The main process of powdery organic fertilizer machine is as follows: the organic fertilizer raw materials, livestock manure or domestic garbage, sludge, wine tank, biogas residue, etc., are fermented and decomposed, crushed, mixed and packaged. The basic process configuration of organic fertilizer equipment is dehydration, drying, fermentation, crushing, mixing, and packaging. This completes the processing of powdered organic fertilizer. Compared with the simple process of powdered fertilizer, granular organic fertilizer requires further processing. The basic process configuration of granular organic fertilizer equipment is dehydration, drying, fermentation, crushing, stirring, granulation, cooling, and packaging. It is necessary to configure an organic fertilizer granulator, organic fertilizer dryer, organic fertilizer coating machine, and after granulation. After being mechanically cooled, it can be packaged, stored or sold.
Process system equipment of organic fertilizer production line process flow
1. Fermentation system: The fermentation system of the process flow of the organic fertilizer equipment is composed of a feed conveyor, a biological deodorizer, a mixing mixer, a proprietary lift-up turning machine and an electrical automatic control system, etc.
2. Drying system: The main equipment includes belt conveyor, drum dryer, cooler, induced draft fan, hot blast stove, etc.
3. Deodorization and dust removal system: settling room, dust removal room, etc.
4. Crushing system: including a new type of semi-wet material crusher, LP chain crusher or cage crusher, etc.
5. The batching system includes equipment including electronic batching system, disc feeder, vibrating screen, 6-8 kinds of raw materials can be configured at a time, etc.
6. The mixing system consists of optional horizontal mixer or pan mixer, vibrating screen, mobile belt conveyor, etc.
7. The organic fertilizer granulation system requires granulator equipment. The optional granulator equipment are: organic fertilizer compound fertilizer combination granulator, roller press granulator, disc granulator, organic fertilizer Dedicated granulator, NPK and organic fertilizer granulator, etc.
8. Drying system: The organic fertilizer drying system consists of a drum dryer and a cooler
9. Screening and coating system: It is mainly completed by a drum screening machine, which can be equipped with a first-level screening machine and a second-level screening machine to make the finished product rate higher and the particles better. After screening, the coating can be used to maintain fertility. Radiate
10. The finished product packaging system generally includes electronic quantitative packaging scales, silos, automatic sewing machines, etc., so that full-automatic non-intermittent production of organic fertilizer equipment can be realized. The conveying system mostly uses belt conveyors and screw conveyors.
The disc granulator can process many raw materials, such as cow manure, chicken manure, sheep manure, pig manure, duck manure, peat soil, silica fume, sludge, drug residue, mushroom residue, etc.
Disc fertilizer production process can meet most fertilizer processing requirements.Disc fertilizer manufacturing processThe disc granulator is composed of an angled tray and a supporting structure.
There are many types of disc granulator, with diameters of 0.8m, 1m, 1.5m, 1.8m, 2m, 2.8m, 3m, etc.The inclination angle and the rotating speed of the disc are adjustable.
The material mixed by the mixer is sent to the top of the disc by the belt conveyor, and continuously enters into the disc quantitatively.
The material in the disc is bonded by a spray of adhesive and wrapped into granules.
As the disc rolls, the particles grow up gradually.Due to the remarkable grading capacity of the disc granulation machine, large particles float on top and are continuously discharged from the bottom of the disc.
Fertilizer production line generally uses the following methods to granulate:1.
Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing.
The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller granulator.2.
Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate.
Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles.
This method is used in disc granulator and rotary drum granulator.3.
