For these materials, drying is used to produce a saleable product by removing the remaining moisture content, or preparing the material for a granulation process. In the case of ammonium sulfate, for example, crystals exiting the centrifuge typically contain around 1.0 2.5 moisture. The rotary dryer further reduces the moisture content to ...
The amount of moisture a material carries can influence the air flow configuration of the dryer. This refers to the direction of the air flow in relation to the flow of material co-current in the same direction or counter current in opposing directions. Materials that carry a significant amount of moisture may require fast initial drying.
Our rotary drum drying machine has good characteristics of high temperature resistance, that ensures the high temperature hot air can dry fertilizer materials quickly. And this kind of drying machine is much more efficient than the traditional dryers. 3. The distribution and angle design of the lifting plates are very reasonable, making the ...
We offer Single Shell Rotary Dryers in co-current and counter current operation. In the former the wet material is exposed to the hottest air which enables heat sensitive or sticky materials to be dried successfully. In counter current arrangement dried material exposed to hottest air helping to achieve high dry material temperature.

then go into the rotary drum, after drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, with the function of the induced draft fan, the left material will be discharged through the conveyor. Dongding Gypsum Dryer Advantages 1.
May 01, 2009 It is a sticky material with a tendency to foul drying equipment. This paper evaluates the drying behaviour of BSG in a pilot-scale rotary SHS dryer. The evaluation is based on product moisture content, measurements of sticking and energy consumption. The results of an experimental design for three system parameters steam temperature, steam ...
Aug 19, 2019 Drying equipment is a kind of mechanical equipment that uses heat to reduce the moisture of materials and is used to dry objects. The drying apparatus vaporizes moisture in the material generally referred to as moisture or other volatile liquid component by heating to obtain a solid material having a specified moisture content.
Owing to centrifugal force, the radius of larger proportion materials which havent meet requests for moisture will be enlarged. When the rotary radius of materials is longer than radius of classifier, materials will be blocked in drying chamber for further drying
About Rotary Dryer The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into ... Favorites Changzhou Fanqun Drying Equipment Co., Ltd.
Jun 01, 2016 ROTARY DRYERS, Indirect-Heat Design Capacity based on 10 moisture, wet weight, in material fed to dryer, and 3.26 pounds of moisture evaporated per hour for each cubic foot of the volume of the main cylinder. NOTE The customer furnishes and erects the brickwork setting for the dryer in accordance with drawings furnished by Equipment Company.
For special applications, the rotary cascade design is adapted to provide a shortfall, or Cruciform, lifter configuration. Features of the Rotary Drying Robust construction with various lifter options Can be co-current or counter-current
The critical moisture content is the average material moisture content at which the drying rate begins to decline. A prototype drying test should be conducted to determine the critical moisture content. In Fig. 2, the point B represents the constant-rate termination and marks the instant when the liquid water on the
Rotary Rotary dryers dry material by heated air while being transported along the interior of a rotating cylinder. ... Equipment Design Direct-heat rotary dryers dry the wet feed through direct contact with a hot gas. The gas flow can be cocurrent or countercurrent to the feed stream. ... avoiding overheating of sensitive products.
Because the primary job of a rotary dryer is to dry the material, the irst material characteristic to look at is Heat Transfer Properties the percentage of moisture the material holds in its The heat transfer properties of a material will also have raw state, as well as the desired moisture percentage an impact on dryer sizing and design.
Best for Materials that are heat-sensitive, maintaining product quality NOTE 90 of all rotary dryers are co-current for these reasons Key Advantages Greater control over solids temperature and avoidance of overheating. Disadvantages Slightly less thermally efficient than counter-current air flow. Co-current or parallel flow drying occurs ...
