Abrasive. An abrasive is a material, often a mineral that is used to shape or finish a work piece through rubbing which leads to part of the work piece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes.

Refractory metal oxides. Refractory metal oxides withstand high loads in mechanical and process engineering applications and are highly resistant to heat and wear. With their high melting point, refractory metal oxides are used in applications like bio and dental ceramics, precision investment casting, glass fusion or as catalysts.
Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Figure 11.5-1 illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying.

2. Our bonded abrasives (F-size) have also proven to result in significantly reduced defect ratios during the manufacturing process of grinding wheels compared to regular quality BFA, due to high and consistent bulk density levels. 3. In addition, our F-size abrasives have been tested to increase cutting efficiency of cutting wheels by 20-30%.
Process duct work conveys large volumes of hot, dusty air from processing equipment to mills, baghouses to other process equipment. Process duct work may be round or rectangular. Although round duct work costs more to fabricate than rectangular duct work, it requires fewer stiffeners and is favored in many applications over rectangular ductwork.
