Course Description

Objective
Having skilled team plays a key role in the optimal utilization of the grinding installation in the cement plant. The operators and process engineers must be able to evaluate all the process variables in order to optimize the production economy. This course
provides an in depth understanding of grinding theory and maintenance of the equipment and gives you the tools to audit your own installation.

Learning objectives
The purpose of the course is to give operators, supervisors, process and maintenance engineers tools to optimize the output of an existing cement grinding installation.

Benefits
By having a thorough understanding of the plant power consumption, proper process control and a full understanding
of the equipment and grinding theory, the participants will be able to evaluate and optimize any existing grinding
installation and thereby boost the production rate.
