Rotary Dryers Dealers in Kanpur

In a chemical Industry, of all the Unit Operations Drying has the widest application and a proper appreciation of the mechanism of drying and the equipment available to resolve a drying problem on an industrial scale is correspondingly important. Most manufacturing operations, particularly in the chemical and metallurgical fields, entail one or more stages where drying is one form or another is carried out. Drying costs account for a large portion of the processing costs associated with the manufacture of Chemicals, Pharmaceuticals, Dye Stuff’s and other products. A Filter Press or a Centrifuge is often used to remove as much water or solvent as possible, there by reducing the heat load in the drying process. Mostly and unfortunately the cake is normally dried in a tray dryer, where the energy consumption is excessively high. Apart from high energy costs, tray dryers also have high labor cost for loading and unloading of the product. Product loss due to manual loading and unloading long drying time and generally dirty operating area.

It is used to dry the Khaini leaves and remove the undesired moisture from it. For customer’s convenience, Rotary dryer comes in different sizes and is equipped with a dust collector to ensure less wastage. Working Principle : The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. The gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Application : Rotary Dryers have many applications but are most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulphate, filter cakes, sewage sludge, etc. It is also applied on food industry mainly for liquids as well as for granular material such as food grains, cereals, pulses, coffee beans, fermented tea leaves, etc.

We offer rotary dryer operated at almost atmospheric pressure consists of a m.s.cylindrical shell, ranging in length from four to ten times its diameter, into which the wet charge is fed continuously at one end and is discharged at the other, the movement of the material being due usually to the combined effect of inclination of the shell to the horizontal and the action of internal lifting flights during the rotation of the shell. The latter is usually provided with machined girth rings supported on suitable designed bearings. Rotation of the shell is secured by the action of suitable gearing. Hot air produced from hot air generator (direct or indirect ) is injected into the dryer to achieve the required dryness of the material . The discharge end of the rotary dryer consists of sealing arrangement , cyclone and dust collector.

Used for converting molten Slurries into dried solid flakes. In the rotary dryers material is fed into a feed hopper which directs the materials on the face of rotating drum. The drum is heated or cooled depending on the application to enable the material to cling to the outside of the drum. The material is dried during the rotation of the drum and is removed by a blade or scrapper mounted along the length of the roll. Materials processed in the drum dryer are:(1) Caustic Soda(2) Resins (3) Waxes(4) Fatty Acids (5) Guar Gum(6) Sulphur Dyes.
