Roller dry granulation Machine Working principle:
A variety of dry powder materials from the top of the equipment, by degassing, spiral preloading into the roll, the roller under the effect of the crushing force of the material produced plastic deformation and compressed into the shape. The flake material is then broken, the whole grain, sieving and so on process, obtains the pellet product. The size of the extrusion pressure can be adjusted by the pressure of the hydraulic cylinder according to the need of granulation operation.
Drum Granulator principle:
Into the machine into the steam, gas ammonia or add phosphoric acid, nitric acid, sulfuric acid or nitrogen solution, phosphate ammonia slurry, heavy calcium slurry, in the tubular reactor to complete the chemical reaction of the complex fertilizer granulation process; or add a small amount of water to the compound fertilizer cold granulation process. The material that needs to be granular is rotated and rotated in the cylinder by rotating the cylinder body in a certain humidity, the temperature of the material glued to the ball, in the movement of smaller particles gradually formed a certain size of particles, complete granulation process. Dry roller Pressure granulator working principle: Dry powder materials from the top of the equipment to join, to get granular products.
