The chicken manure fermentation granulation organic fertilizer production line is a molding machine that can manufacture materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls.
The chicken manure fermentation granulation organic fertilizer production line utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. This granulation method results in higher ball forming rate, more beautiful particles, and energy saving.
Organic fertilizer extrusion granulation equipment uses dry extrusion technology to compress powder materials with a moisture content of less than 20% into flakes. After crushing, granulation, and screening processes, the flake and block materials are transformed into granular materials that meet the usage requirements. Dry rolling granulation mainly relies on external pressure to force the material to compress into pieces through the gap between two relatively rotating rollers; During the rolling process, the actual density of the material can increase by 1.5 to 3 times, thereby achieving a certain strength requirement.
The advantages of organic fertilizer extrusion granulation equipment over roller extrusion granulation machines:
1. No drying process, room temperature granulation, one-time molding, low investment, quick results, and good economic benefits.
2. Low power and reliable operation, without emission of three wastes; Stable operation, convenient maintenance, reasonable process layout, advanced technology, and low production cost.
3. The raw materials have wide applicability and can be used for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, coal, metallurgy, etc., and can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.).
4. Especially for the granulation of rare earth, ammonium bicarbonate, and ammonium sulfate based compound fertilizers, it fills the domestic gap and ranks at the leading level in China. It is a promotion project of applicable technologies for national environmental protection.
