The so-called sludge dryer is also suitable for municipal sludge drying. The single-channel rotary dryer is a new type of equipment developed on ordinary rotary dryers . The internal installation deagglomerating mechanism, movable purlin wing panel, cleaning device and crushing and strong device can dry the viscous material that the ordinary rotary dryer can't handle. For the sludge has a certain viscosity, small particle size and other characteristics, single-channel dryer is the best choice. Using a single-channel rotary dryer, downstream process, using a specially designed feeding device, the sludge quickly enters the dryer and exchanges heat with high-temperature hot flue gas, forming a hard shell on the surface. Reducing sludge sticking to the barrel and blocking material. In the 1/4 section of the dryer head, besides the installation of the lifting plate, the deagglomeration mechanism with reinforced evaporation and the linked purlin wing panel are installed, which can not only transmit heat but also prevent the mud from sticking to the cylinder and The lifting plate, taking full advantage of the fast drying rate at the feed end, realizes a method of “stripping” the layers so that they can be quickly dried.

When the sludge dryer dries various sludges, the two-axis rotary vane dryer (vertical, horizontal) and three-axis rotary vane dryer (horizontal type) can be used according to the viscosity of the sludge. The moisture content of 85% or less of high-humidity materials is once dried until the final water content is below 12%, and the drying time is short, generally 2-10 minutes. Due to the intense stirring of the wet material by the high-speed stirring blades, the wet material can be in good contact with the hot air. In the first half of the machine, moisture evaporates quickly and the temperature of hot air in the machine drops sharply. Therefore, even if high-temperature hot air is used, the temperature rise of the material is not high. Typical applications include electroplating sludge drying, paper sludge drying, oil field sludge drying, chemical sludge drying, sludge drying, fruit residue drying, bean dregs drying, sugar residue drying, peat drying, rare earth and other high humidity materials drying, organic, Inorganic compounds and chemical raw materials such as mud, powder granular, sheet-like high-humidity materials are dried.
