Principles of Mineral Processing and How Inclined Screens

On a large-scale mineral processing deck, moving parts orient themselves when aggregate loads drop free of vibratory feeders. Everything about the equipment feels kinetically charged, so there are motors buzzing and powered solenoids snapping shut. Still, among all the energized machine parts, inclined screens are performing their own role in the mineral processing sequence.

High Frequency Sizing Screens 911Metallurgist

By classifying by size-only, screens compared to hydrocyclones, give a sharper separation with multi-density feeds (for example, in Pb—Zn operations), and reduce overgrinding of the dense minerals. To date, 1000s of screening machines are in operation at mineral processing plants worldwide. Dry mass flow capacity typically ranges from 100

Mineral Comminution and Separation Systems

mineral processing is to adjust the size of mineral particles to adapt to the optimum size for the successive separation processes. Screens and classifiers are used to adjust the particles within prescribed and closer size range. They are arranged in many cases in conjunction with the equipment for ‘size reduction’, or ‘comminution’.
