plants. To keep the rate of the cement production in the plant N°1 as constant as possible, while the kiln is in a technical arrest, clinker from à second plan was carried out and was grinded. The grinding of clinker represents a step of manufacture of cement which consumes about onethird of the power requiredo t produce 1 ton of cement.

Chemical process industries are running under severe constraints, and it is essential to maintain the endproduct quality under disturbances. Maintaining the product quality in the cement grinding process in the presence of clinker heterogeneity is a challenging task. The model predictive controller (MPC) poses a viable solution to handle the variability. This paper addresses the design of ...

Section snippets Experimental work. The same lots of Portland cement clinker and natural gypsum (CaSO 2 O) were used in this industrialplantscale experimental work to eliminate the potential effects of variations in the feed to the grinding systems. Chemical compositions of the clinker and the gypsum, measured by Xray fluorescence analysis, are given in Table 1.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary ...

Chemical analysis. For all clinkers sample, chemical analysis was performed. In accordance with European standard EN 1962 and chemical analysis instruction in Bizerte Cement CB (North of Tunisia), the amounts of CaO, Al 2 O 3, Fe 2 O 3, and MgO were determined by complexometric titration, the sulfate content was determined by nephelometric turbidity, and chloride content was quantified by ...

Abstract: About onethird of energy required to produce one ton of cement is consumed in grinding. There are many factors affecting the energy consumption during clinker grinding. The energy consumption in the cement mills varies between 30 to 50 kWh/ton. Clinker grinding test was conducted in a laboratory mill, 500 mm x 500

Cement Milling. Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse ...
