  • The ABC of steel

    Rolling mill – Any of the mills in which metal undergoes a rolling process. For plate, sheet and strip, these include the slabbing mill, hot-rolling mills, cold-rolling mills, and temper mills. Any operating unit that reduces gauge by application of loads through revolving cylindrical rolls; operation can be hot or cold.

    In ring-roller mills rollers feed solid coarse particles against a stationary grinding ring. The particles are broken apart by the resulting compression forces. Equipment Design In a ring-roller mill, the material to be milled is fed into the grinding section . The moving roller forces the coarse material against the stationary grinding ring.

    An effect of a grinding method, that is ball mill and high pressure grinding rolls (HPGR), on the particle size, specific surface area and particle shape of an iron ore concentrate was studied. The particle size distribution was meticulously examined by sieve, laser and image analyses. To measure the specific surface area of particles, Brunauer-Emmett-Teller (BET) and Blaine methods were used.

  • Effect of Biomass Carbonization on the Grinding of Coal

    However, in existing pulverized coal-fired power plants, the maximum achievable co-firing ratio is limited by the design of the coal mill and grindability of the biomass fuel. Because biomass is more difficult to pulverize than coal using a roller mill, (1) a high ratio of biomass in the feedstock remains unpulverized.
