Process of coal slurry dewatering on the vibrating screen surface involves three stages: at the first stage, pulp is concentrated to high concentration due to the removal of free water by the action of hydrostatical pressure applied to its layer; at the second stage, high-concentration pulp is imparted with the viscoplastic properties due to …
The vibratory screen is widely used in coal and other industries, used as a material classification, mineral washing, dehydration, and screening machine. It is widely used in mining, coal, smelting, building materials, refractory, light, and chemical industries for its high production efficiency, good classification effect, and convenient ...
Vibratory screening equipment is used to screen or classify wet or dry materials, like wet ash or dry frac sand, into multiple grades by particle size. They are also used to dewater or dry waste material before disposal.
In addition, it should operate at a low stroke with a frequency range of 1500-7200 RPM. Before using a high-frequency screen, it is usually necessary to pretreat the feed, because the holes in the screen are easily blocked. Main application: The high-frequency screen plays a vital role in the various ores beneficiation line.
