Rheological behaviors in wet ultrafine grinding of limestone
The rheological behavior of original limestone slurries (<100 μm) is transformed through different types of flows with increasing solids concentration. The use of Dispersant S40 can improve the slurry flowability by decreasing viscosity and eliminating Casson yield stress. It is therefore used as a grinding aid for the wet ultrafine grinding ...

What Can You Use To Cut Limestone? (How To)
Step 3: Cut – Guide the limestone through the wet saw to cut it. Avoid the temptation to push it through quickly because that will likely cause chipping and cracking at the second edge. Allow the saw to do the work for you. Step 4: Shape – One other step that can be taken is to use a sander to smooth out the edge.

Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
