Sheet-flow-wetting combined with on-tool local exhaust ventilation is an effective engineering control for reducing respirable dust exposures during engineered stone edge grinding and blade cutting. On the other hand, addition of local exhaust ventilation to some water-spray-wetted tools may reduce the effectiveness of the wet method.

The 8-hr TWA concentrations for respirable dust ranged from 1,100 to 4,300 μg/m3 on Day 1 and from 890 to 3,400 μg/m3 on Day 2. None of the 8-hr TWA samples for respirable dust were higher than the OSHA limit. Two 8-hr TWA samples were higher than the ACGIH limit of 3,000 μg/m3 (Figure B2). Figure B2.

For the purpose of the research, eight alternatives to the glass grade silica sand production process are designed. The process designs are based on the project solutions of [5 7] and the environmental impact studies performed by [8,9]. An equipment and machinery database is generated for the sake of the design and material flow analysis.

11.5.1 Process Description1-2. Refractories are materials that provide linings for high-temperature furnaces and other processing units. Refractories must be able to withstand physical wear, high temperatures (above 538°C [1000°F]), and corrosion by chemical agents. There are two general classifications of refractories, clay and nonclay.
