Selftuning adaptive control of cement raw material

The annual cement consumption in the world is around 1.7 billion tonnes and is increasing by 1% every year 1. Cement industries consume 5% of the total industrial energy utilised in the world 2. A total of 40% of the total energy consumption of a cement plant is used in clinker grinding in a ball mill to produce the nal cement taking into account the cement type ground and the power absorbed. Subsequently the attenuation of main uncertainties leads to improvement of the regulation performance.

Robust Model Predictive control of Cement Mill circuits

Robust Model Predictive control of Cement Mill circuits

Cement fineness is an important quality parameter in the cement grinding process. However, very few studies have been done for soft sensing of cement fineness in the grinding process. Moreover, most of the grinding process modeling approaches have been reported for ball mills and rarely any modeling of vertical roller mill Methods and systems for controlling a cement finishing mill, and operating the mill at an optimal point, are disclosed. To determine an optimal point of operation, values of mill power and sound are collected and compared to values predicted by a model to determine if the mill is choking. This choking determination is used in one of two processes to determine an optimal point of operation for ...

An example of cement kiln is discussed and the control rules of fuzzy logic controller are compared with a protocol for controlling cement kiln in other studies. The initial set of rules for fuzzy logic controller is often not the best set of rules and hence there is a need to tune the controller. Cement manufac-turing is highly energy demanding, and is dependent on the availability of natural resources. Typically, the consumption in a modern cement plant is between 110 and 120 kWh per ton of produced cement 1. The grinding stage represents about 40% of the total electrical energy consumption of the cement
