Appliable Materials: blast furnace slag,fly ash,cinder,sand,quartz sand,clay raw materials etc.
Rotary dryer is mainly composed of rotating body, lifting plate, transmission device, supporting device and sealing ring. It is generally suitable for granular materials, and can also be used for semi-dry viscous paste materials or partially mixed materials, and materials with higher water content. Rotary dryer has the advantages of wide application range, convenient operation and high operation rate. It is widely used in the cement industry to dry raw materials such as clay, slag, gravel, and coal...Learn More

This equipment adopts steam as heat media and indirect heat conduction all amount of heat is used for heating materials washing force is produced by the relavant
It can be mainly used for thedrying of slurry paste granular powder fiber easily oxidized heat sensitive materials the main characteristics 1compact structure effective heat transfer area small area 2the mixing is uniform high thermal efficiency good drying effect
Vented dryer steam heating with individually programmable controls for the maximum in flexibility less folding easy finishing laundry is dried very gently and evenly in the honeycomb drum low energy consumption and quick drying for large textiles the miele perfectdry system dries garments perfectly
Pt 8807 ptm d arp vented dryer steam heating with individually programmable controls for the maximum in flexibility
Drum dryers system the sakav steam heated drum dryer is noted for its high thermal efficiency in the removal of water andor solvents from a wide range of solutions slurries and suspensions
The liquid feed of a drum dryer is applied onto one or more slowly rotating steamheated rolls the dried product is removed by a knifelike mechanism drum dryers are primarily used to dry slurries and pastes they are available in several types single drum double drum double drum vacuum and twin drum
This is problematic in drying because moisture pulled from the material naturally cools the heating medium so if saturated steam were to be used it would quickly condense and rain in the drum because steam is so close to the temperature at which it condenses this problem is avoided by using superheated steam as the drying medium
Raw material fed by the screw conveyor is dried by mixing in the rotating dryer and is transported down along the inclined dryer then discharged from the discharge chutes placed around the circumferential shell steam flow steam is supplied from a steam neck
The drum dryer has excellent thermal efficiency making it the optimal dryer for directly solidifying and drying liquid or sludge type materials the drum dryer consumes 12 to 14 kg of steam to evaporate 1 kg of moisture this thermal efficiency is much better than a spray dryer making it an energy saving dryer
Jul 28 2020 material is fed into the drum and tumbles over the outside of the inner tubes inside those tubes steam is collapsing to condensate the latent heat from the steamabout 850 btus per poundprovides the heat energy for drying the condensate from the steam is removed through a
Find out the evaporation rate in a drum dryer for given data steam temperature 150 c vapourisation temperature of milk 103 c overall heat transfer coefficient 13 kw m 2 k drum diameter 60 cm length of the drum 100 cm latent heat of vapourisation 2261 kj kg the product is scraped at of a revolution of the drum
As the drum rotates lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency when working with agglomerates the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules
Typical results show that the use of air hoods with moderate temperature air and with a reduced steam pres sure in the drums lead to a reduction in maximum product temperature from a value of 250
Oct 18 2010 gea barrrosin energyefficient superheated steam dryer ssd is an indirectheated pneumatic dryer in which water in the product produces steam at 05 to 4 bar gauge pressure there is no air or flue gas in contact with the product and no emissions to the atmosphere produced
Discover the latest features and innovations available in the 75 cu ft electric dryer with steam sanitize in white find the perfect dryers for you
Apr 09 2019 the traditional steam tube rotary dryer or steam calciner has a steam drum at one end and the steam heat exchange tubes in the dryer are connected the steam drum is steamdistributed and hydrophobic by a steam drum the connection between the steam heat exchange tube and the steam drum is subject to inspections such as hydrostatic tests which are generally carried out at the factory
May 18 2016 8 the drum dryer is an indirect type dryer in which the milk to be dried is maintained in a thin film on a rotating steam heated drum the milk being dried is spread over the outside surface of the dryer clinging to it and drying continues as the hot drum rotates
The supply steam is condensed in the heat exchanger and leave the dryer through the condensate outlet 14 a higher supply steam pressure will heat the circulating steam to a higher temperature which again will increase the capacity of the dryer
the system comprises of rotating shell with tubes inside having highpressure steam flowing through the material passes over the tubes and is heated with steam resulting in very high heat transfer high thermal efficiency this units are manufactured in heavy duty construction can handle large capacity
Help keep wrinkles from setting into clean dry fabrics the wrinkle shield plus option with steam uses tumbling and steam for up to 150 minutes after the cycle ends or until you open the dryer door for improved wrinklefighting performance
Apr 01 2016 some dryer manufacturers recommend a high temperature rubber belting however a high temperature belting still should not be used in temperatures higher than 400f 204c the gases at the front of the drum can be in excess of 1000f 537c which will burn up a seal in a matter of hours after installation without a heat shield
Oct 06 2019 the steam feature creates steam in the dryer independent of a traditional drying cycle steam drying is used to freshen clothes that are wrinkled or have strong odors these dryers require a water line or have a water reservoir that must be filled manually and an additional heating element for the water to create the steam mist
