The dry rolling technology is used in the
double roller granulator to compress the powder materials with water content ≤ 15% into pieces or blocks, and then through the crushing and screening process, the pieces and blocks of materials become the granular materials that meet the use requirements. The double roller granulator mainly relies on the external pressure mode, so that the material is forced to pass through the gap between two relative rotating rollers and compressed into pieces. During the rolling process, the actual density of the material can be increased by 1.5-3 times, so as to achieve certain particle strength requirements.
As the key equipment of compound fertilizer and organic fertilizer granulation, the double roller granulator has the advantages of advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, matching with the corresponding equipment, forming a small production line, which can form a certain capacity of continuous and mechanized production. The double roller granulator does not need to be dried and produced at normal temperature. The product is rolled once, and the product quality is first-class. This
fertilizer granulator can also be used to produce high, medium and low concentration special compound fertilizer for various crops. The double roller granulator is an updated product of energy conservation and consumption reduction in the compound fertilizer industry at present.
Installation method of the double roller granulator
1. Axial alignment: it has been adjusted during installation. Generally, it is unlikely to be adjusted properly. When adjustment is needed, tighten or loosen the gland on both sides of the passive bearing seat, so as to push the displacement of the eccentric sleeve corresponding to the active shaft roller.
2. Circumferential alignment: the steps of circumferential alignment are as follows: loosen the 6 screws of the passive gear and the adjusting sleeve, so that the adjustment and the passive gear are slightly separated. Since a ball socket adjustment amount has been tested in the design, and two adjusting bolts are equipped, the wrong position can be adjusted no matter how much the dislocation is.
