3 Ton Per Hour Disc Fertilizer Granulation Production Line

Overview of 3 Ton Per Hour Disc Fertilizer Granulation Production Line

The 3 ton per hour disc fertilizer granulation production line is a mature, cost-effective small-scale fertilizer manufacturing system, specially designed for medium and small fertilizer processing plants, agricultural cooperatives, and breeding enterprises. Centered on a disc granulator, this complete production line realizes continuous, automated processing from raw material crushing, mixing, granulation to finished product screening and packaging. With a stable hourly output of 3 tons of qualified fertilizer granules, it perfectly meets the production demand of daily 60-80 tons of granular fertilizer, covering organic fertilizer, compound fertilizer, and bio-organic fertilizer production scenarios.

Compared with large-scale fertilizer production equipment, the 3t/h disc fertilizer granulation line features compact structure, low investment, easy operation and flexible site layout. It has become the most popular small granulation production line in the agricultural fertilizer industry, solving the problems of low efficiency, uneven particle size and high production cost of traditional manual fertilizer processing.

Working Principle of Disc Fertilizer Granulation Production Line

The core granulation principle of the 3 ton per hour disc fertilizer granulation production line is physical rolling agglomeration. Relying on the centrifugal force, gravity and friction generated by the rotating inclined disc, powdery fertilizer materials complete the whole process of nucleation, rolling, rubbing and compaction to form uniform spherical granules, without high-temperature chemical reaction, which fully retains the active ingredients of fertilizer raw materials.

During operation, the pre-crushed and evenly mixed fertilizer raw materials are quantitatively sent to the disc granulator by the feeding system. The atomized water spray device sprays an appropriate amount of binder or water according to material characteristics. With the continuous rotation of the disc, the materials roll and collide repeatedly, gradually grow into round and solid particles, and are automatically discharged after reaching the standard particle size. The whole granulation process is stable and controllable, with a granulation forming rate of more than 85%, effectively reducing raw material waste.

Complete Process Flow of 3T/H Disc Fertilizer Granulation Line

The 3 ton per hour disc fertilizer granulation production line adopts a standardized and streamlined production process, with complete supporting equipment and smooth connection of each link. The whole production process is fully automated, reducing manual intervention and improving production efficiency. The detailed process flow is as follows:

1. Raw Material Preprocessing

Raw materials such as chicken manure, cow manure, crop straw, sludge and fertilizer raw materials are crushed by a professional crusher to control the fineness of powdery materials, and then screened to remove impurities and large-particle materials to ensure uniform raw material particle size, laying a foundation for subsequent high-quality granulation.

2. Material Mixing and Proportioning

According to the fertilizer formula requirements, various raw materials and auxiliary materials are accurately proportioned and fully stirred by a double-shaft mixer to realize uniform mixing of materials and stable moisture content, avoiding uneven nutrient distribution of finished fertilizer.

3. Disc Granulation Forming

This is the core link of the production line. The mixed materials are evenly fed into the disc granulator. By adjusting the disc inclination (30°-60° adjustable) and rotating speed (10-30r/min), the materials form spherical granules with uniform size and firm texture. The particle size can be flexibly adjusted between 2-6mm to meet different fertilizer standards.

4. Drying and Cooling

The newly formed fertilizer granules have high moisture content and are easy to adhere. They are sent to the dryer for low-temperature drying to reduce material moisture, and then cooled by a cooling machine to stabilize the particle hardness and prevent granule deterioration and mildew.

5. Screening and Finishing

The cooled fertilizer granules are screened by a rotary screening machine. Qualified granular fertilizers enter the next process, while unqualified large particles and fine powder are returned to the mixing system for reprocessing to ensure 100% qualified finished products.

6. Automatic Packaging

The qualified finished fertilizer granules are quantitatively weighed and packaged by an automatic packaging machine, realizing finished product molding and storage, which is convenient for transportation, sales and field application.

Core Advantages of 3 Ton Per Hour Disc Fertilizer Granulation Production Line

1. Stable Output and High Granulation Efficiency

Designed for a standard hourly output of 3 tons, this disc fertilizer granulation production line operates continuously and stably for a long time with no blockage or shutdown failure. The optimized disc structure eliminates material dead corners, ensuring uniform material rolling and stable granulation efficiency. The finished particle roundness is good and the size is uniform, fully meeting commercial fertilizer production standards.

2. Wide Adaptability of Raw Materials

The production line is compatible with various fertilizer raw materials, including organic raw materials such as livestock and poultry manure, decomposed straw, mushroom residue and sludge, as well as inorganic raw materials such as nitrogen, phosphorus and potassium. It can produce pure organic fertilizer, compound fertilizer, bio-fertilizer and other products, with flexible production and diverse product types.

3. Low Investment and Low Operating Cost

Different from large-scale granulation equipment with high price and large floor area, the 3t/h disc fertilizer granulation line has a compact overall structure, small floor area and low equipment investment cost. The whole line is driven by low-power energy-saving motors, with low energy consumption and simple daily maintenance. It has low requirements for factory buildings and workers' operation technology, which is very suitable for small and medium-sized enterprises to start businesses and expand production.

4. Simple Operation and High Automation

The production line adopts integrated automatic control, with centralized operation of feeding, mixing, granulation, drying and packaging links. One or two workers can complete the whole production operation. The disc granulator has adjustable parameters, simple and intuitive operation, stable equipment performance and low failure rate, greatly reducing labor costs and production management difficulty.

5. Good Finished Product Quality and High Market Value

The fertilizer granules produced by the 3 ton per hour disc fertilizer granulation production line have firm texture, uniform particle size, moderate hardness and not easy to break and agglomerate. The granular fertilizer is convenient for mechanical fertilization, slow fertilizer release and long fertilizer efficiency, which is more popular in the agricultural market and has higher sales value than traditional powdery fertilizer.
