Conveyor belt specification determining method

A conveyor belt specification determination method, comprising:

• categorizing, into a plurality of categories, a severity of use conditions of a conveyor belt, using a horizontal energy and a vertical energy as indices, the horizontal energy and vertical energy being received by the conveyor belt as a result of objects to be conveyed being fed onto and loaded on an upper cover rubber of the conveyor belt and conveyed;
• creating a database in which a permissible range of each of prescribed characteristics is set for each of the categories, the prescribed characteristics including at least wear resistance and cut resistance of the upper cover rubber;
• setting a representative rubber physical property of the upper cover rubber that affects each of the prescribed characteristics;
• ascertaining a degree of influence of the representative rubber physical property that is set on the prescribed characteristics;
• when determining a specification of the conveyor belt, identifying the category of severity from the use conditions of the conveyor belt on a basis of the database;
• identifying an appropriate range of the representative rubber physical property for which the prescribed characteristics are in the permissible range in the category that is identified;
• and
• selecting a rubber type, for which the representative rubber physical property is in the appropriate range that is identified, as the upper cover rubber.
