The whole machine of organic fertilizer drum screening machine consists of a frame, a grading silo, a screening drum and a transmission mechanism. The installed drum of the whole machine is at a certain angle to the ground, so that when working, the material gradually flows from the feed port to the discharge port as the drum rotates. 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 feed ports for powder and large particles are used. When screening granular materials, they are usually divided into three feed ports for powder, finished granules and large particles.

Similarly, when bundling the screen on the drum of the organic fertilizer drum screening machine, the bundling order of different screens needs to be determined according to the position of the grading silo. Because starting from the feed end, the first thing to be screened out is definitely the finest powder material, followed by larger granular materials, and then large granular materials. In addition, the direction should be kept consistent when bundling the screen, so that the rotary screening machine will not retain too much material in the screen when it rotates, ensuring the normal use of the screening machine.

The organic fertilizer drum screening machine relies on the rotation of the drum to lift the material and then screen it. Therefore, compared with the organic fertilizer vibrating screen that relies on the vibration of the screen to screen the material, it can better protect the granular material from being damaged. In addition, the friction between the continuous flow of materials also makes the material look smoother. Therefore, the drum screening machine is particularly widely used in the fertilizer industry, and its use effect is also quite good.
