· At present, No. 2 coal and No. 9 coal are mainly mined. No. 2 coal has the characteristics of high ash, low sulfur, good grindability and medium selection. The brand of coal is anthracite and lean coal. After washing and processing, it can be used as power coal for power plant and coal for blast furnace injection.

Dealing with particle abrasion wear in coal processing . Unfortunately, desliming is a high-wear process, and the screens used to filter and separate are continuously subjected to extremely harsh conditions. That means maintenance, repair and costly downtime — or at least it used to. FL Desliming Screens are changing all of that.

Coal cleaning process. Sep 20, 1994 0183 32 An advantage of one embodiment of the invention is that it provides a process for desliming of raw feed coal prior to beneficiation which minimizes the amount of coal discarded as slimes and aids in subsequent magnetic particle recovery and dewatering of the coal product...

 ·  Desliming and screening is the operation of coal preparation plant in order to reduce the pollution of high ash fine sludge to clean coal. In the process of dewatering on the sieve, water jet washing is strengthened to remove part of the fine sludge. Desliming and screening are mostly used in heavy-medium coal preparation plants.

Effects of Desliming and Hydroacoustic Cavitation ... ABSTRACTTesting was conducted to evaluate the effects of desliming in combination with hydroacoustic cavitation (HAC) treatment on flotation when processing nominal -150 μm Illinois-basin bituminous coal, which was obtained from a refuse stream at an operating coal-cleaning plant.
