The rotary drum screener machine mainly consists of motor, reducer, drum device, frame, sealing cover, inlet and outlet.
It is a common equipment in the production of organic fertilizer and compound fertilizer.
The working principle is that the material is divided into 1-4 sections from fine to coarse according to different classification requirements, and the separation of finished products and return material is controlled according to the size of the material, the precision and efficiency are high. At the same time, it has strong adaptability to materials, and can be screened for various properties such as viscosity, humidity, dirt and impurities, the feeding way is diversified, that is, the artificial way and the mechanical transmission, can realize the scale production. The central sieve is made of nylon, stainless steel and manganese steel according to different materials.

Advantages of Rotary Screener Machine:
The sieve hole is not easy to plug, the screening efficiency is high and the service life is long.
The speed of the rotary screen is low, the operation is smooth and the noise is small.
The sieving cylinder is sealed, easy to close and collect dust.
 
In the fertilizer manufacturing process,it is to be equipped with different type and series organic fertilizer machine.It is to be equipped with the fermentation compost turner machine to finish the fermenting process,and it is to be equipped with the fertilizer mixer machine,fertilizer crusher machine of different type to deal with the raw materials.
There,if we produce the bio organic fertilizer into granulator,we can use the fertilizer granulation machine to finish the granulation process,the fertilizer granulator machine type to be designed different type,we can choose the suitable fertilizer granulator machine type to finish the granulation process.
For example,in organic fertilizer production line,we can use the rotary drum granulator,disc granulator and new type organic fertilizer granulator machine to finish the production process.In npk fertilizer production process,we can use the double roller granulator machine to make the npk fertilizer granulator by using the extrusion method.And in the bio fertilizer production process,we can choose the flat die granulator machine to finish the production process to finish the granulation process.Different type fertilizer granulator machine can be used in different type fertilizer manufacturing process sometimes,and it has different type working principle.
