The rotary dryer is a type of industrial dryer used to reduce or minimize the moisture content of the material it is handling by bringing it into contact with a heated gas. The dryer is made up of a rotating cylinder ( drum or shell ), a drive mechanism, and a support structure (commonly concrete posts or a steel frame). The cylinder is inclined slightly with the discharge end is lower than ...Get Price

Jun 01, 2016 Rotary Dryer – Kiln. Of the different types of dryers that there are the most common is the ROTARY DRUM DRYER/Kiln, This type of drier is common not only in the mining industry but you will find them in fertilizer plants, Cement plants, and peat hogs to name but a few.
Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum.
12.2.3 Rate of evaporation in drum dryers T he rate of moisture removal by a drum dryer is essentially a constant rate of water evaporation as the product is continuously fed between the drums and the dried product is removed. The equation governing the rate of evaporation in a drum dryer is: Where, = ts - ta latent heat of vaporization.
CONSTRUCTION : DRUM :- The material of the drum could be Mild Steel, or any grade of Stainless Steel with or without Hard Chrome plating. The surface of the drum is machined and ground. The drums rotate on antifriction self-aligning ball / roller bearing with standard Housing. SCRAPPER :- The Scrapper Knife scrapes off the … Continue reading Double Drum Dryer

A double-drum dryer consists of two cylinders (drums) of equal diameter rotating very close together in opposite directions. The material to be dried is fed into the wedge-shaped space between the drums using a distribution pipe. Heat is transferred from the hot drum surfaces to the wet material.
The drum dryer mainly is one large rotating cylindrical tube, and the wet material is taken into direct contact with the hot flue gas in the large rotating cylindrical tube. On the inner wall of the large rotating cylindrical tube, there are many welded lifting boards in a certain slope.
