Conundrum Holdings & Alloys International Champion Industry Innovation

By on June 21, 2024

David Camilleri, Alloys International Australasia: When I first joined the company in 2016, one of my earliest rolls as Sales Engineer was to further expand our presence within the Quarrying and Mining industry. My advice was that we had good sales of our Chrome Carbide Overlay Wear Plate (AbrasaPlate®), but there were many unexplored opportunities. AbrasaPlate® was a good product for me to enter the market and further build and expand on customer relationships.

I came across Conundrum Holdings in a simple Google search and contacted Charles Kerr at their Epping Quarry. Charles suggested a trial at the Stawell Quarry as the rock there was much more aggressive, and any results would be attained in a short period of time.

The opportunity offered was to go up against the highest wearing plate in the quarry, being the circulating discharge impact plate. The 1m discharge combined with 135mm minus Hornfels rock at a rate of 400 -600 tons/hour has been the challenge for all plates trialled in the past. Challenge Accepted! In May 2016, Heavy-Duty Cross Hatch AbrasaPlate® 9 on 10 with dimensions 570mm x 750mm was installed directly beside the existing plate.

In summary the result, with 1 million ton achieved over each four indexes, The AbrasaPlate® Cross Hatch far exceeded expectation and was noted to be the best plate Conundrum has come across since established in 1988.

The decision was made to line the chute with our Cross Hatch AbrasaPlate®, though because the wear life was exceptional, it was lined with a thinner version 6/8 to lower the weight on that area.

Well, I have to say that was a huge confidence boost for myself, and the Cross Hatch AbrasaPlate® has since been my go-to for any Quarry/Mine approached from there forth.

On the back of that success, we at Alloys International have continued to expand applications within the Conundrum Group, supplying AbrasaPlate for the lining of screens, chutes, crusher, buckets along with maintenance welding consumables such as hard facing and low hydrogen.

In October 2021, Charles contacted me, advising one of the Cone Crushers require new wall liners and would like to apply the Cross Hatch AbrasaPlate for maximin wear life against Rock Hornfels 100 – 50mm, 200,000 ton/pa.

The AbrasaPlate 9/10 Cross Hatch Liners were firstly reversed engineered by our engineering team. With our DXF drawing, they were cut, rolled, and installed in Nov 2021.

The Cross Hatch wall liners were inspected in April 2024. In the high wear zone of the crusher, we found minimal wear within the Cross Hatch weld overlay and had yet to recede into the solid 9mm chrome carbide. At this rate, our expectation for this application is to achieve 15 years. Another pleasing result.
