With the right series of processes and set of production line machinery, it is possible to turn cow dung into a high-quality compound pellet fertilizer. One of the most important pieces of machinery in your production line will be a cow manure fertilizer pellet machine also know as a granulator. There are many different types of granulators in the market place and some are better for commercial cow dung granule making than others. Some of the most commonly used granulators in the fertilizer manufacturing industry are disc pan granulators, flat die pellet mills, rotary granulators, double roller granulators, etc.
The four main processes involved in turning cow dung into commercial fertilizer granules are drying, composting, crushing, screening, cow dung compost granulating and bagging. If required you can do bulk blending to a make high-grade mixed fertilizers. It is generally a good idea to mix cow dung fertilizer powder with another type of fertilizer powder in order to improve the nutrient profile of the end product and reduce the moisture content of the granules.
For small scale cattle manure fertilizer plants, a disc granulator is likely to be the best option. Disc pan granular are low cost, easy to operate and require little maintenance. Top models can offer granulating rates exceeding 93%. A typical small scale disc granulator has a capacity of 0.1-0.2 tons/hour, a rotary speed of 21 revolutions per minute and a 1.5kw motor. You can buy cow manure disc pan pellet machines with capacities up to 4 tons/hour.
The truth is that cattle manure is causing massive environmental problems in many locations. Even though it contains lots of micronutrients, in untreated form, it also contains harmful microbes and pathogens, which can pollute water suppliers. Furthermore, cow manure can’t be applied directly to crop soil before composing because the fermentation process generates lots of heat that can burn crop roots. So, being able to recycle cow dung and turn it into high-quality crop fertilizers using the right composting machines and cow dung manure fertilizer pellet machines is now very advantageous. What’s more, you can make large profits from an efficient cow dung fertilizer pellet production line.
Here are some of the advantages of fertilizer pellets produced from cow dung:
1. The pellets have a comprehensive nutrient profile. They contain NPK elements, as well as many micronutrients like calcium, silicon, and magnesium. The pellets change the soil composition and promote crop growth.
2. Commercial cow dung granules contain enzymes and microorganisms that can enhance enzymatic and biological activities in the soil. These activities can improve the accessible nutrient content of the soil for crops as well as beneficially alter the soil pH. Changes in soil pH can help prevent root diseases.
3. As the cattle waste fertilzer pellets promote disease-free roots and prevent root rot by improving the drainage properties of the soil, there is less need for farmers to use commercial pesticides.
4. Cow manure fertilizer pellets are easy to transport and store. The best granulating machines produce high-density pellets, which can be stored in piles for long periods without deteriorating.
