How To Make Pellets From Poultry Manure?
After composting, poultry manure becomes grayish brown and has no odor. There may be large agglomerates, bones, and pebbles in the material. So before making pellets, you need to crush raw materials into homogenous powder. In the poultry manure fertilizer making process, many choose to use a semi-vet material crusher.
In order to make the organic fertilizer richer in nutrients, you can add the appropriate amount of trace elements humic acid, and other nutrients. After adding the nutrients, it is necessary to fully mix them with organic fertilizer. If the amount is relatively small, you can mix it with tools by hand. For larger quantities, a blender is recommended.
With all the preparations above, you can begin to make pellets. Common granulation equipment includes disc granulators and drum granulators. Both of them belong to wet granulation. A difference between them is that you can add water during the granulation process if you use a disc granulator, while if it’s a drum granulator, you should add water before materials get into the granulator.
