Re: Continuous Weighing On Slurry Lines
Dear Kobus,
There are at least two methods of weighing that could apply to your process. Both methods require that the material be in gravity flow at the point of weighing. The first is a gain-in-weight method with two tanks stacked, one above the other. The upper tank is mounted on loadcells. The second method involves measuring the redirection force of a free-falling stream of the slurry.
Comptrol Technologies Inc. manufactures equipment suitable for both types of applications. If you send me details of your process including the volumetric flow and the layout of the transfer system to indicate the best location for producing gravity flow, I would be pleased to send you a proposal.

Re: Continuous Weighing On Slurry Lines
After trying many different options, we have had good experience of using coriolis systems for mass flow measurement on our high solids slurry systems, this has become our norm for new plants.
I would suggest investigating this option for your duty. ■

Hello,
I am working for a company that mine and process phosphate. The process starts at an open pit mine, crushers, mills, floatation, filtration and drying. From the mills onwards, where water is added, it is a wet process. The slurry is pumped through lines up to 450 mm to the next stage.
We have magnetic flow meters + density meters installed on most lines, yet we battle with differences between so called "weighed" vs. "analytical" readings. The weighed figures come from the instrumentation and the analytic figures, are obtained from samples and lab results.
We are interested in investigating alternative options, such as continuous weighing systems. It would be possible to fit load cells onto the sumps / tanks. The density however varies and fluctuates between 1.2 and 1.8 kg/m3. Level measurement is also possible.
I will appreciate any suggestions and/or systems that we could investigate into.
Thank You

Dear Kobus,
I am please to see your name coming up again after many years.
I am confident the PT Ltd previously called Precision Transducers is able to assist you with our internationally recognized load cells.
Today we have just developed a completely new and revolutionary weighing module that I wish to introduce you to that will assist you in your weighing project for the sumps and tanks. This weighing module is just perfect for this type of weighing.
Please contact me direct on tony.thelning@pt.global.com
Kind regards

Continuous Slurry Weighing

You say you have discrepancies between "weighed" and "analytical" readings. Could I point out that from the details supplied, you appear not to be "weighing" the slurry at any point in the described process. If you were, most of your problems would disappear.
We could provide you with a complete solution if you can supply us with a few details such as flowrate and tank capacities.
I take it that the stated density should read 1.2 to 1.8 tonnes per m3.
