CANADIAN TECHNOLOGY industry, the XL-Class provides the operation with high-capacity screening while maximising uptime and production. Combined with the grizzly technology, the XL-Class offers the necessary ability to remove large stones, relieving pressure on the primary crusher. Haver & Boecker Niagara also supplied six Niagara XL- Class vibrating screens to one potash customer for a 2 Mt / y plant. The operation uses mineral screening equipment in a combination of screen sizes to effectively process potash salts with 20 and 10 mm cut sizes, improving efficiency and producing high-quality potash fertiliser.
Haver screens are backed by a complete in-house manufactured screening media offering as well. Thompson:“ We fit our screening media to the application and we have our own design software with which we can check everything and ensure the customer is using the right combination of screen media – whether woven wire – Ty-Wire, rubber – Ty-Dura, polyurethane – Ty-Deck, or a hybrid. In some cases, a blend of media types can also be the right option. It is an art balancing the throughput needed with the wear resistance required.”
A recent development from Haver is the development of polyurethane media with two colours – dual-coloured – to show operators visually when the wear is at a critical level. An additional innovation widely used is a fast change out mechanism for Ty- Deck which uses pins.
In addition to screening, Haver is a leader in pelletising. Today’ s iron ore deposits with lower grades require intensive mineral processing where enrichment of iron components is achieved by separation of undesirable components. However, for this it is necessary to crush the ore to the de composition grain size and to supply sorting processes such as magnetic separation and flotation. To improve the process and product properties of the fine-grained iron ore concentrates, it is necessary to agglomerate these concentrates. Pelletising of iron ore concentrates in pelletising discs leads to significantly tighter distributed pellets with smooth surface.“ Machines like our SCARABAEUS ® 7500 pelletising discs are used for sustainable and efficient production of iron ore pellets. The unique design minimises circulation, increases productivity and profitability. These discs are remarkable for their significant tight particle size distribution with a target size of 10 to 14 mm, important for DRI processes.”
The powder feed material is formed into pellets with use of water as the liquid binding agent. The optimum operating parameters can be set by changing the inclination, the rotational speed, mass flow rate, and now also the rim height thanks to the innovative automatic pelletising disc control system.“ In addition, as it is adjustable and automatic, it is actually able to react to any changing nature of the ore coming in to still maintain the correct pellet output.”
A lot of existing Haver customers of its large pelletising discs are looking to upgrade to SCARABAEUS, but there is also a large market for greenfield sites.
As a screening and pelletising specialist, does that give Haver an advantage because of its focus, in contrast to other mineral processing giants that look to offer the entire range of solutions from crushing to milling to flotation, filtration and thickening?“ Absolutely, there are companies that can supply almost everything – and some of that they have developed themselves and some of it is through bolt on acquisitions. But for us screening and pelletising are in our DNA and one thing for example that distinguishes our screening expertise, is that we can really build anything that the customer might need. It’ s not simply engineering of equipment, it’ s understanding the entire mineral process and the role the screening circuit is playing within that.”
