It can choose about 1 5% iron in the tailings At the same time the steel slag powder produced is high in fineness and the specific surface area of the finished product can reach 450~500 m2/kg or more and the activity is good and it is suitable as cement active mixed material and concrete admixture

The objective of this study was to investigate the mechanical properties of wood/plastic composites (WPCs) produced using wood flour (WF) prepared by wet ball-milling under various milling times (0–120 min) and drying methods (freeze- or heat drying) The drying method did not affect the particle size distribution shape or specific surface area of WF at milling times shorter than 40 min

Ball Weight and Density How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material $textWeight = textVolume ⋅ textDensity$ For example calculate the weight of a two inch diameter lead ball $textVolume = {4 ⋅ π ⋅ R^3 }/ 3$
