraglug impeller shaft, does not damage the product shape and properties

8.Therefore the device to operate flexible, smooth and reliable operation

Centrifugal spray atomizer Features

1.The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.In the hot-air flow,95%-98% of water can be evaporated at a moment.The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials.
2. Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.
3. The production procedures are simple and the operation and control are easy.The liquid with moisture contents of 40-60%(for special materials,the contents might be up to 90%).can be dried into the powder or particle products once a time. After the drying process, there is no need for smashing and sorting,so as to reduce the operation procedures in the production and to enhance the product purity.The product particle diameters,looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient to carry out control and managment.
