Abstract.

A two-dimensional model of gas-jet mill ejector assembly  has been developed basing on classical ejector scheme. Principal difference of this model from the classical scheme is a channel for supplying additional energy resource. Additional gas is supplied along the accelerating channel periphery through the slots in the wall. In this model, it is possible to modify design parameters of the elements in order to study extent and nature of impact of the flow geometrical parameters on the underlying stream character.

Stages have been established for researching, with the help of  the two-dimensional model, character of the accelerating tube walls wear and methods of preventing it.

The article presents scheme and description of the model. The described model allows to study a possibility to protect the accelerating tube mill against the wear by supplying additional energy resource.

Keywords:

two-dimensional model, wear, ejector assembly, an additional supply of energy resource, supplying slots.
