Module 1 

Grinding Technology and Raw Material Preparation

Raw material preparation and cement grinding are the first and the last major process steps during cement production. The energy demand of these two processes amounts to up to 75 % of the electrical energy used in a cement plant. This training will enable participants to obtain a better understanding of the comminution processes and the equipment used for material grinding to ensure high levels of availability,availability optimise production rates and reduce energy consumption.

Learning objectives

  • Overview of all relevant aspects of the cement manufacturing process up to the application of cement in concrete.
  • Attaining fundamental knowledge of raw material preparation and cement production with regard to comminution processes, equipment used and quality analysis.

Target groups

  • Production personnel
  • Process and control room operators
  • Young engineers

Number of participants (min. - max.)

  • 10 – 20


    Raw materials extraction

    • Mining operations
    • Quality control in the quarry
    • Raw material homogenisation

    Quality parameters

    • Understanding powder characteristics
    • Particle size analysis
    • Specific surface according to Blaine / BET - method 

    Grinding technology

    • Ball mills
    • Vertical roller mills (VRMs)
    • High pressure roller mills
    • Classifiers / tromp curve
    • Open and closed circuit grinding
    • Impact of grinding systems on cement properties
    • Optimisation of grinding equipment 

    Module 2 

    Clinker Production and Material Technology

    Clinker production is the most energy-intensive process step in cement manufacturing. It can represent up to 90 % of the total energy demand in a cement plant and is therefore a main focus not only with regard to cost optimisation and quality improvement of the final product, but also regarding emission control and the reduction of impacts on the environment. VDZ’s training will enable participants to obtain a deeper knowledge of the clinker production process and a better understanding of the impacts of the daily decisions of plant personnel on the plant’s performance (quality, electrical energy use, fuel consumption and emissions).

    Learning objectives

    • Attaining fundamental knowledge of cement manufacturing technology (material and burning technology), including the interconnection of sub-processes, process optimisation, emission abatement and efficient use of energy.

    Target groups

    • Young engineers
    • Production personnel
    • Technical staff
    • Process engineers
    • Quality and laboratory managers

    Number of participants (min. - max.)

    • 10 – 20


    Material technology

    • Characterisation of raw materials
    • Clinker formation and clinker phases
    • Clinker properties and effects on product qualities 

    Raw material preparation

    • Blending beds and homogenisation silos
    • Raw meal uniformity and quality control

    Clinker production and burning technology

    • Preheater, calciner, rotary kiln, burner, cooler
    • Clinker burning reactions
    • Alternative fuels and effects on burning process
    • Circulation phenomena (chlorine, sulphur, alkalis, etc.)
    • Energy efficiency 

    Environment and emissions abatement
    (dust, NOx, SO2, organics, trace elements,...)

    • Emission monitoring
    • Emission abatement techniques



    • Presentations
    • Interactive exercises
    • Team work
    • Group discussion
    • Experience exchange
    • Practical exercises
    • Final exam (if requested)


    The training courses are led by experienced engineers and highly specialised researchers.


    The participants will receive a certificate of attendance.
