4.2 Conveyor considerations
4.2.1
Control gates
The installation of a material feed control gate or similar device improves uniform flow of
material.

Note
Ensure steady and uniform material loading to the belt at or near the same speed as the
conveyor belt.
4.2.2
Conveyor belting
Variations in the number of belt plies, the cover thickness and the type and number of splices in
a given belt cause considerable change in the weight per unit length of the belt. During the
course of zero calibrations, belt scales average the weight of the belt over one complete circuit
of the belt. Large deviations from the average adversely affect the zero calibrations.
4.2.3
Conveyor curvature
Vertical curvature (varied heights on one belt) is common in conveyor design, but creates
difficulties for belt scales if not dealt with correctly. The curvature, whether concave (internal) or
convex (external), disturbs the idler alignment, if the scale is installed in the area of curvature.
The concave curve tends to lift the belt off of the idlers in the area of curvature as belt loading
decreases, adversely affecting the zero calibration.
Note
Avoid locating the scale within the tangents of scale curvature.
