The current trend in this transport system is to build equipment as compact as possible. To achieve
this equipment operating at high speeds is used. As a result, the intended purpose is achieved, the system size is
reduced also manufacturing costs and selling. The aim is to show that when are exceeded speed limits, the apparent benefits, imply hidden defects, such as damage to the transported material, its return and increased energy consumption per unit of transported volume, as well as premature wear of the equipment. An analysis of existing literature and catalogs of manufacturers show that material degradation during transport or the energy
problem has not been taken into account in the design criteria. In this paper it is proposed the addition of design
guidelines, taking into account the comprehensive study of the problem and in particular the variations suffered
in recent years in the quality conditions for reception and marketing of bread wheat fixed by resolution
1262/2004 of the Secretariat of Agriculture, Livestock, Fisheries and Food of the Republic Argentina, under the name "Quality Standard for Wheat Marketing XX Pan-STANDARD BREAD WHEAT". As a result of the
analysis, there are more robust facilities with a higher initial cost, but with a lower cost per cubic meter transported, with a longer life and proper treatment of the material.
