Trolex pressure sensors have recently been installed at Lafarge Cement in Derbyshire, UK as part of an upgrade to their kiln process cleaning system.



The two kilns each have their own cleaning systems and 80 of the Trolex TX6114 pressure sensors have been used in each system. The Lafarge cleaning process comprises air blaster cannon systems to fire automatically at regular intervals to blast any build-up of material such as shale, limestone and clinker that may settle in the kilns.



The Trolex pressure transducers monitor the pressure lines and measure the pressure in the cleaning air pressure vessels providing analogue trends of the cleaning cycle pressure. This enables the viewing of the discharge and re-charge of the vessels and the trends provide diagnostic information for analysis of system efficiency and operation.
