Vibrating screen for stand alone or multiple installations are manufactured in a wide range of sizes for varying application and production demands. Each unit is compatible with all screening systems and can be integrated into existing and current processing plants. Applications: It is efficient screening machines for the classification of bulk material such as coal, minerals, coke and more It is designed for especially screening stone stock of quarry and also for classifying and screening products of such departments as coal separator, mineral processing, building materials, electricity and chemical industry, cement production line, water conservancy and hydropower, transportation, smelting and etc. Working principles: The barrel-type vibration exciter is installed in the middle part of the machine. During normal operating, the vibration of exciter will drive the screen mesh fixed on the screen box vibrate and then materials will be screened. The big and small materials fall from the upper side and lower side of the screen to get them separated in screen grading, the material is separated mechanically on screen plates. Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads Moreover, the bearings, while rotating about their own axis, perform a circular, elliptical or linear vibrating motion. This results in high radial accelerations, which additionally stress the bearings and especially the cages, considerably the operating speeds are usually very high. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignment between the bearing locations and considerable shaft deflections have to be accommodated. Features: Simple and dependable eccentric type system High screening efficiency and capacity Firm and durable construction Strong violent vibration force Convenient maintenance and safe operating Low consumption and small vibrating noises, long lifespan Technical Parameters:
