Cow Manure Pelletizing Equipment Making Cow Dung Organic FertilizersSpeaking of cow dung in the farm, people feel it terrible. It pollutes the environment, which badly influence the living life of the around residents. One cow produces approximately 40 kg of dung, and in a farm are hundreds of cow, then how to deal with the cow dung? Actually, the cow manure has plenty of nutrition that the plants need, it is the ideal choice that making the cow dung into organic fertilizer. For a farm with 500 cow, building a small complete cow manure pelletizing equipment is very suitable.
Why the cow dung can be made into organic fertilizer?There are many elements inside of the cow dung, including 14.5% of organic matter, 0.30～0.45% of nitrogen, 0.15～0.25% of phosphorus and 0.10～0.15% of potassium, is one kind of valuable resource used for soil fertilizer in planting industry. The organic matter and nutrition content inside of the cow dung is low, with fine texture, high moisture content, slow decomposition, low calorific value, belonging to slow-acting fertilizer. The cow dung has lower nutrition content than chicken manure, pig manure (the nitrogen, phosphorus, potassium content are low), what’s more, cow dung is cold organic fertilizer, with slow decomposition speed than chicken manure, pig manure, therefore, the fertilizer efficiency is much slower than chicken manure and pig manure.
Cow Manure Organic Fertilizer ProcessingCow dung organic fertilizer has two technical process including raw material compost and commercial organic fertilizer pelleting in the cow manure pelletizing equipment.
Raw Material CompostBefore composting the raw materials, you should preprocess the cow dung and rice husk, thus meeting the fermentation requirement of moisture and carbon nitrogen ratio. The moisture content of cow dung has big difference, in the farm the moisture can be 60%-80%, so that you should take some measures to decrease the moisture to 50%-60%. It is suggested that cow dung moisture adjustment adopts returning and mixing method to decrease the moisture, which means that add the cow with low moisture(about 30%) after fermentation into the cow dung material with high moisture, thus the total moisture content can be reduced after dry and wet material mixing efficiently.
