PE1052 : Quality Control, Raw Materials & Raw Mix Design

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using “MS-Excel” application. 

 

This course is designed to provide participants with a detailed and up-to-date overview of Quality Control, Raw Materials & Raw Mix Design. It covers the importance of quality control in cement plants as well as the physical and chemical properties of cement raw materials; the chemical composition of raw materials covering key oxides, LOI, SO₃, MgO, alkalis and their impact; sampling and sample preparation and material analysis techniques; and the mineralogy and microscopic analysis and its role in problem-solving and quality optimization; the quarry planning and raw material evaluation and raw material variability and control; and the pre-blending techniques and online XRF/PGNAA analyzers for real-time analysis. 

 

Further, the course will also discuss the stockpile management and the impact of quarry operations on product quality and discuss raw mix design, clinker chemistry and mineralogy targets; the key quality parameters in raw mix design comprising lime saturation factor (LSF), silica ratio (SR) and alumina ratio (AR); the raw mix design calculations and burnability and kiln feed optimization; and the corrective materials and mix adjustment and raw mix design for blended cement. 

 

During this interactive course, participants will learn the raw meal quality control, clinker quality evaluation, cement quality parameters and laboratory quality assurance; the standard compliance and product certification covering ASTM, EN, BS, IS standards for cement and troubleshoot quality issues; the integration of QC with process control, statistical process control (SPC) techniques and CONTROL CHARTS AND Cpk/Ppk indices; and the using of software tools in raw mix optimization and the role of chemistry in fuel consumption; and using of low-cost alternative materials, minimize fuel and grinding energy and blend strategies and logistics.
