Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges

Get PriceFactors of Safety - FOS - are a part of engineering design and can for structural engineering typically be expressed as FOS = F fail / F allow (1). whereFOS = Factor of Safety. F fail = failure load (N lb f)F allow = allowable load (N lb f)Example - Structural Steel Column in a Building. Due to buckling the failure load of a steel column in a building is estimated to 10000 N.
