Loesche Technology – a Success Story In 1927 Ernst Curt Loesche patented the world's first spring-loaded air-swept mill developed by him in Teltow near Berlin. And so began the unprecedented career of the Loesche roller grind-ing mill. It all started with the grinding of coal at the Kling-enberg power station in Berlin, the first coal-dust-

VERTICAL ROLLER MILLS
In the 1984, UBE developed the 2-Way System where de-aeration and compaction of the material bed on the grinding table is achieved by sub-roller pressing thereby improving the material coefficient of friction (μ). Over the years, UBE has the well-established 2+2 and 3+3 system of Main Roller and Sub Roller for Cement and Slag grinding.
Mobile grinding mill for ore
To ensure optimal customer support, Loesche provides a specialist plant operator to handle OGPmobile operation and look after the plant, document the test results, monitor setup and dismantling and act as an interface between Loesche and the customer. A Loesche ore team can take care of planning, execution and evaluation of the tests.
