The national standard for the production equipment of bio organic fertilizers is that each gram of fertilizer must reach 20 million beneficial microorganisms. This poses a challenge for producers, which is that they cannot produce at high temperatures, otherwise it will kill beneficial microorganisms and the product will not meet the standards. In order to meet the product standards and achieve a certain temperature during drying, the traditional solution is to lengthen the drying equipment of the biological organic fertilizer production line and use low temperature and high air volume for production. This not only increases the cost of equipment, but also increases the production plant, increasing investment and making production difficult. In order to solve this problem, the company’s engineers collaborated with Zhongduo customers for analysis. Based on years of practical experience, the engineers boldly explored and innovated, and finally developed a simple and easy to operate multi-functional granulation process. Due to its fast granulation speed, high ball forming rate, and product yield, the process has been developed..jpg)
The roller extrusion granulator equipment needs to be dry, produced at room temperature, and the product is rolled and formed to meet the technical requirements of compound fertilizers. It is used for the production of high, medium, and low concentration specialized compound fertilizers for various crops, as well as energy-saving and consumption reducing updated products in the compound fertilizer industry. It is also suitable for granulation of various raw materials such as chemical feed.
The main features of the roller extrusion granulator equipment are:
1. The drying process of roller extrusion granulator is characterized by room temperature granulation, secondary molding, low investment, fast effectiveness, and good economic benefits.
2. Compound fertilizer roller extrusion granulation has low power and reliable operation, three waste discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology, and low production cost.
3. The roller extrusion granulator has a wide range of applicability for raw materials, and can be used for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, coal, metallurgy, etc. It can also produce various concentrations and types of compound fertilizers (including organic fertilizers, organic fertilizers, biological fertilizers, magnetized fertilizers, etc.).
4. The roller extrusion granulation machine, especially the granulation of rare earth, ammonium bicarbonate, and ammonium sulfate based compound fertilizers, is a promotion project of national environmental protection applicable technology.
