RE:How about this thenAt what capacity was the sorter testing done for the steinart and tomra? The machine they ordered is a 40 tph machine. The machines are used for various products and can handle that volume (conveyor speed) depending on what they are sorting for, but the question is, what volume per hour did they run them at to get the recuperation they reported for their gold samples? The machine ordered is a Tomra machine. Last year, Novo reported the following stats regarding the Steinert machine traveling at 2.8m /sec, with various tonnes per hour of ore processed.
Presumably, the 2020 Tomra technology machine produces increased sorting speed.
https://www.novoresources.com/news-media/news/display/index.php?content_id=367 Steinert has provided favorable initial guidance on expected productivities of sorting various size fractions of gold-bearing material utilizing mechanical sorters. Productivity estimates include: - Particle sizes 17-50 mm: approximately 280 tonnes per hour
- Particle sizes 6-17 mm: approximately 90 tonnes per hour
- Finer particle sizes including sub-mm: approximately 50 tonnes per hour
Numbers above are estimated based on sorting a loosely packed mono-layer of material scattered across 70% of a 2 m wide conveyor belt moving at a speed of 2.8 m/sec. Sorting of fine material may benefit from use of thinner belts, 3 mm instead of 5 mm, which allows for a higher induction signal and is expected to further reduce the size of gold particles that can be detected.
