New pet of pig farm: feed granulator improves feed utilization and reduces costs

Written by fertilizer production line on . Leave a comment

As an important part of animal husbandry, pig industry faces the problems of high feed cost and low feed conversion rate in modern large-scale breeding. In order to improve the economic benefits of pig farms, the new feed granulation technology came into being and became the new pet of pig farms. Through the use of feed granulator, this technology not only improves the utilization of feed, but also effectively reduces the cost of farming.
 

1. Efficient transformation of Fertilizer Granulating Production Line

 
The Fertilizer Granulating Production Line uses a series of processes to produce granular feed from various raw materials. Such production lines usually include crushing, mixing, granulation, drying and packaging. In the pig farm, the pellet feed processed by this production line has the advantages of balanced nutrition, easy digestion, reducing waste and so on, thus improving the utilization rate of feed.
 

2. the recycling of Organic Fertilizer Production Line

 
In pig farms, manure and waste water are common wastes. Through the Organic Fertilizer Production Line, this waste can be converted into organic fertilizer. This organic fertilizer can not only be used in pig farms to increase crop yields, but also can be sold as a commodity, bringing additional economic benefits to pig farms.

3. Precise granulation of Flat-Die Pellet Machine

 
The Flat-Die Pellet Machine is the key equipment in the feed pelletizing production line, which can precisely control the grain size and shape of the feed according to the growth stage of different pigs. This precise granulation technology helps to improve the pig’s acceptance of feed, reduce feed waste, and thus improve feed utilization.

4. Strict Screening by Rotary Screening Machine

 
During the feed pelletizing process, the Rotary Screening Machine is used to screen out unqualified feed particles to ensure uniform size and regular shape of the final product. This not only helps to improve the palatability of the feed, but also reduces feed waste caused by too large or too small particles.

Conclusion

 
Through the application of feed granulator, pig farms can achieve efficient conversion and accurate supply of feed, and significantly improve the utilization rate of feed. At the same time, through the recycling of organic fertilizer production lines, pig farms can convert waste into valuable organic fertilizers and achieve sustainable use of resources. This innovative feed processing technology not only helps reduce the operating costs of pig farms, but also improves the overall competitiveness of the pig industry.

Key considerations for fertilizer coating machine selection

Written by fertilizer production line on . Leave a comment

When selecting a coating machine, fertilizer companies should consider their own production needs and focus on three key factors to avoid mismatching the equipment with their production.

First, consider compatibility with the particle characteristics. For large fertilizer particles (diameters over 5mm), a wide-channel coating machine with an anti-sticking guide structure is recommended to prevent particle accumulation and blockage within the channel. For particles with high moisture content (above 12%), a conveyor assembly with an anti-stick coating is preferred. For organic fertilizer particles containing fibrous impurities, it is also important to confirm whether the coating machine is equipped with a pre-filter to prevent impurities from entanglement with mechanical components.

Second, consider capacity compatibility. For small-scale production (daily production capacity under 50 tons), a batch coating machine can be selected, offering flexible batch adjustments and suitable for producing a variety of fertilizers in small batches. For large-scale production (daily production capacity over 100 tons), a continuous machine is recommended to ensure that the conveyor speed is synchronized with the material feed rate.

Finally, consider the compatibility of the coating material. If using PE film, confirm that the equipment’s heat-sealing temperature range covers 100-130°C. If using functional coating materials (such as films containing anti-caking agents), check that the equipment’s tension system supports low-tension adjustment to avoid film breakage and impacting performance. Additionally, pay attention to the equipment’s adaptability to film widths and whether it can be flexibly adjusted to accommodate different packaging specifications, minimizing material waste due to film mismatches.

Optimizing ring die granulators: Key measures to boost organic fertilizer output

Written by fertilizer production line on . Leave a comment

The ring die granulator is a core piece of equipment in organic fertilizer production lines. Its performance directly affects pellet formation rate, production efficiency, and product quality. Optimizing it not only increases output but also cuts energy use and lowers maintenance costs.

1.Die Hole Size and Compression Ratio
Adjust hole size based on material properties: Different organic raw materials (like livestock manure, straw, or sludge) have varying viscosity and moisture levels, requiring different hole sizes (typically 2.5–6 mm).
Optimize compression ratio: Too high a ratio increases energy use; too low affects pellet hardness. Adjust based on material (generally 1:5–1:8).
2.Raw Material Moisture and Fineness
Control moisture at 20%–30%: Too high causes clogging; too low hampers shaping. Adjust through drying or water spraying.
Keep particle size ≤1mm: Finer material improves granulation, reduces return rate, and boosts output.

3.Roller and Die Compatibility
Set roller gap (0.1–0.3mm): Too wide lowers forming rate; too narrow speeds up wear.
Check roller wear regularly: Uneven wear causes inconsistent pellets. Replace or repair promptly.
4.High-Quality Wear-Resistant Materials
Use alloy steel or carburized rings to improve wear resistance and extend service life.
Apply surface hardening to rollers to reduce friction and replacement frequency.

By rationally adjusting the ring die parameters, optimizing raw material processing, and strengthening equipment maintenance, the output and stability of the fertilizer granulator can be significantly improved. This improves efficiency while lowering operating costs, delivering greater value for producers.

What materials can a ring die granulator handle?

Written by fertilizer production line on . Leave a comment

Ring die granulators are widely used for granulation in industries like organic fertilizer and biomass energy. However, different materials vary in suitability. Choosing the right material boosts efficiency and extends the ring die granulator’s life.

1.Organic fertilizer materials

Livestock manure: Chicken, cow, or pig manure can be pelletized into organic fertilizer after fermentation.

Agricultural waste: Materials like straw, rice husks, or mushroom residue can be crushed and mixed into bio-organic fertilizer.

Sludge-based fertilizers: Sewage sludge or biogas residue can be used for pelletizing after dehydration.

Humic acid fertilizers: Blends of humic acid with NPK nutrients make efficient organic-inorganic compound fertilizers.

2.Inorganic fertilizer materials

Compound fertilizers: Mixtures like nitrogen, phosphorus, and potassium (urea, MAP, KCl, etc.).

Single-nutrient fertilizers: Powdered fertilizers (like ammonium sulfate, potassium nitrate) turned into granules.

Micronutrient fertilizers: Materials containing zinc, iron, boron, etc., formed into uniform pellets.

3.Biomass energy materials

Wood pellets: Sawdust, wood shavings, or wood chips pressed into high-density fuel.

Straw pellets: Crop waste like corn or wheat stalks processed into clean energy pellets.

Other biomass: Peanut shells, palm shells, bagasse, etc., processed into fuel pellets.

The properties of different materials (moisture content, viscosity, fiber content) will affect the granulation effect of the ring die granulator. It’s crucial to select the right ring die (compression ratio, hole size).And adjust process parameters (temperature, pressure).
