Coal/Coke/Fly Ash Applications for Attritors

Coal/Coke/Fly Ash Applications for Particle Size Reduction Equipment Although they’re often lumped in one category, coal, coke and fly ash are each a different material. Coal, of course, is the fuel mined directly from the ground, while coke is a form of coal that’s been heated in the absence of air and is most frequently used in iron ore smelting.

Comparative study on the characteristics of ball-milled coal …

 · High-energy mill (HEM) has a wide application in material preparation, activation and synthesis. In the present study, fly ash was selected to be milled by HEM under the speed of 700 rpm and the ball-to-powder ratio of 10:1 by weight, but varied periods of milling time. The changes in physical and morphology properties of the milled fly ash were determined using BET …

Mechanisms of mechanochemical activation during …

 · The ball grinding process is conducted using a planetary ball mill (MITR-YXQM-40L) to activate the inert aluminosilicate of HAFA. The alkali grinding process is studied under different conditions. Milling time (t), rotational speed (r), mass ratio of alkali to HAFA (A/H), and mass ratio of the grinding ball to the mixture (B/M) are varied and examined.

"Color Removal from Pulp Mill Effluent Using Coal Ash …

In this study, Coal Fly Ash (CFA), a byproduct of coal combustion power plants, was used as an adsorbent to remove color from locally-obtained pulp mill effluent (PME). Batch adsorption studies were conducted to determine the adsorption parameters that would result in the maximum color removal from PME at the lowest CFA dosage and process cost. The effects of operating variables on color ...
