Abstract
The authors of this article developed the tabular form of numerical calculation of the screw
conveyors. The tables allow solving the next problems: the change of internal screw geometry, the
definition of ability to transport the loads of different materials, the calculation the mass of the load
in the interturn space, the increase of performance if we have got a powerful electric motor. In this
article it shows the application of the formula for determining the geometric, kinematic and load
characteristics of the screws. In each table formulas are the interrelationship of computing
processes. These formulas can be used both the sample calculation for development of such devices,
and for master benchmarking of existing screws.
