The goal is to develop a virtual belt scale for continuous weight measurement of bulk mineral material during transport on a belt conveyor. The system is illustrated in Fig. 1. The belt conveyor moves at a constant speed and has to overcome a fixed height h. The belt is driven by an electric motor whose
Belt scales continuously and automatically weigh the material conveyed during regular transport on the belt conveyor – and that with high accuracy. Single-idler belt scales have measurement errors of 1 to 2 %. Multi-idler belt scales reach even higher accuracies of <1 % and are also approved for applications subject to calibration (Fig. 1).
The chart is a graphical representation of the formula : Where, p = kgW (L + 10H) p = the correct number of plies. k = a constant, depending on the type of drive. g = the weight in pounds per cubic foot of material handled. W = the width of the belt in inches. L = the length of the belt in feet (approximately twice the center distance).

So belt scales present a low-cost and reliable solution for monitoring material streams in lime processing. The use of belt scales is possible in almost all belt conveyors. For this, MTS offers numerous variations as single-idler or multi-idler belt scales for stable and precise weighing over the long term – also in a legal-for-trade version.
For SAG mills (particle 150 mm) you would have to take a few meters length and it becoming quite an exercise (say you have 4-8 x 45 gallon drums you need to weigh accurately). If trucks or loaderite is more accurate that your belt scale then problem is with your belt scale, conveyor, operations or combination of.

NTEP APPROVED BELT SCALES. Models NAR 4 and 6 idler NTEP Approved Belt Scales are designed for applications on conveyor belts of 18 to 96 inches wide, operating at belt speeds between 100 and 1000 ft/min, under loading of 34 to 340 lb/ft, at flow rates of 102 to 10,200 T/hr. The Model NAR family uses the same "graded …
The goal is to develop "virtual" belt scale that is able to replace conventional expensive built-in belt scale systems. Possible application of this solution include e.g. …
The belt scale is the most common online bulk material massflow sensor used in the mineral-processing. The belt scale provides an accurate online mass-flow measurement from the process if calibrated properly. However, the high price of the sensor prevents the installation of multiple belt scales in a single mineral-processing plant.
Flexicon Corporation is a world leader in the design and manufacture of bulk handling equipment and custom-engineered and integrated plant-wide systems that transport, discharge, fill, weigh, blend, deliver and/or feed a broad range of powder and bulk solid materials. Flexicon products range from individual equipment to automated systems that ...
In this paper, non-contact weigh scale measurement system based on gamma radiation technique was proposed and implemented. This measurement method consists of gamma ray source 50 mCi, scintillation detector and signal processing. This scales system to weigh the coal transferred from barge to coal bunker Suralaya power plant using belt …
Maximize bulk weighing and monitoring efficiencies with service and support. Bulk material handling systems keep processes moving, whether you're conveying ore or aggregate, cement, coal, chemicals, or cereal. A vast array of these commodities are moved 24/7 by bulk conveyors in mines, electric utilities, and processing plants across the ...
Weigh boxes as they flow through your conveyor line to reduce bending and lifting. These scales integrate seamlessly into your line thanks to their conveyor rollers or ball transfers, which move boxes along after weighing. A check-weighing mode flags boxes that are outside a specified weight range. And a weight accumulation mode keeps a running …
For weighing and totalizing continuous flow rates of sand, gravel, crushed rock, or some other bulk material up to 15,000 tons per hour, the Schenck Process …

Belt conveyor scales provide a means of weighing bulk materials while in motion. The obvious advantage over static weight systems is that the flow of material needs not be interrupted. As in batch weighing, accurate sensing of the weight of material is required. …
The scale uses a container that allows a volume of exactly 1000 ml. After collecting the sample, the container is hung on a weight scale which measures in grams. The printed scale reads the pulp density directly in grams/ 1ml. Since water density is 1.0 gm/ml, the scale also indicates the specific gravity of the pulp.
