The production of biological npk fertilizer has become the choice of most biofertilizers. Bio NPK fertilizers come in two forms, one in powder form and the other in granular form. The two manufacturing processes are different. Так, you should choose the suitable equipment to make NPK biofertilizer.

Спочатку, two or three kinds of nitrogen, фосфор and potassium particles are crushed to screen them to the appropriate size. Тоді, after grinding, you can use dynamic feeders to meter the qualified powder biofertilizer according to the scientific proportion. In order to ensure the uniformity of mixing, you can also use a bio fertilizer mixing machine to stir evenly. Після змішування, you have a powdered biological npk fertilizer.

Granular bio fertilizer is the secondary processing on the basis of powdered biological fertilizer production. By using a Гранлятор біоферилізатора, you are able to produce qualified microbial fertilizer pellets. Після грануляції, in order to easily store, Використовуйте a барабанна сушарка to reduce the moisture of biological fertilizer particles. Then a cooling machine is used to control the high temperature. A coating machine can coat the bio npk fertilizer particles. Packing is the last step in the whole production line.
