Programme overview
Introduction:
Cement plant operations, covering raw mix, kiln burning, clinker cooling and cement grinding, is a 10-day course for process, production, quality and maintenance engineering teams in cement plants that ends with a Kiln Line Performance Audit and Optimisation Plan for a case plant. Plants lose clinker output and margin when kiln feed chemistry drifts, cyclones block, rings and red spots force kiln stops and mills overgrind, pushing heat and power per tonne above target. Nominees already run or support kiln and mill sections and learn through inspection walkthroughs built on real line data. CoreConcept Training Center delivers this cement plant operations course.
Course Objectives:
- Design and correct raw mixes using lime saturation factor, silica modulus and alumina modulus targets and burnability results
- Diagnose preheater, precalciner and burning zone behaviour from gas analysis, pressure profiles and clinker phase data
- Resolve kiln rings, unstable coating, red spots and repeated kiln stops with documented operating responses
- Optimise grate cooler recuperation, fuel substitution and burner settings to reduce specific thermal energy per tonne of clinker
- Control ball mill and vertical roller mill circuits and blended cement quality against EN 197-1 and ASTM C150 cement types
- Audit a kiln line against heat, power, run factor and emission indicators and rank optimisation projects
Target Audience:
- Process engineering teams responsible for kiln line stability, heat balance and raw mix control
- Production teams that run raw mills, kilns, coolers and cement mills on shift
- Quality control and laboratory teams responsible for raw meal, clinker and cement chemistry and testing
- Mechanical and electrical maintenance teams that support kiln, cooler and mill reliability
- Technical services and energy teams that track plant KPIs and lead improvement projects

Why Attend This Course:
- Deliver a Kiln Line Performance Audit and Optimisation Plan for a case plant to the plant manager and the technical director for approval
- Decide raw mix corrections, burner and cooler settings and fuel substitution rates using moduli, gas analysis and heat balance evidence
- Avoid unplanned kiln stops, off-specification clinker and excess heat and power per tonne that erode plant margin
- Share raw mix spreadsheets, kiln upset response sheets, heat balance templates and KPI dashboards with process and production colleagues
Conclusion:
Back at work, the participant gives the plant manager and the technical director a Kiln Line Performance Audit and Optimisation Plan that sets the heat and power gaps, the main causes of kiln stops and quality deviations, and a ranked list of optimisation projects. Management uses it to approve process changes, fuel substitution steps and maintenance budgets, while shift teams use its response sheets during upsets. After the first quarter of operation under the plan, the unit should review kiln run factor, specific heat consumption, clinker factor and cement strength trends.
Frequently Asked Questions (FAQ):
What should participants know before a cement plant operations course on kiln burning and cement grinding?
Participants should already work in a cement plant process, production, quality or maintenance role and read DCS trends and laboratory results. Bringing recent kiln feed chemistry, heat consumption and kiln stop records helps them apply the walkthroughs and the audit to their own line.
How does a cement plant operations course differ from a refractory maintenance or concrete technology course?
It follows the whole cement process chain, from raw mix design and kiln burning to cooling, fuels and cement grinding, and optimises it as one line. Refractory courses cover lining installation and repair, and concrete courses cover mix design and site placement of concrete.
Why do cement plant operations depend on lime saturation factor and the silica and alumina moduli?
These moduli set how easily the raw meal burns, how much liquid phase forms and how much alite the clinker contains. Holding them steady keeps free lime, coating and heat consumption under control and avoids rings, dusty kilns and weak cement.
What do participants take back from the cement plant operations course?
Participants take back a Kiln Line Performance Audit and Optimisation Plan for a case plant, with a raw mix spreadsheet, preheater pressure profile review, kiln upset response sheets, a heat and power balance and a KPI benchmarking dashboard they can adapt to their own line.
