In recent years, with the guidance of national policies and the development of agricultural green modernization, organic fertilizer products have become more and more popular due to their advantages such as improving soil, restoring soil fertility and recycling waste. As a result, farmers'awareness of use and market acceptance have been continuously improved, which has become one of the new development directions of fertilizer industry.

Source of organic fertilizer raw material: the raw material for processing organic fertilizer is widely available and inexpensive, and even the treatment of livestock and poultry excrement in areas with large farms has become their difficult problem. The difficult reason is that most of the fresh livestock and poultry excrement has a high water content and is difficult to handle, which leads to no one to purchase. The most prominent problem is the laying hen farm, where the water content of egg and poultry excrement is very high. It is quite a hassle to deal with, so it would be a great pleasure for the surrounding farms to benefit from the fact that the organic fertilizer processing plant would solve the source of raw materials. Raw material cost can be controlled at least to 0.
Organic fertilizer drum pelletizer is a forming machine which can make materials into specific shapes. Rotary drum pelletizer is one of the key equipment in compound fertilizer equipment industry, which is suitable for large-scale production of cold and hot pelletizing as well as high, medium and low concentration compound fertilizer. The main working method is wet pelletizing of aggregates. Through a certain amount of water or steam, the basic fertilizer reacts sufficiently after humidifying in the cylinder. Under certain liquid phase conditions, with the help of rotating movement of the cylinder, the material particles are agglomerated and globulated by extrusion force.

At present, many regions of the world have formulated corresponding laws and regulations for environmental pollution caused by livestock and poultry manure. It is required that the treatment scheme for environmental pollution of existing livestock and poultry farms be put forward, and the principles of harmlessness, reduction and resource must be followed in the treatment and disposal of livestock and poultry manure.
