Apr 01, 2016· Mark off four spots — two each on the horizontal and vertical axes. Measure from 1 to 3, the vertical axis, and then 2 to 4, the horizontal axis, as shown in the figure. Next,rotatethe drum 90° and measure from 1 to 3, which is now on the horizontal axis, and 2 to 4, which is now on the vertical axis.
In therotary drum dryer process,combusted gases mixwith clean, heated air. The wet bulk material is propelled through the system via a hot gas air stream. The material is continuously lifted by the cylinder flights and showered through the concurrent stream of hot gases.
The flighting in arotary drum dryer systemcan be changed to repurpose a used or existingdryer. A flighting designer can look at the flow characteristics of the material in question and determine what kind of flights are necessary, thereby converting thedryerto a newpurposeat a fraction of the cost of buying a newdryer.
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.
The majority of maintenance, repair and redesign jobs for rotary drum dryers are centered around reducing fugitive air (also called tramp air) or repairing drum structural problems. Almost all rotary drum dryers are set up as negative pressure systems, which means the dryer sucks in air if given the chance.

Rotary Drum Dryer Machine Working Principle 1. Drum type dryer is mainly composed of rotary body, lifting blade, transmission device, supporting device, sealing ring and other components. 2. Wet materials are transferred to the hopper by belt conveyor or bucket elevator, then going through the charging pipe and going into the drying body.
Apr 27, 2007· The effectiveness of the rotary drum drying process depends primarily on the contact between the cascading particles and the drying gases within the drum. This paper considers first the factors which contribute to the cascade pattern and which influence the design of the lifting flights which distribute the particles in the top half of the drum. A generalised calculation design procedure for …
