How to granulate limestone powder?

Granulating limestone powder into a more manageable and usable form is an essential process across various industries. This transformation not only facilitates ease of transport and application but also enhances the material’s effectiveness in numerous applications. In this context, understanding the suitable raw materials for granulation and the specific machinery involved is crucial.

What types of limestone are ideal for powder granulation, and why?

Granulation processes typically require raw materials that possess certain characteristics to ensure the efficiency and quality of the final product. For limestone powder, the ideal candidates are those with a fine particle size, low moisture content, and uniformity in composition. These include:

  1. Calcitic Limestone: Rich in calcium carbonate, this type is perfect for industries like agriculture, where soil amendment and pH balancing are required.
  2. Dolomitic Limestone: Containing both calcium and magnesium carbonates, it’s particularly valuable in the production of glass and steel, aside from its use in agriculture.
