New liners to a cement group in Tanzania


Estanda has provided new liner designs for a horizontal mill cement to Lafarge MBeya Cement Co. cement group.

The project consisted of a complete substitution of the first chamber lifting liners and the replacement of the second chamber classifying liners with modifications to the design to prevent the liner breakage detected in previous cycles. New steel materials were used achieving a cement grinding process optimization and an improvement in productivity of up to 7%. This project was carried out on a CM-1 cement mill, with a diameter of 3.4 m at a cement group plant in Tanzania.


In addition to supplying all components, the assembly of these parts and the grinding installation commissioning was performed.


This was a project to improve the production and to reduce maintenance costs in the cement grinding process.
