Roller granulator can be used for compound fertilizer granulation
The roll extrusion granulator is a granulation device. It is produced by a dry-free normal temperature process and molded at one time. The equipment has low investment, quick effect and good economic benefits. The roll extrusion granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and is matched with corresponding equipment to form a small production line, which can form a continuous production capacity. , mechanized production. The squeezing granulator adopts eugenic formula, which does not need to be dried, and is produced at room temperature. The product is rolled and formed at one time, so that the product quality meets the requirements of compound fertilizer technical specifications, and it is a special compound for the production of high, medium and low concentrations of various crops. A new generation of energy-saving and consumption-reducing products in the compound fertilizer and compound fertilizer industry.
Main use of the roll granulator
1, industrial recycling dust materials: such as iron, dust, lead, zinc, aluminum dust, converter dust, dust, grinding and other dust. The material is forced compression molding by mechanical pressure, without adding any wetting agent, the purity of the product is guaranteed.
2, the roller granulation process is short, low energy consumption, large output. Direct granulation of dry powder, no need for subsequent drying process, more conducive to the connection and transformation of existing production processes. The high particle strength and the increase in bulk specific gravity are more significant than other granulation methods.
3, especially suitable for increasing the proportion of product accumulation. The operation is large and flexible, and the range of the pressing force can be adjusted by the hydraulic pressure.
Working principle of roller granulator
The roller granulator is an extrusion sliding model, and its working principle is: the belt and the pulley are driven by the motor, transmitted to the driving shaft through the speed reducer, and synchronized by the split gear and the passive shaft to work in opposite directions. The material is added from the feeding hopper, extruded by a pair of rolls, demolded and pelletized, and passed through a pair of chains, transferred to a crushing sieve working chamber of a roll granulator, sieved and separated into finished particles (balls), and then returned. Mix with new material and granulate. As the motor continues to rotate and the material continues to enter, mass production can be achieved.
