Calcining Drying ovens


Calcination is a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition. Calcination furnaces are generally used to prepare raw materials for raw processing. 

Calcining Ovens create phase change or remove moisture. 

The function of a Calcining Oven is to heat solid materials or ores to induce phase transition, or for removal of a volatile fraction or crystalline water as water vapor. The system can be specially designed to accommodate a controlled heat-up and release rate from the product. 

Each Industrial Oven project undergoes a comprehensive evaluation of every production requirement. The assessment includes areas such as production goals, part configuration and construction, part mass, temperature profile, and facility location or elevation. 


  • Economical operation is achieved with superior thermal process engineering practices that apply state-of-the-art insulation material, airflow management, and custom programming.
  • Recirculation fans with high efficiency motors to reduce energy consumption.
  • Recirculation ductwork designs provide precise airflow to specific areas of the product resulting in smaller footprint ovens thus reducing utility and factory space costs.
  • High-efficiency (gas or electric) heat sources to reduce energy costs.
  • Robust structural oven frames and component supports.
  • Application specific insulation materials are selected to provide optimum insulating characteristics and long term energy savings.
  • Design considerations for easy access to process areas and oven components.
  • Programmable controllers with HMI (Human Machine Interface) displays allow for user friendly operation and machine diagnostics.
  • Factory tested to ensure on time delivery and field start up.
