Table 17
MATERIAL CHARACTERISTICS
The values included in table 17 are for
approximate density, abrasive index from 1 to
3 where 1 is non abrasive, 2 is mildly abrasive
and 3 is highly abrasive, and any special
features of the material that should be taken
into account in any conveyor design.
The values in the tables are given as a guide
