drum dryer temperature after granulation
drum dryer,fertilizer granulator,fertilizer granulating machine. Introduction of Rotary Drum Cooling Machine. Our rotary drum cooling machine is regularly used to cool fertilizers with a certain temperature and granularity in compound fertilizer production lines.The inlet temperature of materials generally is 60 °~ 80°, the outlet temperature is less than 40°.
The TURBO-DRYER ® consists of a stack of slowly rotating circular trays. Material is fed onto the top tray. After one revolution the material is wiped onto the next lower tray where it is mixed, leveled, and then after one revolution, is wiped to the next tray where the operation is repeated.
4. After gasification of gas ammonia and steam, the mixture distributor enters the feed layer and reacts with monoammonium phosphate and calcium superphosphate in the feed layer in the rotary drum granulator.At the same time, the reaction heat is released, and the dry and wet materials are agglomerated and granulated under the rotating action of the granulator.
When choosing drying equipment and granulation machines, there are a number of things to consider. Do you need a freeze dryer that produces finely dried powder or will the less expensive drum dryer that creates flakes suffice?
A process for preparing granulated fertilizer materials, wherein urea phosphate is used as a granulating agent to assist in the agglomeration of finely divided solid particles into relatively uniformly sized granules. Urea phosphate, prepared by dissolving urea in phosphoric acid, is coated onto finely divided particles of fertilizer materials, and granulation is accomplished at a temperature ...
May 09, 2016· The pilot-scale granulation was achieved within the drum of a superheated steam dryer, thus enabling the simultaneous granulation and drying of the granular product. Superheated steam drying provides an intrinsically safe method for drying BC which has a propensity to undergo spontaneous combustion.

Microwave Drying. Microwave drying is a method gaining popularity owing to its superior advantages such as high heating rates, significant reduction in cooking time, more uniform heating, safe handling, ease of operation, and low maintenance in a small extent of sensory and nutritional changes compared with conventional thermal applications (Salazar-González et al., 2012; Vadivambal and Jayas ...
Importance of Inlet Air Velocity in Fluid Bed Drying of a Granulation Prepared in a High Shear Granulator ... discharged to a fiber drum. As seen in Table 2, ... temperature vs drying time profile ...
After granulating, the granules need to be dried. Belt conveyor transport the granules to the rotary drum drier. The drying machine removes moisture from the particles to increase the intensity of granules. Thus, it is convenient for storage. After drying, the temperature of fertilizer granules is too high to agglomerate.

After the granulation process, the particles will be sent into the Rotary Drum Drying Machine. 5. Rotary Drum Dryer: During the drying process, the water contents of granulated particles will be dried, so that the particles will be harder and easier to store. The body of the machine is a slightly inclined rotary drum compared with the ...
the drum, in order to achieve the desired average drying-air temperature. All in all, the technical outlay for the heat-ing of drum dryers is relatively low. Modern burners have only relatively small fans for the combustion air. In most cases, it is not necessary to use fans to blow the drying air into the dryer or to install costly piping.
Granulation rate reach to 99% and yield rate is 98% without return product. It does not affect the granulation of raw materials with high crude fiber content. It has low moisture while granulating. When you dry organic fertilizer pellets, it just needs proper temperature for drying. the fertilizer granulation process keeps beneficial ...
The temperature in the drum is moderated by the evaporation of water from spray nozzles located inside the drum. Low Capex and Opex for high capacity sulphur forming. IPCO sulphur drum granulators are supplied prefabricated for fast delivery and rapid installation.
Nov 09, 2010· Alternatively, temperature may be used to monitor fluidized bed drying. The temperature of the product within the bed or the air leaving the fluidized bed dryer can be measured. During drying, the air and product temperatures are cooled as a result of the evaporation of water from the granules.
The granules than discharged to the dryer drum for drying by heating up to 600 deg.temperature. The final moisture content in the granules is about 6%. The material comes from dryer are cooled in cooler drum. After cooling of the granules, granules are sending to the vibrating screened for desired mesh.
granule curtain density, temperature of slurry and seed to be coated, granule density, air temperature inside the granulator-dryer, etc. Some of these parameters can be observed and controlled, some of them are not. The design and control scheme of the drum granulator-dryer normally force layered growth or
Dry Granulation:The Definitive Guide Do you want to be an expert in dry granulation process? If yes, then this is the BEST guide for you. Reason: I am going to take you through an in-depth analysis of critical aspects about dry granulation techniques. From the definition, basic principles, advantages, disadvantages, machines, practical applications to factors […]
Fertilizer dryer is a key equipment in fertilizer production line. It can dry pelleted organic or compound fertilizer well. Tongda drying machine utilizes aeration-drying technology for drying materials. Our rotary drum dryer takes advantages of hot blast furnace for supplying air. The hot air will dry the materials inside the cylinder.
Rotary drum granulation technology. Rotary drum granulator is a key equipment in fertilizer industries to produce both high and low-density compound fertilizer. The theory of rotary drum granulation process is that all raw materials roll and solidify in the drum so that the raw materials could be fully react with each other. By means of rotary ...

You can easily process them with dry granulation, but it will be hard to do this by other means. Normally, you should pair a rotary drum dryer with granulators to dry out the pellet products. It means you need to heat the products up. Some temperature sensitive materials might change their properties during this process.
After the fertilizer granules are processed by drum granulator, they must be dried to strengthen the granules, so that the water content of the granules can meet the requirements of product water content. We improved the drum dryer to improve the quality of particle drying.
The fluidized bed spray granulation is a method for making free-flowing granulate from liquids. It can be used in different applications in various industries, since the product properties can be varied in many ways by setting process technical parameters and configurations. The granules are suitable for making tablets and, because of their ...
The compressive strength of new type granulator is higher than disc granulator and rotary drum granulator. Size of particles is adjustable in accordance with customers' requirements. This fertilizer granulator is most suitable for direct-granulation after organics fermentation, saving drying process, and greatly reducing the production cost.
The drum drying process. The drum body of the drum dryer is heated on the inside by steam. A special composition of cast iron gives the drier a combination of favourable properties: accurate shape retention even at high steam pressure and temperature, and excellent "scraping properties" for the scraping knife.
