The rotary drier is used for compost pellets drying. There are moisture requirements for organic materials composition and pelleting. After compost granulation, granular fertilizer need drying for stocking and packaging. In ShunXin fertilizer machinery, there are common used fertilizer dries, rotary drier, and scraper type fluidize dryer for your compost pellets drying applications.
The rotary drying facility is mainly used for powdery, granular or sticky composts drying. It features rotary drum structure and gear transmission system. ShunXin is a rotary dryer specialties Inc.
What is the rotary dryer accessories design?
There are main three components consists of the entire rotary drum dryer. There is rotary dryer vent cleaner installed on the rotary drier. This design enables winds force into the machines drums. The drum design of the rotary drier enables the machine dry materials in a large capacity. Meanwhile it also let the fertilizer dry thoroughly with this rotary structure. The transmission gear can let the drier work efficiently. All the drier accessories are designed with leading material drying technologies. You can process your moisture granular composts safely and efficiently.
How does the rotary drier operating at atmospheric pressure?
The dry air flows into the rotary drum through the furnace room. The burnt soot and the water vapor generated by the drying are discharged by the smoking dust removing device through the exhaust pipe. The gas temperature of the inlet cylinder is tested by a thermocouple on the feed chamber, and the furnace temperature is adjusted by controlling the amount of coal burned and the flow of natural wind. The material enters the rotating cylinder from the inlet, and the material is continuously flipped and thrown away, so that the material maintains good contact with the dry hot gas, and the heat exchange is achieved, so that the material can be dried. The cylinder of the dryer is supported on the retaining wheel device and the roller device by the front and rear rolling rings, and the retaining wheel on the retaining wheel device prevents the cylinder from moving forward and backward. The transmission is driven by the motor through the cycloid reducer to drive the simplified upper gear. Sealing device is arranged at both ends of the cylinder to prevent cold air from entering the cylinder and the combustion chamber into the cylinder of the flue gas, dust overflow, the cylinder, the feeding chamber and the discharge chamber. The collected materials can be cleaned.

Why should you buy a fertilizer dryer?
Humidity is also one of the key issues for fertilizer plants to manage. Excessive humidity leads to equipment corrosion and affects the machines service life; in the production workshop, electrical appliances, over humidity fertilizers often cause electrical discharge or burnout; humid air is conductive, which may cause short circuit of electrical appliances and pose a threat to operators’ life and property.
Humidity is one of the key problems that restrict the production of water-soluble fertilizer. Because in the process of water-soluble fertilizer production, some materials contain crystal water, which is easy to absorb moisture. The contact area between material and air in the production process is large, due to the high humidity in the air. It will cause agglomeration of water soluble fertilizer. Therefore, solving the problem of water-soluble fertilizer absorption is the current urgent task of enterprises. Facilitating a drier for your fertilizer plants is quite necessary.
What’s is the function of the compost drier?
Prevent chemical reactions between raw materials and affect fertilizer efficiency
The fertilizer itself is formulated from various salt crystals and a small amount of auxiliary materials. In the presence of moisture, a chemical reaction can take place between the ingredients of the ingredients to form a double salt and a solid tour.
These reactions can even be extended to the finished product after packaging. Therefore, in the production of fertilizers, it is necessary to fully understand the compatibility between the raw materials, and if necessary, in the material pretreatment period, such as pretreatment of the superphosphate, to control the reaction of the release of crystal water inside the compound fertilizer.
Prevent the agglomeration formation
Agglomeration is a property in which a substance changes from a loose state to a mass or a whole. This transformation, whether it is a finished substance or an amorphous substance, may occur. The agglomeration of fertilizer has a great relationship with humidity. When the surface of the material absorbs water, it will form a saturated guest liquid. After that, due to evaporation of water or absorption by other dry materials, the dissolved components will precipitate and precipitate crystals due to the surface of the material. The process of dissolution and recrystallization is continuously performed, forming a crystal bridge leading to agglomeration.
Prevent organic material sticking
When the raw material absorbs water, some materials will be sticky, which will result in poor fluidity of the material. It is easy to hang on the side wall of the production equipment during the production process of the fertilizer, and the thicker and thicker, the flow layer and the blanking passage become smaller, resulting in poor feeding, affecting the stability of the ingredients.
ShunXin compost rotary drier for sale can dry organic fertilizers, compound fertilizers, and there are also some types of driers can dry organic materials, such as sawdust, sludge, any configurations, the company can tailor to you.
