Vibrating Screen
Large stone by the hopper evenly sent by the vibrating feeder jaw crusher for primary crushing, crushing stone after the conveyor belt to the crusher for further crushing; stone after crushing by the belt conveyor Sent vibrating screening plant, screening out of several different specifications of the stone, to meet the size requirements of the stones taken from the finished product conveyor belt stockpile.
Vibrating Screen for Coal Mining
This coal mining project is an open pit mine located in Nigeria, announced by mining company.That has discovered 62,400,000 tonnes of proven reserves of coal deposits worth US$1.2 billion which could be used for the generation of electric power.Coal provides one of the best alternative sources of energy for Nigeria due to its availability, easy usage and high heat emission. Therefore it’s extremely important to choose best suitable coal mining project solution.Our vibrating screens are used to select the different size which meet our customers’ demand.

Vibrating Screen for Copper Ore Processing
The copper ore is then ground finely before the copper-bearing sulphide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate can contain between 25 and 57% copper. The concentrate is then processed in a smelter.We usually choose vibrating screen for copper ore process.
Vibrating Screen Operating Principle
Vibrating screen moves round. It has multi-layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line. 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 vibrating screen for copper ore processing, 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.
Vibrating Screen Operation and Maintenance
- Before starting, we should inspect every fasteners bolt of vibrating screen whether to become less crowded, if it has, we should fasten it one time.
- After the sieve machine has empty motion for 4-6 hours, the sieve body should be steady. No sway and unusual sound and driver bearing temperature≤7512.
- After idle operation movement, we should examine every spots spiral of vibrating screen fastens one time.
- In normal work, it should have periodic inspection of every fasteners bolt tight situation.
