Equipment composition and operation principle of drum screening machine for organic fertilizer

2022/02/14
The whole machine of organic fertilizer drum screening machine is composed of frame, grading silo, screening drum and transmission mechanism. The drum of the installed whole machine presents a certain angle with the ground. In this way, during operation, the materials gradually flow from the inlet end to the outlet with the rotation of the drum. When used as a fertilizer screening machine, the number of grading silos is determined by the different needs of finished products. When screening powder materials, two inlets of powder and large particles are used. When screening granular materials, they are usually divided into three inlets: powder, finished product particles and large particles.

Similarly, when binding the screen on the drum of the organic fertilizer drum screening machine, the binding sequence of different screens needs to be determined according to the position of the grading silo. Because from the feed end, the finest powder materials must be screened first, followed by larger granular materials, and then large granular materials. In addition, when binding the screen, the direction should be consistent, so that the rotary screen will not retain too much material in the screen during rotation, so as to ensure the normal use of the screen.

The organic fertilizer drum screening machine picks up the materials by the rotation of the drum and then screens them. Therefore, compared with the organic fertilizer vibrating screen, which screens the materials by the vibration of the screen, it can better protect the granular materials from being damaged. Moreover, the continuous flow of materials and friction between them also make the materials look smoother, Therefore, the drum screening machine is widely used in the fertilizer industry, and its application effect is also quite good.
