The production process of organic fertilizer equipment is mainly that the previously fermented organic fertilizer raw materials are crushed, screened, and then measured, batched and mixed (or further dried to produce powdered organic fertilizer) with binder and other ingredients according to the ratio requirements in the automatic batching mixing system. The fully mixed material is fed into the granulator evenly and continuously by the belt conveyor.
Common organic fertilizer granulation processes are: drum granulator, disc granulator, and organic fertilizer granulation mainly uses roll press granulator, drum granulator, disc granulator, etc
The roll press granulator will extrude the powder forming, crushing, finished product screening and other processes into one, compact structure, convenient operation. The powder from the hopper is continuously and evenly added to the top of the two rolls. Under the action of continuous rotation of the extrusion roll, the powder is bitten into the two rolls and extruded into the board, and then falls off under the centrifugal action and the board’s own gravity. The shaping wheel with teeth and claws is separated into particles and then enters the dividing screen. The powder under the screen is sent back to the material, the grain on the screen is rolled by the roller, the acute Angle of the particle is ground, and the discharge port on the screen bucket is discharged into the packaging.
Roller extrusion granulator has the following advantages : 1. Cycle operation, continuous production and high output of finished products; 2. The material is forcibly compressed and formed by mechanical pressure without any additives, thus ensuring the purity of the product. 3. Particle strength can be adjusted, and finished product strength can be controlled by adjusting the pressure of the roller; 4.Extrusion granulator is suitable for a variety of raw materials , particle strength can be adjusted according to different materials. 5. Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.
