Beyond Bernoulli19 October 2015, Published under Cement NewsDr Clark considers the flow of gases through the cement kiln process and some of the governing principles and complexities. Preheater exhaust gas flows are an important source of recoverable energy A recurring theme of the Technical Forum has been the fundamental mass balance of a cement kiln and the mass flows into, through and away from the cement kiln system. The subject of this month’s article are the mass flows in the exhaust gases and particularly the preheater exhaust.... |
What cement users want01 July 2015, Published under Cement NewsDr Clark returns to the topic of cement product development looking at how the properties of cement can be modified to suit different concrete and mortar applications. Cement producers need to develop products that are most required by construction companies to gain an advantage over their rivals In December 2014 while participating in a workshop on “innovation products for strategic growth” organised by Považská Cementáren in Slovakia, the Technical Forum focussed on the top... |
Deep-dive benchmarking11 June 2015, Published under Cement NewsDr Clark is finally able to talk about his involvement in an innovative project to improve the performance of supplier/service provider to the international cement industry. The real value of deep-dive benchmarking is reflected in the recommendations made on how to change the cement plant’s operations to become better than the competition Around 18 months ago the moderator was involved as a cement industry expert in a “deep-dive” benchmarking project on behalf of a supplier/s... |
Production accounting20 April 2015, Published under Cement NewsDr Clark muses on the complications of cement production accounting and the estimation of the physical inventory stocks of in-process materials. The monitoring and accounting for physical inventories is not without challenges February’s Cemtech Middle East and Africa in Dubai was again an informative event enjoyed by all participants. For the moderator it was a particularly busy time as a three-day technical workshop was delivered for 26 people from cement companies in Angola, I... |
A chimney of corruption17 November 2014, Published under Cement NewsDr Clark recounts how statistical analysis of the variation in product quality control testing can be used to detect the corrupt reporting of testing results as one particular case of a cement company comes to mind. This method can help avoid the spectre of expensive lawsuits and damage to the cement maker’s reputation. Figure 1: clinker free lime distribution – typical skewed results On a quiet, misty autumn morning the moderator was contemplating the subject of his next Techni... |
