Introduction Drum vibrating sifter is essential units which can apply in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum which is normally elevated at an angel at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material smaller than the screen apertures passes through the screen, while the over-sized material exits at the other end of the drum. Drum vibrating sifter used to separate materials by sieve size. Production rates can vary from 20 to 30 yards an hour to several hundred yards of material an hour based on number of factors described in this article. It is consisting of five parts as drum, frame, hopper, reducer and motor, which provide a simple, efficient and economical solution to upgrade a wide rang of material and optimize the subsequent process steps of recovery. Working Principle Drum vibrating sifter consists of five parts as drum, frame, hopper, reducer and motor. After the material into the drum, on one hand, materials being screened along with the rotation of drum, on the other hand, the bigger materials flow forward along the direction of slope and be separated by the screen with different numbers of meshes. The different materials fall into different hoppers and then are sent to different finished product stacks by manpower or belt conveyor. Drum Sifter is essential elements which can apply in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum which is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material smaller than the sift apertures passes through the sieve, while the over-sized material exits at the other end of the drum. Features Steady and smooth operation. Low noise and low energy consumption. Simple structure with easy maintenance. Low dust pollution. Long life span. Suitable to separate various materials especially poor quality of coal and coal slime. Equipment is fully sealed with cover in order to minimize the suspension of fine materials in the air during the operation. High screening efficiency due to installation of comb shape screen structure. Cylindrical shape of the screen provides larger surface area for the materials to in contact with. Able to handle large capacity of materials with high efficiency. Trommel screen sifter can be sealed designed, no dust pollution Special screen mesh design, high screening efficiency, longer service life, less blockage Application Drum vibrating screen is widely used in classifying the solid materials in coal, mining, electric power, light industry and other industries, screening the wet materials in metallurgy, construction industry and chemical industry, too.
