The drum screening 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. 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.
