Exploring the fertilizer processing technology of roller extrusion granulator
The roller extrusion granulator contains unique secrets in the fertilizer processing process, which have contributed to its important position in the fertilizer production industry. Careful pretreatment is essential before the raw materials enter the r roller extrusion granulator . Organic fertilizer raw materials usually undergo sufficient fermentation to remove harmful substances such as bacteria and insect eggs, while improving the physical properties of the materials. The crushing process is also crucial, as the raw materials need to be crushed to the appropriate particle size, generally controlled at a few millimeters, to ensure the smooth progress of subsequent granulation. When the raw materials that meet the requirements are transported to the feed inlet of the roller extrusion granulator, the granulation journey officially begins. Two rollers rotate towards each other at the same linear velocity, creating a strong squeezing force between them. Under this sq...
