The roller grinding mill technology, patented in 1928 and continuously developed since then, has become synonymous with Loesche''s pioneering engineering knowhow. CEMENT BLAST FURNACE SLAG CEMENT RAW MATERIAL
Loesche is contributing three vertical roller mills, one each for raw material, coal and clinker/slag. One 4roller mill with a capacity of 450 t/h will be used there for the grinding of cement raw material to a fineness of 12 % with a sieving residue of R 80 μm.
Vertical roller mills, especially those common for grinding of cement raw materials, typically employ a hydraulicpneumatic system to apply a grinding force to the material bed. During operation, these systems will contain pressurized hydraulic fluid in an isolated branch of the circuit consisting principally of cylinders and accumulators.
