Introduce the Screening Condition about Vibrating Screen

The detailed screening process is that the crude ores are screened for the first time and the new can get two kinds of products which are lump ore and powder ore. The lump ore is screened for the second time and then goes into the shaft furnace for roasting, and the powder ore will directly goes into the strong magnet beneficiation process for screening. The spiral grading machine and hydrocyclone equipment all belong to gravity grading equipment which means that these machines grade materials with the sedimentation theory and the grading efficiency is very low and generally speaking, it is 30% to 40%. Especially when the meaningful ores with large density are graded, they are often accumulate in the returning sand which will result in over crushing of the meaningful ores and the processing ability of the mill machine is reduced and the electricity and metal consumption will be increased.
Vibrating screen is of multilayer and high efficiency( three layers or four layers), it is often used in the behind of Jaw Crusher orImpact Crusher. Hongxing Vibrating screen adopted eccentric shaft vibration exciter and partial block helps to adjust amplitude, this kind of screen is of long stream line,many specifications and clear screening for different specifications. So it is widely used in the industries of quarry, building material,traffic,energy,chemistry, etc. The screening process that we are now stimulating includes the first screening of the crude ores, the second screening before the burning, the fine screening with the strong magnetic and weak magnetic beneficiation and the residue removing screening in the process of the strong magnet beneficiation.
Vibrating Screen means an equipment of screening, it's one of the auxiliary equipments in stone production line. Although Vibrating Screen doesn't like Jaw Crusher or Sand Maker stand core position in the whole production line, it's irreplaceable. Vibrating Screen not only can screening different final sizes, but also it can screening waste garbage.
The rocks that have been crushed are mixed rockes composed of particles of different sizes. Before using them or further process, we often need to grade these rock materials into different levels with different granularity. The grading process of separating the mixed materials with different sizes according to their different granularity by means of the multi-hole working face is called screening. The multi-hole working face is called screening face and the machine with a screening face that is used for grading materials is called a screening machine.
