Volume Flow

Theoretical volume flow (lv)v =1 m/s (quoted in m/h) with 3-part equal length carrying idler arrangement, conveying speed v =1 m/s and the "equivalent" * angle of repose =15

* An explanation of the term "equivalent" angle of repose is given in the notes of DIN 22101.

The theoretical volume flow lvat a conveying speed v is calculated as follows from the values (lv)v =1 m/s according to the above table: lv =v(lv)v =1 m/s.

The conversion of the volume flow lv (quoted in m/h) to a amss flow lm (quoted in t/h) is calculated with bulk density p of the material handled (quoted in t/m) according to table 1: lm = lvp.
