Circular vibrating screen mainly consists of the screen box, screen, vibrators, vibration reduction spring, etc. Vibrator is installed in screen box lateral plate, spinning by motor through the triangle belt, producing the centrifugal force, and forcing screen box to vibrate. Circular vibrating screen is applicable for classifying stone stock in the production line of sandstone; Circular vibrating screen is widely used for classifying products in such industries as mine, building materials, transportation, energy resource, chemical industries, etc. It is the ideal equipment in the crushing and screening equipment group.
Illustration of our circular vibrating screen operation: In screen grading, the material is separated mechanically on screen plates. Rolling bearings invibrating 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 misalignments between the bearing locations and considerable shaft deflections have to be accommodated.
The screening order of vibrating screen in its applications commonly includes the following three points:
1, sequence method: screening from the fine to the coarse.
It is convenient to maintain and easy to observe the work of the screen layer sieve. In the process of screening the fine to the coarse, arrandeing in accordance with the screen surface to screen hole increased order.In addition, the uniaxial vibrating screen sieve can along the entire length of the screen surface respectively eduction.
2, overlapping method: screening from coarse to fine.
The shifters of the linear vibrating screen superimposes one by one in the process of its screening from the coarse to the fine, the upper overlap the larger screen mesh, the following each layer of the sieve mesh JianXia gradually.
3, joint method (mixed screening) :in this process, a part of the shifters arranges from the coarse to fine , and the othe part of the shifters arranges from fine to coarse. In the production practice, circle vibrating screen usually sieves from coarse to fine or joint screen.As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior high frequency mineral screen, quartz grinding machine, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
