Does Production get the feeling that they are running blind? Profitability depends on good, quality information being available to the decision makers. Good decisions cannot be made on incomplete data and much of the essential information comes from conveyor belt scales. Accurate reporting of material feed tons at the input and output of the plant is critical for efficiency control.
Are your scales assisting or adding to the problem?
So often it is better not to weigh than to weigh incorrectly – no answer is better than a wrong answer! We have found that a major problem in obtaining an acceptable plant balance is the apparent widespread belief that one belt scale type/model, is good for all applications.
For Example often single or dual weigh idler scales are in-correctly used on:
–> 350mm product Run-of- Mine (ROM) applications, or
–> High belt tension areas, or
–> Catenaries, etc;
We have solved many weighing problems over the years. One of our range of 14, Super Precision belt scales is bound to solve your weighing problems.
RTI’s major contribution
1. Easyweigh Belt Weigher
This model incorporates a low de_ection, rugged counter-balanced, single weigh idler, approach type weigh bridge with a single, precision load cell, operating in tension. The load sensor assembly incorporates overload protection and protection against mechanical shock. This model belt scale provides Rate and Total information on applications suited to Electro-mechanical Scales, where price is a major consideration. Being counter-balanced, the scale is suited to applications with lighter belt loadings. The Easyweigh® weigh bridge can be made to occupy the shortest linear space in the conveyor. This is important in applications where the available space is extremely limited, such as in weigh feeder type applications.
2. Accuweigh Conveyor Scale
This model incorporates a low de_ection, rugged, counter-balanced, four weigh idler, Approach/Retreat type weigh bridge design with a single, precision load cell, operating in tension, to provide superior weighing performance. The load sensor assembly incorporates overload protection and protection against mechanical shock.
–> Lighter belt loading applications (low bulk density materials).
–> Widely varying feed rate applications where a large dynamic operating range is essential.
–> For higher capacity applications at higher belt speeds.
–> Applications employing thicker belts.
–> Applications with steeper troughing angles.
–> Applications in higher belt tension areas.
–> Wide belts.
–> Superior performance requirements.
–> Where long-term high performance is essential.
–> Longer Maintenance Interval (MI) – time between calibration checks.
The performance of the tachometer or tacho, a component of the weightometer, which measures the speed of the conveyor belt, is fundamentally important for accurate results. Any errors in speed measurement will directly translate into errors in the Totalised tons and Tons per Hour output of the weigher.
4. Unipro IV Controller
The UniPro IV beltweigher controller with integrated HMI enables easy set-up, calibration and maintenance. The UniPro IV weighing transmitter has a wide range of digital and analog inputs and outputs.
5. Econoweigh Belt Scale
The Econoweigh beltscale is RTI’s low-end weigher. The weigher incorporates a low
deflection, approach type weigh frame with a single, precision load cell, operating in tension.The EC-1/2/4 Conveyor Scale provides Rate and Total information on applications suited to electro-mechanical scales, where price is a major consideration but where increased accuracy is required and where available mounting space is limited.
Since its inception, RTI has a strong focus on after market service. Many clients exclusively use RTI’s services for all brands of beltweighers on site including Process Automation (PA), Thermo Ramsey,Schenck, and Control Systems Technology (CST). RTI has full time beltscale technicians based out of Mackay, Queensland servicing the Bowen Basin, in Perth, and in the Pilbara region of WA.
