effective way to prevent and remove buildup elements such as Na, Mg, AI, Si, P, S, Cl, K, Ca problems. and Fe can be determined in a total measuring time of 300 sec. The determination of traces of The new PowerBlaster air cannon features an Cl in cement is one of the strengths of the innovative design providing more cleaning XEPOS-Cement analyser. The measuring force than other air cannons, and at the same condition are: time, also solves the major problems typically caused by traditional air cannons. Many plants have silos and hoppers that are used for material storage. Often, the material being stored in these vessels will become cohesive, creating material flow problems such as bridging and rat holing. The PowerPunch offers and effective and inexpensive solution to this problem. Halcyon Technologies can effectively deal with all types of buildup. Its innovations will allow cement plants to eliminate unscheduled downtime for manual cleaning, improve kiln efficiency, and reduce so2 and NOX emissions in ways not possible before.

Heckel, Spectra Analytical Instruments, Germany, XRF is usually employed for the analysis of raw meal and cement. With the introduction of the XEPOS-Cement analyser a compact benchtop instrument, it is now possible to perform quantitative analysis of major, minor, and trace elements in rawmeal and cement with excellent precision and detection limits. All important • • • Tube voltage: 25 kV. Tube current: 1.6rnA. Typical spectrum of a cement sample The results clearly show that the precision of the XEPOS-Cement analyzer rna tche s the demands of the cement industry. It is also capable of measuring all major, minor and trace elements z;:::n and can be used for QC– measurements of cement prepared as Lithiumtetraborate glass.

L. Smidth & Co. into the new global F. L. Smidth has seen a spin-off in the form of a redesigned air-to-air heat exchanger available to its entire organisation, facilitating project and order processing on either side of the Atlantic. There is mounting demand in Europe for air– to-air heat exchangers that comply with the rapidly rising emission standards. Today, nearly 90% of all new plants are provided with such heat exchangers. The specific aims of updating the machine to European standard were to
