Pig manure organic fertilizer granulator is a kind of equipment that processes pig manure and other organic materials into granular organic fertilizer, and its working principle is to process the treated pig manure materials into granular organic fertilizer with consistent specifications through extrusion, granulation and other technologies, which is convenient for transportation and application.
I. Product Overview
Pig manure organic fertilizer granulator is a kind of efficient molding equipment specially for the resource utilization of livestock and poultry manure in pig farms, which can process organic raw materials such as pig manure after decomposition into regular and uniform organic fertilizer granule products. The machine not only solves the problem of waste pollution in the aquaculture industry, but also realizes the economic transformation of breeding by-products, forming a dead cycle mode of “planting and breeding cycle” and “waste to fertilizer”, which is one of the indispensable core equipment of modern circular agriculture and environmentally friendly fertilizer enterprises.
Pig manure is rich in nitrogen, phosphorus, potassium and organic matter, especially after full fermentation, its nutrients are stable and the absorption rate is moderate, which is the best raw material for making organic fertilizer. Pelletizing can not only increase the commodity value of fertilizer, but also extend the nutrient release cycle, facilitate storage and mechanical fertilization, and further expand market application scenarios.
II. The working principle
Generally speaking, the main components of pig manure organic fertilizer pelletizing machine include feeding system, extrusion system, pellet forming system and control system, etc. Among them, the feeding system is mainly responsible for feeding raw materials such as pig manure into the extrusion system, the extrusion system extrudes the raw materials into solid particles through the extrusion gear, the particle forming system is responsible for shaping the extruded particles, and the control system is responsible for monitoring and controlling the operation of the equipment.
According to different models, pig manure organic fertilizer granulator has a variety of structural types such as flat die extrusion type, vertical disturbing and mixing type, new organic granulator, disc granulator and roller extrusion granulator.
The following is an introduction to the process principle:
Fermentation and pretreatment: After the pig manure is composted at high temperature, the moisture is controlled at about 30%, and it has been decomposed and odorless, and pretreated by crushing and stirring.
Material feeding: The pig manure with suitable moisture and ratio enters the granulator by the feeding device, and is evenly mixed with the added conditioning substances (such as humic acid, mineral source powder, carbon powder, etc.).
Granulation molding: through die roll extrusion, rotary disturbing or centrifugal spun rounding, etc., the powdery materials are agglomerated into spherical or columnar particles. The formation process is purely mechanical-physical and does not require high temperature and pressure.
Particle discharge and screening: After the preliminary formed particles are output through the discharge port, they are graded through the trommel screen, and the oversized and too small particles are returned for re-granulation.
Post-processing section: Qualified particles can be cooled, coated, dried, dusted and automatically metered and packaged according to the needs to form a complete automatic process.
According to the capacity demand and process characteristics, it can be configured with stand-alone operation or joint production line operation, and flexible expansion and high automation have become its significant advantages.
III. Product application
Pig manure organic fertilizer granulator has a wide range of applications, covering the following areas:
Large-scale pig farm manure resource utilization: realize the conversion of pig manure into organic fertilizer on the spot, reduce the pressure of manure discharge, and meet environmental protection supervision standards.
Raw material pretreatment and main granulation equipment of organic fertilizer plant: pig manure and straw, fungus residue, biogas residue and other mixed granulation to improve the fertilizer efficiency structure.
Modern Ecological Agricultural Park: Convert manure into local fertilizer for self-use, and create a “zero pollution” and “zero emission” agricultural demonstration base.
Comprehensive agricultural enterprises and order agricultural cooperatives: provide customized products (such as pig manure granular fertilizer, special formula fertilizer, coated controlled-release fertilizer, etc.) to meet market demand sales.
The granulated pig manure fertilizer has the characteristics of good stability, low odor and high adaptability of mechanical application, and is widely used in grain fields, orchards, tea gardens, greenhouse vegetables and other areas, and is increasingly favored in domestic and foreign markets.
IV. Product features
1. Targeted design, effective and stable treatment of pig manure
Combined with the characteristics of high moisture, high fiber and adhesive properties in pig manure, a strong extrusion structure and self-cleaning mold system are selected to prevent blockage and agglomeration, and run smoothly.
2. High granulation rate and good quality of finished products
The particle forming rate can reach more than 90%, and the shape is round, dense and not easy to break. The particle size size is 3~8mm adjustable, which is suitable for a variety of fertilizer spreading machines.
3. Low energy consumption, simple structure and easy maintenance
The motor has moderate power, modular design of the overall structure, easy installation and debugging, easy to replace accessories, and can be operated and maintained by a single person.
4. Support compound and customized production
Amino acids, humic acid, diatomaceous earth, plant extracts and other formulas can be added to make functional fertilizers to meet the fertilization requirements of different crops.
5. One machine is multi-purpose, suitable for a variety of organic raw materials
In addition to pig manure, it can process chicken manure, cow manure, duck manure, sheep manure, kitchen waste, distiller’s grains and other materials, with multiple uses and high return on investment.
6. There is a lot of room for intelligent upgrades
It supports the configuration of PLC intelligent control panel, material proportioning automation module, moisture monitoring unit, remote data platform and other systems to realize the construction of digital factory.
7. Flexible coverage of multi-model production capacity
Provide various models with a daily output of 3 tons ~ 50 tons to meet the various needs of family farms and industrial fertilizer enterprises.
If you plan to build a pig manure organic fertilizer production line, we can further provide you with your expected production capacity, raw material structure and site area, and I can assist you in configuring a complete equipment list, technical solutions and capital budget suggestions.
