Dry Reflux Classifier Fly Ash
Recovery and concentration of buoyant cenospheres using …
The objective of the present study is to evaluate the potential for an Inverted Reflux Classifier (IRC) to efficiently separate and recover cenospheres from fly ash. The standard Reflux Classifier (RC) is a separation device that consists of a fluidised bed with a set of parallel inclined channels mounted above (Fig. 1a).

Beneficiation of coal fines using the Reflux™ Classifier
The size analysis results is shown in Fig. 3 and it is evident that the ash distributed uniformly across all sizes. The ash content of the dried feed was 28% and the average particle size (D 50) was greater than 500 μm.Proximate analysis shows that, the sample was found to contain 1.4% moisture, 21% volatile matter and 50% fixed carbon.

Separation of unburned carbon from coal fly ash: A review
Coal fly ash contains rich black carbon (BC) that is generated by insufficient combustion during the process of coal-fired power generation. Siderite (FeCO 3) and pyrite (FeS 2), two of the most common iron ores in coal, can be easily to combine with black carbon to form magnetic mixtures, leading to serious environmental pollution.The …

A Review on Seperation of Cenosphere from Fly Ash
In present day scenario the most valuable component of fly ash is cenosphere. Cenosphere is a light weight, inert hollow sphere filled with inert air or gas. Cenosphere are hard and rigid, water proof and insulative. Typically 1 to 300 μ in diameter.

A Review on Methods of Cenosphere Separation from Fly Ash
Cenospheres are valuable material contained inside the fly ash. Its low weight, low density, and high strength made it very versatile and can be used in various fields. The way of separating the cenosphere from the fly ash consists of two categories, wet and dry separation. For wet separation, it involves submerging the fly ash inside a …
