Bucket elevator design and calculation.

Hello everyone.    Today is a good day for me because I finished the first lunch of the new application about bucket calculation. Its name is " Bucket CalPro "     For the bucket elevator design process, the designer should have knowledge about the bulk materials and standards for design. This tool is used DIN 15234 - Bucket for Elevator. Basic calculation. 1.Volume Capacity   (Qv) = 3.6 * v * φ * (VB / α ) Where : Qv = Volume capacity ( m³/h) v    = Speed (m/s) φ   = Degree of filling. α   = Bucket pitch (m) VB = Norminal capacity (liters) 2. Mass capacity (Qm) = Qv * δ Where: δ     = Bulk density (t/m³) Qm = Mass capacity (tph) 3. Pulley revolution (n) = (v*60)/(¶*D) Where: n = Pulley revolution (rpm) D = Pulley diameter (m) 4. Peripheral force (Fu) = Fh + Fb + Fn Where: Fu = Peripheral force (N) Fh = Main resistance (N) Fb = Loading resistance (N) Fn = Secondary resistance (N) 5....
