Research of the speed flows of the charge on the surface of the rolls of the press-rollers extruder

摘要

In the production of building materials,the processes of grinding and extruding the mixture with roll-type units are accompanied by uneven wear of the working bodies as a result of uneven distribution of material across the width of the rolls,which subsequently affects the quality of the finished product.In addition to the above,feeding the charge to the edge of the press plane rolls in the press-roller extruder leads to a bolted joints thread extraction of the fixed side surface.In this article,based on the results of analytical studies of the movement of the charge process to the forming zone,a possible solution of the emerging problems with press-roll extruder working bodies of uneven wear was proposed and argued.
