Introduction Linear vibrating sifter is used to separate materials into various particle sizes for further processing.Basically, professional large capacity mining linear vibrating screen manufacture consists of the screen box, supporting device, driving unit,vibration isolation and etc. It has two operational driving modes: dual-vibration mode (light duty) and dual-vibration exciter mode(heavy duty). Working Principle The vibrating source is also from vibrating motor. There are two motors to be fixed on the both side of screening box(or under the screening box) to corotate on the contrary direction. In the process of rotating, when two motors synchronous reversely rotate, the eccentric blocks of motor will emerge a kind of centrifugal force, which can be transmitted to the screening box and make the machine run by linear direction. Then the material on the mesh will be vibrated forward and screened. There is an angle of inclination two motor axis's relative to screen deck, under the influence of resultant force of exciter force and materials self weight, materials are threw up to make saltatory and linear movement forward on the screen deck in order to screen and grade the materials. By choosing the suitable mesh, the screening target is realized.   Features High productivity Tightness, very little dust spilling, also can be enclosed or can be connected with duct collector. Low energy consumption, low noise and long service life. Screening of high precision, large capacity, simple structure. Fully enclosed structure, automatic layout, Easy maintenance It can be used for assembly line production automation. Sieve body parts are used rolled welded steel plate and profiles (part of the group as a bolt connection between the body) the overall stiffness is good, solid and reliable. Application The linear vibrating screen can be applied to the screening and grading of powder and granular materials. It is widely used in plastics, building materials, metallurgy, rubber, ceramic, food, pharmaceutical, chemical, carbon, abrasives, fertilizer, glass,ceramics and other industries.
