For the dry grinding of mineral and ceramic raw materials the agitator bead mill NETZSCH SpheRho ® impresses with very high product fineness and high throughput rates with low specific energy consumption.. For decades, agitator bead mills from NETZSCH have been successfully employed in a broad range of industries for the grinding and dispersing of suspended solids.
Its use allowed the collected ash to be carried through pipes at faster conveying rates and farther distance from the boiler. ASH introduces the Hydrovac™ pneumatic vacuum conveying systems for the transport of fly ash to the sluices. A new line of fly ash components is developed to combat the wear of abrasive fly ash moving at high velocities.
analysis of fly ash is an important factor in the quality evaluation process par ticularly as it relates to strength gain ing factors in concrete. A marketing agent, John Ashby of Pozzolanic, Inc., told the audience there are ample supplies of fly ash available in Kentucky since the state is only utiliz ing about three percent of reported
Nowadays, the reuse of waste products in the construction process is a priority research area. Several industrial and agricultural waste products have been investigated, such as fly ash, sugar cane bagasse ash and rice husk ash. This paper analyzes a very important aspect under intense discussion in the scientific community: the Rice Husk Ash (RHA) grinding process.

Thus, fly ash is a residue predicted to increase significantly in the coming years. Only a small percentage of fly ash is used in concrete production, road base construction, soil amendment and zeolite synthesis the large majority is still discharged into ash ponds, lagoons or landfills (Imbabi et al., 2012).
The fly ash comes from small drops of melt and volatile compounds which are carried up by the ascending gases. The mixture of gases is cooled in a refrigerating system where fly ash solidify at temperatures from 950°C to 400 °C. Afterwards, the fly ash is separated and recovered from the filters in the gas cleaning unit.
ZEOLIFICATION OF ASHES OBTAINED FROM THE COMBUSTION OF SOUTHERN'S BRAZIL CANDIOTA COAL Lizete Senandes Ferret1, Iolanda D. Fernandes1, Carlos A. Khahl1, Júlio C.

Analyzing the microstructure of the fly ash, it is observed that it is composed by void spheres and plerospheres (void spheres filed with smaller ones). Having that in mind, it was studied the admix strength gain promoted by the grinding of de fly ash on a ceramic ball mill, aiming an enhancement of the reactivity of the material.
rule, fly ashes with high SiO2 and Al2O3 contents. The sum SiO2+Al2O3 is regarded as of paramount importance for zeolifiion purposes. The basic composition of the ashes, on the other hand, is presented in Table 2. Coal ash content and ash composition analyses carried out according to, respectively, ASTM D3174 and ASTM D4326.
