Feb 04, 2011· Limestone is a sedimentary rock. Limestone is a sedimentary rock found near the surface of the Earth''s crust. It tends to acidify and erode when in contact with water containing dissolved carbon dioxide or a weak carbonic acid. The main constituent of limestone is calcium carbonate. Limestone exhibits several unique physical properties.
Limestone superfine mill is mainly used for processing various nonflammable and explosive mineral materials with Mohs hardness below and humidity below 6%. It is widely used in coatings and paint industry, pharmaceutical industry, rubber industry, paper and ink industry, clinker industry, etc.
The water hardness is expressed by an index, or total hardness, TH, in degrees, each degree determined by the following formula: 1 degree (°F : French unit) = 4 mg/liter of calcium or mg/liter of magnesium or 10 mg of limestone. The waters are classified according to their TH (French TH) 0 to 6 degrees very soft water
The hardness of stone is measured by Mohs hardness as a unit of calculation, Mohs hardness in the 6~7 (F=14~20) are hard stone, such as Quartzite and Granite; Mohs hardness between 3 to 5 (F=8~14) belong to the mediumhard stone, such as Marble; Mohs hardness in 1~2 (F=2~6) are soft stone, such as limestone and dolomite etc.

Alkalinity is often related to hardness because the main source of alkalinity is usually from carbonate rocks (limestone) which are mostly CaCO3. If CaCO3 actually accounts for most of the alkalinity, hardness in CaCO3 is equal to alkalinity. Since hard water contains metal carbonates (mostly CaCO3) it is high in alkalinity.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...
