4.2.1 Control gates
The installation of a material feed control gate or similar device improves uniform flow of
material.
①
Control gate
②
Uniform material distribution
③
Belt scale
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 Head pulley
Note
Use caution when installing a scale in a short conveyor, or when locating the scale near the
head pulley.
Since head pulleys are flat faced, and carrying idlers are generally troughed, the belt profile must
change from troughed to flat in a short distance. To accommodate this, the conveyor
manufacturer designs a built-in vertical displacement of the head pulley above the top of the
center roll of the adjacent idler.
