Grinding energy requirement and so the grindability nature of the material (limestone in this case) should be addressed in detail. In order to address the comminution behavior of rocks, mostly addressed index is HGI, i.e. Hardgrove Grindability Index.
Effect of Lime Pretreatment on Granulation of Switchgrass
Switchgrass is a dedicated, perennial energy grass native to North America. Upon harvesting, switchgrass is often chopped and densified into bales, compressed into chops or pellets to improve bulk density and to reduce cost of handling, transport, and storage [1–3].Switchgrass bales often require further processing (de-baling and …
An Overview of Lime Slaking and Factors That Affect the …
The following is a brief chemical formula of this process: (Limestone) CaCO3 + HEAT (Calcium Oxide) CaO + CO2. However, CaO is unstable in the presence of moisture and CO2. A more stable form of lime is calcium hydroxide Ca(OH)2. Therefore, 56 units of CaO plus 18 units of H2O results in 74 units of Ca(OH)2.
