Circular vibrating screens 3YK2160 delivers to Indonesia

Circular vibrating screens, also called circular-motion vibrating screens. They are used to classify medium to coarse-grained bulk materials (5.0 mm to 400 mm) for screening. Circular vibrating screens operate using indirect excitation of the screen mesh. The entire screen frame is driven by unbalance masses, which produce a circular vibrating motion. The vibrating screen is widely used in mining, building materials, transportation, energy, chemical and other industries of product classification.

Background

Clients from Indonesia has a stone crushing plant and wanted to replace the odd vibrating screen to improve the quarry plant efficiency. We suggest the vibrating screen 3YK2160. It is a 3 deck gravel screening machine.The screen mesh size is 2100x6000mm. While screens made of fixed mesh have been used in material processing, their effectiveness is greater when they're made to oscillate. Now this vibrating screen 3YK2160 is sent to Qingdao port for loading and shipped to Indonesia.

How to improve vibrating screen?

1. Add a distributor

For the uneven distribution of the funnel, the funnel is modified, and a distributor is added at the belt unloading point. The distributor can move left and right according to the deviation of the belt, and evenly distribute the ore into the two side funnels and enter the circular vibrating screen, so that the feeding on both sides is relatively balanced, which solves the problem of uneven feeding. At the same time, the material of the screen is also changed.

2. Reduce the height difference and adjust the position of the feeding funnel

For the problem of excessive impact force, by reducing the height difference between the discharge end of the funnel and the feeding end of the circular vibrating screen, the ore flows into the circular vibrating screen very smoothly, which greatly reduces the impact force of the ore on the circular vibrating screen, makes the circular vibrating screen more balanced, and effectively solves the problems of box cracking and longitudinal beam fracture. At the same time, in order to solve the problem of uneven distribution of ore at the feeding port, the feeding funnel position is widened at the feeding port, so that the material is evenly distributed on the entire screen surface, which greatly improves the screening efficiency.

3. Increase the slope of the screen surface and improve the ore moving speed

The ore moves slowly on the screen surface, resulting in thick ore accumulation on the screen surface and severe ore compression. The main factors affecting the moving speed are the amplitude of the circular vibrating screen and the slope of the screen. The amplitude is adjusted by adding an eccentric block. In production, the practice of adjusting the amplitude of the circular vibrating screen shows that the effect is not obvious. Therefore, in practice, the angle of the circular vibrating screen is generally adjusted. When the feed amount remains unchanged, the slope of the circular vibrating screen is increased, which increases the running speed of the ore and reduces the residence time of the ore on the screen.
