Is the drum screening machine only used after granulation?

 Is the drum screening machine only used after granulation? Of course not. Our drum screens are usually equipped with a granulator (double roller granulator, rotary drum granulator, disc granulator machine, etc.) that can help you sieve the finished granules. Also, you can use this machine to sift out trash and small stones from the raw material before composting. Using a drum screen machine can improve the purity of the raw material, so that you can get a high-quality compost manure. If you want to speed up your composting cycle, we can also provide you with a compost dumper.

The sieve is the key part of the drum sieving machine, which is used to sieve fertilizer particles of different sizes. You can adjust the mesh number of the drum sieve filter according to your raw material requirements. Our engineers have adopted three ingenious designs in this machine to improve screening capacity and working efficiency.

Rotary screening machine is a common equipment in fertilizer production. In your organic fertilizer production line and npk fertilizer production line, you can use it to separate finished products and return materials. It can also realize the classification of finished products, so that the finished products can be evenly classified. In addition, before the organic raw material is fermented, the raw material can also be processed with a rotary sieving machine. It can also remove impurities such as plastics and stones in raw materials. After screening, the raw material is purer and can get better compost.

How does the rotary screen separate materials?
First of all, when the rotary screening machine is installed, it will have a certain slope with the ground. Therefore, due to the inclination and rotation of the drum, when the material enters the drum unit, the material will continue to turn and roll.
Then those materials which are smaller than the mesh will roll out from the screen of the screen drum, while the materials which are larger than the mesh are discharged from the end of the drum.
Finally, you can separate your desired particles from other materials.
