The process of NPK fertilizer production line mainly includes raw material ratio, crushing, mixing, granulation, drying and cooling, screening, packaging, etc. The fertilizer granules obtained through the NPK fertilizer granulator need to go through drying, cooling, screening and other processes. The good fertilizer granules are sent to thin coating and packaging by the screening machine, and the unqualified fertilizer granules are sent to be processed again.
Drum screener machine is a commonly used equipment in the production of compound fertilizer. The machine has simple structure, convenient operation and stable operation. It adopts combined screen, which is easy to maintain and replace. The drum screener machine is composed of a frame, a grading silo, a screening drum and a transmission mechanism, the installation of the machine and the ground presents a certain angle, so that when working, the material with the rotation of the drum from the feed port end gradually flow to the outlet. When used as a fertilizer screener machine, the number of grading bins is determined by the different requirements of the finished product. For example, when screening powder materials, only two feed ports for powder and large particles are used. When screening granular materials, usually It will be divided into three feed ports for powder, finished granules and large granules. The drum screener machine relies on the rotation of the drum to pick up the material and then screen it. Therefore, compared with the vibration screener machine, which relies on the vibration of the screen to screen materials, this machine can better protect the granular materials from being damaged. And through the continuous flow of materials, they will generate friction with each other, which also makes the materials look smoother, so the drum screener machine is particularly popular in the fertilizer industry, and its use effect is quite good.
