What are the differences between calcite mill and limestone mill?

Posted: 2019-03-23

There is a customer consultation about such a question: “Is there any difference between a calcite grinding mill and a limestone grinding mill?” So what is the difference between the mills that process these two materials? Let's take a look today.

First, compare the hardness of the two materials. We know that the hardness of the material is one of the important characteristics of the mill. The density of limestone is 2.94 g/cm3, the Mohs hardness is 3.5-4, the hardness of calcite is 3, and the relative density is 2.6-2.9. Because limestone has a higher hardness, the wearing parts wear faster when the limestone is processed. So the same equipment to process calcite is better.

Of course, what kind of equipment to choose depends on some properties of the material itself.

Calcite: Calcite is a kind of calcium carbonate mineral, which is common in natural calcium carbonate. Therefore, calcite is a widely distributed mineral. Calcite has a variety of crystal shapes, and the aggregates thereof may be a cluster of crystals, or may be granular, massive, fibrous, stalactite, earthy, and the like. Knocking calcite can get a lot of square pieces, hence the name calcite.

Limestone: The main component of limestone, calcium carbonate (CaCO3). Lime and limestone are used in large quantities in building materials and industrial raw materials. Limestone is directly processed into stone and fired into quicklime. The quicklime absorbs moisture or adds water to become slaked lime. The main component is Ca(OH)2. The slaked lime is formulated into a lime slurry, a lime paste, etc., and is used as a coating material and a tile adhesive.

Shanghai Clirik Machinery Co., Ltd. designs the corresponding mill for different materials according to the characteristics of the materials, so that it can achieve large output and large efficiency during processing. For more information on stone mills, please feel free to contact us online.
