Since concrete contains quartz, these tools throw silica dust into the air. Hazardous activities include: Cutting bricks, concrete blocks, and similar materials with a stationary masonry saw. Cutting masonry, block, tile, or rock with a handheld masonry saw. Grinding surfaces for finishing and cutting slots with hand-operated grinders.
Granite sludge waste (GSW) is produced during the granite quarrying process especially in the sawing and polishing process. Water is used in a large amount in equipment for cooling and lubricating. The amount of water used differs from one factory to another according to the amount, size and types of sawed blocks per year.
In this new method that uses three-stage flue-gas treatment, lime (calcium hydroxide, or Ca (OH) {sub 2}) shows cost and operational advantages, and could displace limestone (calcium carbonate, or CaCO {sub 3}), the traditional favorite. For flue-gas treatment in the electric utility market, limestone currently dominates the scene.

Water stains are one of the most common sources of stains on granite countertops, and they generally occur in two forms. The first — and easiest to clean — is a simple water stain that forms around the bottom …
Wet Sweeping: Wet sweeping with regular water spray will moisten and control silica dust, after which it can be removed from the surface using industrial scrubbers. Water Flooding: Water flooding will prevent silica dust particles from becoming airborne. The sweeper is then used to collect wet silica dust and bits and control exposure.
They found that adding granite sludge enhances the engineering properties of the CSEBs with water absorption less than 10% and wet compressive strength ranging between 3.5 and 7.8 MPa. While Swaminathan et al. [ Citation 4 ] studied the possibility of using granite and marble sawing waste in the production of bricks.
1. High-quality feldspar produced in pegmatite: hand selection – crushing – wet grinding – classifying. 2. Feldspar in weathered granite: washing – crushing – grinding – classification – flotation (removal of iron and mica or separation of feldspar and quartz). 3. Feldspar in fine crystal rock: crushing – grinding – screening – magnetic separation.
From classification the sand, at 70 to 75% solids, is introduced into a Attrition Scrubber for removal of surface stain from the sand grains. This is done by actual rubbing of the wet sand grains, one against another, in an intensely agitated high density pulp. Most of the work is done among the sand grains — not against the rotating propellers.
Description In wet scrubbing processes, liquid or solid particles are removed from a gas stream by transferring them to a liquid. The liquid most commonly used is water. A wet scrubber's particulate collection efficiency is directly related to the amount of energy expended in contacting the gas stream with the scrubber liquid.
