A more efficient use of materials
With this system less material is needed to be send out for external analysis. This provides a mayor saving in material costs.
The system simplifies the preparation process in a way that the amount of samples can be increased resulting in a quality improved of the production process.
Incorrect taken samples or samples processed in an incorrect way will lead to false analyses, resulting in goods being approved (false positive) or declined (false negative) wrongly.
Outsourcing this process creates many expenses, just think about the amounts of product that are lost during the process.
What does it do
To determine the qualities of the Ferroalloys the pieces of alloy (60-70 mm) are sampled and then reduced. The steel company used to reduce the 25 kg of materials using a jaw crusher (reduction down to 10 mm).
After the primary crushing the operator needed to grab the material from underneath the machine and put it in a rolls crusher. Here the product was further reduced to grit (2mm). The sample was send over to an external laboratory for analyses.
This installation has simplified the size reduction process for this steel company to a mere push of a button. Now since there is no more need for the operator to lift any heavy materials or perform multiple actions the process is more efficient, resulting in more samples and an overall higher quality.
How it works
The operator puts 25 kilograms of material in the inlet funnel and starts the process at the central control box. A vibratory feeder underneath the inlet funnel evenly feeds the bucket elevator. The bucket elevator lifts the material and feeds the jaw crusher (type LMFC250) which reduces the material to 2mm.
The grit material goes, using a flexible connection, to a rotary sample divider which divides the sample in ten equal parts of 2,5 kilograms (sub samples). The alloys have a density between 3 and 8 kg/liter, giving a partial sample volume of 500 to 800 ml.
This sample will be pulverised in a ring mill (type LM2000) to reach the desired end finesses of 125 micron. The external lab needs 12 to 15 grams of this product to make it into a tablet that can be analysed with an XRF-machine (X-ray fluorescence).
Application Examples: Chrome, Nickel, Titanium and Molybdenum, Iron, and many more materials.
