Quality & Environment

MND Enerji provides the cement manufacturer with the full range of quality assessment and quality improvement services. Eliminating poor quality and variability early within the process results in a more stable operating process and improved final product quality and consistency.

MND Enerji Quality Service reviews start with the quarry and quarry operations and follow the process flow through pre-blending, raw milling, blending, pyro-processing and cement milling. The performance of each process stage is evaluated not only against MND Enerji quality and process targets but also takes into account the types of materials used and the desired final product quality required. The quality audit also takes into consideration the impact upon the process in areas such as fuel and power consumption, gas bypass-use and environmental performance to assist the cement manufacturer improve the cost of production at the same time as improving quality performance. The measurement of quality is critical to the cement manufacturing process and MND Enerji can provide laboratory auditing services by an accredited auditor. This process includes assessing the sampling frequency for each process stream, whether the sample is taken in the correct place and in the correct manner, the equipment used for analysing samples and the accuracy of the laboratory equipment.

MND Enerji also provides expert services in areas such as clinker microscopy – critical for understanding the reactions in the kiln and the influence of the raw materials and raw milling process on the final product quality – and product development of various cements such as fly ash cement, slag cement, white cement and oil well cement.

MND Enerji provides the cement industry with advice and support through all levels of environmental improvement, from equipment optimisation to CO2 emission reduction strategy. In the simplest form, this can be assisting in the optimisation of existing pollution control equipment. The next level of support relates to the development of the environmental improvement plan for the plant. This is often required when new legislation is introduced and can relate to changes in materials and fuels and the installation of new environmental protection equipment.

MND Enerji can also make a major contribution to the overall reduction in the CO2 emissions from the cement manufacturing process. The starting point of this process is the optimisation of the fuel and power consumption of the plant and reducing process waste in areas such as the gas by-pass systems. Waste fuels and the use of biomass also play a significant role in the reduction of CO2 per tonne of clinker and MND Enerji experts can predict the process and environmental impact of these fuels as well as design handling and dosing systems of the fuel, regardless of material properties.

MND Enerjis product development specialists can assist in the formulation of cements with higher proportions of cementitious materials and fillers and the optimisation of these cement products. These cements lead to an overall reduction in the CO2 per tonne of cement, as well as increasing the effective capacity of the plant. MND Enerji also advises on the performance of any such new products in concrete
