  • Rapid Limestone Calcination Using Microwave Assist Technology

    The endothermic nature of the CaCO3 to CaO calcination indies that heat transfer is a significant issue, as Moffat determined [2], in the calcination of lime. The endotherm means that as the reaction progresses, the material is actively cooling itself, preventing the diffusion of heat deeper into the unreacted limestone.

  • Lime Production from Limestone

    Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.

  • The Role of the Calciner in Producing Soda Ash

    The calciner is used to heat the trona ore to around 300 – 350º F. Heating to this temperature drives off CO2 and some water to yield soda ash that can be further processed into a more pure form. Once trona ore has been processed, the now pure form of soda ash can be utilized in any number of processes to produce the products we rely on ...
