Drum sand screen machine is a commonly used screening equipment, its working principle is through the rotation of the drum to achieve the screening and separation of sand and gravel. As the drum rotates, the sand is subjected to centrifugal force to roll forward along the inner wall of the drum. At the same time, according to the different size of sand and gravel, will produce different rolling speed and rolling direction. Due to the large inertia, the large particles of sand and gravel will roll forward along the inner wall of the drum and gradually slide down, and finally be discharged from the tail of the screen machine. The small particles of sand and gravel will be subject to the resistance of the drum rotation, and cannot obtain sufficient centrifugal force, so they will be retained inside the drum. In this way, the sand and gravel will be divided into different grades according to its particle size, and the screening of the sand and gravel is realized. In addition, the roller screen sand machine is also equipped with a suitable screen, which can further screen out finer sand and gravel. The roller screen sand machine can not only be used for sand and gravel screening, but also commonly used in industrial fields such as ore classification and beneficiation. It has the advantages of simple structure, convenient operation and easy maintenance, so it has been widely used and favored. In the future development, the roller sand screen machine will continue to improve and innovate to meet the needs of all walks of life.

Structure diagram and introduction of shaftless drum screen

Shaftless roller screen is a kind of equipment upgraded and updated on traditional roller screen. The equipment consists of motor, reducer, screen body, reinforcement ring, supporting wheel, frame and hopper. The shaftless roller screen is applicable in a wide range of fields, and there is almost no restriction on the screening materials. This design not only improves the yield and screening accuracy of traditional screening, but also improves the safety and service life of shaftless drum screen.
