where d b.max is the maximumsizeof feed (mm); σ iscompression strength(MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of themillbody (m).. Generally, a maximum allowedball sizeis situated in the range from D /18 to D/24.. The degree of filling themillwith balls also influences productivity of themilland milling efficiency.

    Obviously, thecompressive strengthof high volume UFA blended system under steam curing is higher than that of standard curing. The 3-daycompressive strengthof UFA50-A, UFA50-B and UFA50-C was 19%, 13% and 20% higher than that of UFA50-D, respectively. Thecompressive strengthunder the three steam-cured regimes showed a slight difference.
