Coal ash includes a number of by-products produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler. Bottom Ash, a coarse, angular ash particle that is too large to be carried up into the smoke stacks so it forms in the bottom of the coal furnace.

Reflux classification as a recent hydraulic technique was employed to separate macerals by Xie and Tran 17,18 with different emphases. The former was underlining effect improvement and 15% incrment in vitrinite enrichment, while the latter gave a detailed introduction on principles of reflux classification.

Inside the fly ash, there are round- shaped hollow particles whose its density is lower than water of about 0.9 g/cm 3. These particles called cenosphere containing alumino-silicate. Due to its lighter and tougher nature, it makes the cenosphere appealing to use as a lightweight and robust material. Cenosphere can be separated using both dry ...

Three types of separators each with a high-precision method of classifying particles according to size or density. For dry materials of 100 mesh and smaller, air classification provides the most effective and efficient means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment.

Coal fly ash (CFA) is a major global pollutant produced by thermal power plants during the generation of electricity. A significant amount of coal fly ash is dumped every year in the near vicinity of the thermal power plants, resulting in the spoilage of agricultural land. CFA has numerous value-added structural elements, such as cenospheres, plerospheres, ferrospheres, and carbon particles.

Fly ash is typically stored dry in silos, from which it can be used or disposed of in a dry or wet form. Water can be added to the fly ash to allow for stockpiling or landfilling in a conditioned form (approximately 15 to 30 percent moisture), or for disposal by sluicing into settling ponds or …

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).

The technology has been instrumental in enabling recycle of the mineral-rich fly ash as a cement replacement in concrete production. Since 1995, over 20 million tonnes of product fly ash have been processed by the STET separators installed in the USA. The industrial history of fly ash STET separation is listed in Table 3.

Level gauges are meters used to determine the level of a liquid in a fixed storage or process tank.The gauge is composed of several parts including head, float, measuring tape, bottom anchored bracket, guide wires, elbows, anchors, coupling, pipe support brackets, and pipework.

Air classifiers separate materials based on shape, size, and density and are most commonly used in an industrial process involving mixed materials that need to be separated quickly. For example, in recycling centers, an air classifier can sort through metal, paper, and plastics that arrive mixed together.

Specifically, it is the unburned residue that is

Gyrotor air classifiers, or rotating vane air classifiers, separate dry solid particles by size. They are designed for any separation where the fines are 500 microns (35 mesh) of finer. They can handle feed rates from 0.1 to 200 tons per hour depending upon the desired cut point and material density.

The ConJet ® high-density bed jet mill is a spiral jet mill combined with a patented dynamic air classifier. This classifier enables the ConJet ® to achieve highest finenesses independent of the product load, and therefore also highest throughput rates. Applicable for finenesses from 2.5 to 70 µm (d97). Machine sizes available for grinding air volumes from approx. 50 to 2,400 Nm³/h.
