Roofing Granules: Crushed to a fine particle size, crushed limestone is used as a weather- and heat-resistant coating on asphalt-impregnated shingles and roofing. It is also used as a top coat on built-up roofs. Flux Stone: Crushed limestone is used in smelting and other metal refining processes. In the heat of smelting, limestone combines with

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).

However, due to particle size and enhanced initial reactivity, the effectiveness is short lived, compared to regular agricultural limestone, and will probably have to be repeated every year. Suspensions may also raise soil pH slightly above the target pH, and they are a considerably more expensive way to correct soil acidity.

This is main because limestone particle size (2.5–5 mm) is easier to be crushed into small sizes (0–2.5 mm); the weight lost for sample E (particle size 1:1:1:3) is lowest. This means that the larger particles were difficult to be crushed into fine particles.
