A grinding aid composition useful in grinding granulated blast-furnace slag by a roll press process, comprising: [which is comprised of] an aqueous solution having dissolved therein from about 10 to 50 weight percent polyacrylic acid of a weight average molecular weight of at least 25,000 or its alkali metal salts or mixtures thereof; and said ...
The paper sums up the results of observations made during the commissioning of the roller press (RP) for slag grinding for TISCO cement project. At the time of selection of the RP technology for this project, there was not adequate experience available in regard to the process and design parameters leading to series of problems during start up ...
The roller press can be combined with static and/or dynamic separators to achieve high recovery of pig iron in slag grinding, while at the same time providing high grinding fineness. Stefan suggests that roller presses use around 3-5kWh/t less compared to a VRM to grind slag to the same fineness, or, using the same specific energy consumption ...

The slag grinding plant in Nanchang is in operation since November 2005. The roller mill is a type RMS-51/26 with an SEPOL RMS-435 separator. For a feed material consisting of 95% slag, 4% gypsum and 1% limestone a capacity of 80t/h finish product with a fineness of 4400cm 2 /g according to Blaine was warranted.
Combined grinding technology of roller press was an organic combination of roller press and ball mill, which integrated the high-efficiency and energy-saving features of roller press and the wide particle grain size distribution, uniform particle group shape and good particle morphology of fine slag powder produced by ball mill.
Heavier dust pollution, as the roller press system's circulation is large, and conveying by the belt and elevators. Lower noise under normal operation: Heavier noisy with ball mill in the system: easier adjust grinding fineness and grinding different types of materials, such as cement, slag, etc;
