1. Raw Material Pretreatment Equipment
● Pulverizer: Crushes bulk materials into powder or small granules that meet granulation requirements.
● Mixer: Evenly blends various raw materials (such as base materials and additives) to ensure consistent granule composition after granulation.
2. Core Granulation Equipment
● Agitator Granulator: This is a key piece of equipment in the production line, consisting of a machine body, agitator rotor, screen, and transmission system. The high-speed rotation of the agitator teeth shears, squeezes, and kneads the material, forcing it through the screen to form cylindrical granules.
3. Post-Processing Equipment
● Cooler: Cools hot granules freshly produced to prevent them from clumping or deteriorating.
● Screening Machine: Screens granules that meet the required particle size, returning unqualified granules for re-granulation.
● Packaging Machine: Automatically measures and packages qualified granules for easy storage and transportation.
Application Scenarios
1. Agricultural Planting: Used for soil improvement of field crops, quality improvement of cash crops, and seedling cultivation and maintenance in greenhouse agriculture.
2. Aquaculture Support: Farms process manure and wastewater to produce organic fertilizer, establishing a "farming-manure-planting" cycle.
3. Solid Waste Treatment: Converting municipal sludge, garden waste, and food waste into organic fertilizer, reducing solid waste and maximizing resource utilization.
4. Organic Fertilizer Processing: Manufacturers produce organic-inorganic compound fertilizers and bio-organic fertilizers to meet customized needs.
The core of the agitator granulation line utilizes the high-speed mixing and shearing action of the agitator granulator to granulate materials:
1. Raw Material Pretreatment: Crush the raw materials to 20-80 mesh, mix them evenly according to the recipe, and adjust the moisture content to 25%-40%.
2. Agitator Granulation: Upon entering the granulator, the high-speed agitator teeth impact and shear the raw materials, agglomerating them into 2-6mm granules.
3. Drying: Wet granules are dried with hot air to reduce the moisture content to below 10%.
4. Cooling: Cool the granules to near room temperature to prevent secondary moisture absorption.
5. Screening: Separate qualified granules, re-crush large granules, and re-mix fine powder for reuse.
6. Coating (Optional): Spray coating agents to enhance performance.
7. Metering and Packaging: Weigh and bag the granules according to specifications.
Advantages of the Agitator Tooth Granulating Line:
1. High Efficiency and Adaptability:
It directly processes wet materials with a moisture content of 25%-40% (such as manure and sludge), with a single unit producing 1-15 tons per hour, suitable for various production scales.
2. High-Quality Granules:
The finished product is nearly spherical with adjustable particle size, strong compressive strength, high porosity, and uniform nutrient distribution.
3. Low Energy Consumption and Cost-Effectiveness:
No pre-drying is required, resulting in low energy consumption. Replacement costs for wearing parts are low, and operating and maintenance expenses are minimal.
4. Environmental Compliance:
It can be equipped with deodorization and dust collection systems to reduce secondary pollution, complying with agricultural waste resource utilization policies.
Scale Type | Small production line | Medium production line | Large production line |
Daily processing capacity | 2-8 tons | 10-40 tons | 40-60 tons |
degree of automation | There are many manual operations, such as manual loading and manual adjustment of equipment operating parameters, and few automated control links. | Some links are automated, such as automatically adjusting the temperature, humidity, and feed volume of materials through sensors and control systems, reducing manual intervention | Highly automated, using PLC control system to automatically adjust equipment operating parameters according to production conditions |

What raw materials can the production line process? What is the required moisture content?
The organic raw materials it can process cover a wide range of sectors, including agriculture, animal husbandry, and industry. These include livestock manure from pigs, cattle, sheep, and chickens, corn/wheat straw, mushroom residue from edible fungus cultivation, dewatered sludge from municipal sewage treatment, and distiller's grains, bean dregs, and fruit residue from food processing. The core material is suitable for wet materials with a moisture content of 25%-40%. Unlike extrusion granulators, there is no need to pre-dry the material to below 15%, significantly reducing pre-processing steps and energy consumption.
What is the output of a single production line? What scale of production can it meet?
The hourly output of a single core device ranges from 1 to 15 tons. The model can be selected based on user needs: Devices with an hourly output of 1 to 3 tons are suitable for home-based workshops or small farms, meeting the fertilizer needs of farmland within 500 mu (approximately 16 acres). Devices with an hourly output of 4 to 7 tons are suitable for medium-sized organic fertilizer plants, serving the regional planting market. Large-scale production lines with an hourly output of 8 to 15 tons can support large-scale organic fertilizer processing companies, enabling nationwide distribution and sales.
Can the particle size of the finished granules be adjusted? What are their shape and strength?
The particle size of the finished granules can be flexibly adjusted by replacing the screen within the device. Fine granules are suitable for delicate cultivation applications such as vegetable seedlings and potted flowers; medium granules are suitable for cash crops such as fruit trees and tea plantations; and coarse granules are more suitable for field crops such as wheat and corn. The granules are nearly spherical and have good flowability, facilitating subsequent packaging, transportation, and field spreading. With a compressive strength of 1.5-2.5 MPa, they resist breakage during stacking and transportation, with a breakage rate typically below 5%. The granules retain uniform pores, allowing them to quickly absorb water and allow air to pass through the soil, promoting the slow release of nutrients and extending the fertilizer's effectiveness.
Will odor or dust be generated during the production process? How is this handled?
The accompanying deodorization system (spraying + biofilter) and dust collector (pulse bag type) effectively control odor and dust emissions, complying with environmental standards and preventing secondary pollution.
Can the production line produce different types of organic fertilizers, such as bio-organic fertilizers and compound fertilizers?
Yes; by adjusting the raw material formula, we can produce bio-organic fertilizers and organic-inorganic compound fertilizers to meet different market needs.
