Double roller extrusion granulator - the key equipment of compound fertilizer and organic fertilizer

Update time : 2021-11-19 Publisher:Tongda

For double roller extrusion granulator, the shape and size of the ball and socket on the roller skin can be determined by the needs of users, and the roller extrusion granulator has a wide range of choices. The ball pressure shape is pillow shape, semicircular grain shape, bar shape, pill pill shape, walnut shape, flat ball and square bar shape.  At present, the flat ball shape is used.  
The double roller extrusion granulator is produced by no drying process at room temperature, forming once.  The equipment has low investment, quick effect and good economic benefit.  Complete set of equipment layout compact, scientific and reasonable, advanced technology.  Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation, convenient maintenance.  Wide adaptability of raw materials, suitable for compound fertilizer, medicine, chemical, feed and other raw materials granulation, high pelletizing rate.  
To double roll extrusion pelleting machine is the key to the compound fertilizer granulation equipment, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and the corresponding equipment facilities, and small production line, can form a certain capacity of continuous, mechanized production, no dry, normal production, a rolling forming products, make the quality of the products conform to the requirements of the technical indicators are mixed fertilizer,  It is used for the production of various crops of high, medium and low concentration special compound fertilizer and compound fertilizer industry energy saving and consumption replacement products.

Capsule filling particles, pigment, detergent, catalyst, strontium carbonate, chemical fertilizer, white carbon black, inorganic salts, chloride, cyanuric acid, pesticides, oxides, and industrial recovery dust materials: such as cast iron factory dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding dust and so on.  Material by mechanical pressure forced compression molding, without adding any wetting agent, product purity is guaranteed.  
Extrusion granulation production process is short, low energy consumption, large output.  Dry powder directly granulation, no subsequent drying process, more conducive to the connection and transformation of the existing production process.  The particle strength is high and the increase of bulk density is more significant than other granulation methods.  It is especially suitable for increasing the proportion of products.  Operation flexibility, wide range of adaptation, the size of extrusion pressure can be adjusted by liquid pressure.
