2 Installation and Operation Manual
1.0 Introduction and Overview
A belt conveyor scale is a device that continuously measures bulk material as it moves along a conveyor. The
system requires two general parameters to operate:
• It needs to know the weight of the material being moved along the conveyor belt
• It needs to know the speed at which it’s moving along the conveyor belt.
The weight of the material on the belt is determined by weighing a section of conveyor belt loaded with material
and then subtracting the average weight of the unloaded belt. The speed at which the material is moving is
determined by measuring the speed of an idler or wheel in contact with the conveyor belt. The weight and speed
is combined to give a running total and a rate of flow of the material. The correct operation of the scale system
requires the components to be installed correctly, periodically calibrated, and properly maintained.
Typical applications where a belt conveyor scale can be used are:
• Mining
• Quarries
• Bulk material blending
• Truck/barge/rail loading
• Process control applications
A belt conveyor scale is also able to compute the total mass of the material that is conveyed over a given period
of time and while it is in motion.
The integrator In-Motion Belt Scale System is durable and one of the most accurate scales in its class. The
integrator easily handles capacities up to 10,000 tons per hour with unsurpassed accuracy. It’s innovative
integrator fits a wide variety of applications - from simple inventory reporting to automated load-out.
1.1 Belt Conveyor Scale System Components
The main components of a basic belt conveyor scale include:
• Scale carriage
• Load cells
• Belt travel pickup speed sensor (not shown)
• Electronic integrator (BCi)
