Improving the efficiency of the highly complex cement production process requires sound scientific analysis of the entire manufacturing process (equipment, raw materials, energy demand, fuels, cement portfolio, emissions, environmental protection laws etc.). VDZ’s expertise in cement production, backed by scientific research and proven in practice, our qualified specialist personnel with their extensive knowledge of the latest techniques and measurement technology, accredited laboratories and many years of experience with international service projects allows us to offer our customers technical reviews and energy reviews tailored perfectly to their requirements.
Over the years, VDZ has devised its own assessment rules and applied these in the conduction of technical reviews and energy reviews all over the world. Depending on the review objectives, we offer three types of review (basic, advanced and detailed):
- Basic Review: expert assessment based on available plant data
Basic Reviews utilise data available in the cement works that is supplied to VDZ. An on-site tour is not included, meaning that the plant’s current conditions are not taken into account.
- Advanced Review: expert assessment based on available plant data and on-site inspection (without on-site measurements)
Advanced Reviews supply a more in-depth overview of the condition of a cement work’s technical systems: On-site inspections can identify any unprofitable practices and technical defects. The review produces a report that lists improvement measures and options for cutting production costs and/or proposes further action. If required, detailed analysis of plants, plant sections or processes are proposed, e.g. of cement grinding (Detailed Review, finish mill, kiln plant), quality assurance (Laboratory Review) or maintenance organisation.
- Detailed Review: complex on-site measurements and analysis of results (mass and air flows, emissions, particle size distribution etc.)
Detailed Reviews are recommended if the data quality produced by an Advanced Review is insufficient to justify recommended optimisation measures with high CAPEX (e.g. plant refurbishment) from a costs perspective. VDZ thus always conducts Detailed Reviews with objectives and scopes of measurement specific to the respective customer’s requirements.
The review’s conclusions are compiled in a report that can be produced in German, English or Russian language. The performance indicators used in the report can be agreed individually with the customer in advance. VDZ guarantees that project management, review activities and assessment meet the highest demands regarding technical expertise, accuracy and confidentiality.
