Coal milling Question 2. We are having a 1.5Mt six-stage Precalciner kiln operating with South African coal having a VM of 28 per cent. Now we thinking to switch over to Indonesian coal with high VM content up to 42 per cent and Chinese coal VM up to 32 per cent. The coal mill.
Safety measures valid for coal yards should be applicable to torrefied biomass pellets. Degradation of torrefied pellets due to climatic effects increase the risk for dust formation for subsequent conveying operations.
Mill the largest surface first. Keep hands, brushes and rags away from the revolving milling cutter. Use a vacuum, brush or rake to remove cuttings only after the cutters have stopped moving. Change cutting compounds periodically. Keep cutters sharpened correctly and in good condition. Keep working surface clear of scraps, tools and materials.
