Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness. GBFS can be utilized in the cement making process as an

29-04-2017· The paper examines the effect of ball (drum) grinding and jet milling on the particle size distribution and specific surface area of the powders produced from blast-furnace slag. The effectiveness of jet milling, providing relatively equal powder particles (more than 85% of the fractions is 0–10 μm in size), is shown. Decrease in the average particle size leads to greater specific surface

One horizontal milling machine can be as productive as three vertical milling machines. The spindle utilization on an HMC can be has high as 85% compared to a typical 25% for a VMC. The horizontal machining center uses better chip evacuation methods when compared to vertical mills, which means less re-cutting and longer tool life.

25-03-2011· Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.
