The organic fertilizer npk fertilizer production line is mainly to ferment and decompose the animal manure organic wastes such as cow manure, sheep manure, pig manure, chicken manure, sludge, rice straw, corn straw, etc, and add nitrogen, phosphorus and potassium (total nutrient content). Less than 15% can produce organic and inorganic fertilizer) ingredients and mixing, the fully mixed material is uniformly and continuously fed into the granulator by the belt conveyor for granulation.
The equipment required for the granular organic fertilizer npk manufacturing process is fermentation turner, horizontal mixer, semi-wet grinder, organic fertilizer granulator, organic fertilizer screening equipment, automatic packaging machine, etc. The investment of a small production line is about 200,000.
The most important thing in the production of granular organic fertilizer is the organic fertilizer granulator. The following introduces the double roller granulator, the rotary drum granulator and the disc granulator.
1. The double roller granulator uses the motor as the power to connect the belt, which drives the two counter-roll molds to rotate oppositely. The semi-circular grooves of the same size are distributed on the mold, and the mold 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.
2. The organic fertilizer rotary drum granulator process does not have the phenomenon of large particles and sticky materials that limit the four-disk creation, which is conducive to the classification of dry and wet particles, and the relative granulation ratio is relatively low, generally 40% -60%. Therefore, the reaction rate is high, but the requirements for the mixing and degree of material mixing in the mixing process are relatively low.
3. The disc granulator is powered by a motor to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates to the top, it rolls down by itself, and rolls into particles like a snowball. Suitable for non-sticky powdery materials.
