Ore separation screening and classification | PPT
Ore separation screening and classification. Jul 31, 2017 •. 24 likes • 8,972 views. Prof. A.Balasubramanian. Ores are typically sorted to increase the efficiency of other refining processes, by reducing the amount of material to be processed while simultaneously increasing its purity. This module explains the ore separation processes.
SCREEN CAPACITY CALCULATION
The total capacity of a deck is "A" multiplied by the area of the deck in square feet. This is the final result of the multiplication of all the screen factors. 6 "S", the "Incline" factor, depends on the actual slope of each deck and the opening size of the wirecloth.
Vibrating Screen
Overview. Introduction: The high frequency vibrating screen is a mechanical device for screening, classifying and filtering granular materials, commonly used in mining, industry and laboratories. High-frequency screens are widely used in mineral processing, such as screening of iron ore, tin, tungsten, tantalum, niobium, alluvial diamond, etc.
