What Machines are Needed for Preprocessing Organic Fertilizer?

1. Separation equipment
For some factories that uses domestic wastes as raw material, they should employ separation equipment to screen debris like plastic fractionlet and short iron wire out of the raw material.
2. Crushing machine
For some overlong and overlarge raw materials, they can not be used directly. Therefore, you should use crushing machine to make them into small and short particle. For example, stalks, straw and tree branches are hard to be composted and they need to be crushed into small particles before the composting process.
3. Solid-liquid separation machine
Some manure material can not be used directly, because the water content of it is too high. At this time, you should use solid-liquid separation machine to decrease the water content of the manure material firstly, then you can compost the processed material.
