The vibrating screen is machinery and equipment of vibration screening, which is suitable for damp fine grade of difficult materials with dry vibration screening, and is also equipment to process difficult materials of the domestic. Vibrating screen has the process characteristics of large amplitude, large vibration intensity, low frequency and elastic screen surface. In the working process, it maintains the largest rate of hole, which is of high efficiency, large capacity, convenient replacement of sieve plate, and reduces the cost.
Details about Vibrating Screening Process
The screening process can be divided into three stages, 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.
The detailed screening process is that the crude ores are screened for the first time and two kinds of products can be got: powder ore and lump ore. The lump ore will be screened for the second time and then goes into the shaft furnace for roasting, and the powder ore will directly go into the strong magnet beneficiation process for screening. Hydro cyclone equipment and spiral grading machine belong to gravity grading equipment which means that these machines grade materials with the sedimentation theory and the grading efficiency is very low. Generally speaking, it is 30% to 40%.
It is a new multilayer, highly efficient vibrating screen. It can be used in mine, construction, electricity and chemical department to take classify function. It has the advantages of reliable structure, strong exciting force, high screening efficiency, small vibrating noise, simple maintenance, safe operation and so on. Likewise, the linear vibrating screens are also widely applied to screen dry materials in ore dressing, building materials, water and power, light industry and building materials.
