Roller grinding and water spray system in a vertical mill


The purpose of the training is to Identify and understands necessary known and unknown information towards the completed cycle of the grinding system, whether is a ball or vertical mill. Throughout the course the lectures are supplemented with exercises and case studies, allowing the participants to relate the course material to their cement grinding facility and as a result understanding the changing needs of cement producers and how to tailor solutions to meet those needs. Optimizing output, improving efficiency and reliability, while keeping production costs to a minimum comprise some of the topics covered in this course.

Learning outcomes

An emphasis on the understanding of the milling technology system:

Gas flow, advantage and disadvantage in the Raw mill and Cement mill installations – Grindability concept and the effects of inter-grinding materials of different grindability – Ball mill grinding equations and dimensioning – Describe working principles for a separator – Grinding aids and other tools to boost efficiency – Control concepts – Influence of the grinding process on cement quality – Evaluation of performance and optimization of ball mills, roller presses and vertical roller mills.

Hands-On Practice

A unique combination of theoretical and practical skills throughout this course will be learned, which will assist you to develop and execute the concepts and technical knowledge acquired in the daily activities of operation and maintenance.
