is a modulus reduction factor. The modulus reduction factor can be estimated from the RQD of the rock and the ratio of rock mass modulus to the normal stiffness of discontinuities. Using the average RQD of cores from the load test site, which equals 55 percent, and 1 m (3.28 ft) for the rock

Reduction ratio is often measured by dividing the F80 by the P80. The F80 is the particle size where 80% of the feed material is smaller than that size. The P80 represents a particle size where 80% of the product is smaller. Reduction ratios will vary with each application within each family of Hammermills and by the amount of applied energy.

Although historically the use of limestone (LS) as a construction material dates back to ancient times, when calcined LS or gypsum was used to make mortar (Mayfield, 1990) and when LS became one of the main constituents of the raw feed used to manufacture Portland cement clinker in 1824, it is the acceptance of LS as an addition to cement with Portland clinker (EN 197-1, 2000 ()), to reduce ...

Volume balance with limestone filler V c + V gs + V gw + V cw + V cs = 1 – V LF When the equations are used in this form, it must be kept in mind that w/c in equation set (1) represents the effective water-cement mass ratio and not the water-(cement + limestone) ratio (w/cm), which would typically characterize a limestone-blended cement. resuLts

Reduction Ratio - an overview ScienceDirect Topics. The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the ore.The usual reduction ratio is about 8. According to Bond [4], the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as.
