The complete set of npk manufacturing process can usually be divided into: raw material batching, raw material mixing, raw material granulation (drum granulator, counter-roll granulator), particle drying, particle cooling, particle classification, finished product coating, Final product packaging.
NPK fertilizer production line (NPK) is our fertilizer production equipment product with stable operation, high quality and easy maintenance and repair. High ball formation rate, less external circulation materials, low comprehensive energy consumption, no pollution, and strong adaptability.
At present, the compound fertilizer mixing method of the roller extrusion granulator has developed rapidly both in foreign countries and in China. The roller extrusion granulator strictly controls the particle size, so how does the roller granulator work?
The double roller granulator uses the motor as the power to connect the belt, and drives the two counter-roll dies to rotate toward each other. The semi-circular grooves of the same size are distributed on the die, and the die rotates to the contact point to form a circle. The resulting particle size is determined by the abrasive tool selected and is formed in one pass. It is suitable for organic fertilizer, compound fertilizer, feed, chemical industry and other fields.
The roller extrusion organic fertilizer granulator is an improved product that absorbs the new technology of the international granulator. The machine is equipped with a feeding system that is connected with a pre-continuous feeder with a machine touch device and a forced feeding screw feeding hopper, which ensures the continuity, adequacy and uniformity of the feeding, which is an important step. The paired rolls are engraved with evenly distributed arc grooves, which is beneficial for the material to bite into the rolls, causing the arc groove to seal the cavity (belt) during operation, and also beneficial for the compaction of the material, reducing the forming pressure of the mechanism and the load of the main engine, and improving the rolling process. sheet manufacturing rate.
