Your Rotary Calcining and Drying Experts. Powder Processing & Technology provides contract calcination and drying services using rotary calciners or kilns. We have a broad range of equipment and the know-how to meet virtually any high-temperature requirement. Our gas-fired calciners and our electric kilns can process powders up to 2700 °F.





Calcining is offered in a range of batch kilns both gas and electric fired at temperatures up to 1250 degrees centigrade with capacities of up to 1.5 tonne batch size. Apart from the extensive production scale Calcination Services available Thermograde can also offer laboratory / pilot scale calcining in crucibles with as little as a 200 gramme ...









But there is a huge different in scale: in the cement kiln temperatures reach over 1500°C, whereas clay is calcined at 650-850°C. Calcined clay production thus consumes less than half of the specific thermal energy of clinker production. Even more importantly – and unlike limestone – calcining clay does not release CO2.













Calcination refers to the heating of inorganic materials to remove volatile components. While the decomposition of calcium carbonate to the oxide is the classic example, the process is now a common and important step in the fabrication of a wide range of oxide ceramics, where it is used to improve the processing characteristics in …



This ensures that the catalyst and substrate are well bonded and also hardens the catalyst so it can hold up under duty. In addition, calcination also assists in: ¹. Removing impurities that could otherwise poison the catalyst. Aiding in control of surface density. Finalizing the surface area of the support structure.





Technical Writer. Calcination is the process of heating a solid material in order to cause chemical separation of its components. The diversity of chemical separation lends calcination to accomplishing a range of objectives, from the removal of chemically bound (crystalline) water, to the volatilization of contaminants from a source material ...



















Calcination also known as calcining is a process of heating a solid compound at a very high temperature below its melting point. This process is carried out in the absence of oxygen or a limited supply of oxygen. The process involves heating a substance to high temperatures, typically between 700 ℃ to 1200 ℃, although the …
