Bentonite Calcination

Bentonite Calcination Plant India

Calcinating bentonite is a necessary process to make the raw bentonite clay both highly reactive and strong by removing moisture and changing its composition. In this process, the clay shows improved characteristics, like better adsorption, higher porosity, and lasting chemical stability, which make it fit for applications including foundry sand binders, drilling muds, bleaching earth used in oil purification, iron ore pelletizing and removal of pollutants and earth purification.

We offer rotary kilns designed especially for processing bentonite. The extraordinary heating system in our kilns gives the material better and more consistent results. Since our calcination units are made for strength, use energy efficiently, and can be configured to your needs. We secure automated settings, heat reuse methods, and robust material management tools to ensure high reliability and efficiency.

Features of Bentonite Calcination

• Enhanced Swelling Activation – To improve efficiency, the machine activates the swelling effect of bentonite, which is most helpful in sealing barriers and in drilling muds where expansion is very important.
• Volatile Content Reduction – When the temperature is precise, bentonite is fully freed of organic impurities and moisture while becoming purer with better industrial uses.
• Improved Pelletizing Performance – Calcined bentonite provides stronger green pellets while minimizing the iron ore binder used in steel plants.
• Thermal Phase Stabilization – The system enables stable conversion of montmorillonite to forms better suited for industrial purposes at high temperatures application.
• Advanced Process Integration – The rotary kiln is able to work with upfront crushing, drying, and downstream milling or blending equipment for a fully automated process in one plant layout.
