Circular vibrating screens are often referred to as vibrating screens. It is a vibrating screen with a circular vibrating trajectory, specially designed for the screening of materials and stones in quarries. It can also be used for product classification in coal preparation, mineral processing, building materials, electric power, chemical and other departments.
The production capacity of the circular vibrating screen is 15-600 tons per hour, and the maximum feed particle size does not exceed 200 mm. Applicable materials are granite, basalt, diabase, shale, quartz stone, river pebbles, limestone, iron ore, coal gangue, non-ferrous metal ore, pebbles, etc. The screen machine of the circular vibrating screen is mainly composed of a screen box, a screen, a vibrator, a damping spring, a base frame and other components. The circular vibrating screen is a kind of screening equipment, with movable parts such as screen box exciter as the mass, metal coil spring as the elastic element, and vibrator as the excitation mechanism, with a single mass forced vibration system. The motor drives the exciter through the tire coupling, and the high-speed rotation of the eccentric block generates a strong centrifugal force, which makes the screen box carry out a forced continuous circular movement. Powered by this movement, the material is continuously thrown on an inclined sieve surface, layered as it is thrown, and screened through the particles when it falls, and the particle size classification is done again and again.
The circular vibrating screen has the advantages of novel structure and advanced technology; The processing capacity is large and the screening efficiency is high. The cylindrical eccentric shaft vibrator and the deviation block are used to adjust the amplitude, which is easy to use and easy to maintain; At the same time, the spring steel braided screen or punched sieve plate is adopted, which has a long service life and is not easy to block; Rubber vibration isolation springs are also used, which have a longer service life, less noise and more stability through the resonance area.
The circular vibrating screen is basically placed at the end of the production line. Through the circular vibrating screen, the particle size required for the material crushed by other crushers can be obtained, and the material of each particle size can be better screened. It plays a vital role in the production line.
