Before making organic fertilizer, the pretreatment of raw materials is needed, and these machines may be helpful:

1. Screening Machine

For some organic fertilizer factory which uses industry organic waste as their materials(such as mushrooms, filter mud and biogas residue), it’s better to screen out the extra materials before making them into organic fertilizer. With rotating fertilizer screener, you can make fertilizer more efficiently.

2. Crushing Equipment

Some organic fertilizer raw or auxiliary materials can’t be composted directly because of long or large shape. To solve this problem, you can choose a fertilizer crushing machine, such as semi-wet crusher, cage crusher and so on. They can crush materials into small particles, which can help your fertilizer plant run more smoothly.

3. Dewatering Machine

Dewatering machine is mainly suitable for poultry manures and animal wastes. Manures always have high moisture content, it’s obvious that they are not suitable to be directly made into fertilizer. By using solid-liquid separator machine, the moisture content of animal manures can be reduced to about 30%, which is the appropriate value for making organic fertilizer.
