d = average limestone particle size after grinding, ft. Qw = flow rate of water, ft3/sec = density of slurry lbm/ft3 You should take into account: The velocity, V, must exceed that at which sedimentation and clogging would occur. The formula for grinding power is not valid for a particle size below 0.0008 ft (particle size after grinding).

Agricultural limestone, made by crushing limestone to a fine particle size, and lime made by burning limestone in a kiln are widely used in aquaculture. Limestone is comprised of calcium carbonate (CaCO 3) and magnesium carbonate (MgCO 3) in various proportions. Limestone consisting only of calcium carbonate is called calcite, while that

Limestone contactors can mitigate corrosion in small water‐supply systems that use dilute, acidic water. As water is transported through a packed bed of crushed limestone, CaCO 3 dissolves and the pH, calcium‐ion concentration, and alkalinity increase. Operation of a contactor can be effectively modeled by considering the rate of dissolution and interfacial transport of calcium ions.
