<\/a>\u201cCustom engineered chutes and transfer points have been shown to facilitate smoother flow of mined material, with greater reliability and uptime for a more streamlined and productive operation,\u201d explains Nienaber. \u201cThe initial focus when providing transfer point solutions to a brownfields project is usually to take careful note of the physical layout so that chutes are designed with spatial constraints in mind.\u201d<\/p>\n\n\n\n
This can be most accurately and efficiently achieved using 3D laser scanning of the existing layout, to rapidly gather detailed measurements of large infrastructure on a customer\u2019s site. Using this data, a precise 3D model can be generated on the basis of which the necessary chutes and componentry can be designed and manufactured.<\/p>\n\n\n\n
\u201cThis aligns well with Weba Chute Systems\u2019 considerable in-house expertise in chute design, as each chute we build is unique to the application it serves,\u201d Nienaber says. \u201cIt is important to remember that every transfer point exists in a relationship to other equipment, such as a screen, crusher or conveyor belt.\u201d<\/p>\n\n\n\n He highlights that an understanding of this relationship will underpin the productive application of transfer point design and installation. Indeed, while the 3D scanning and modelling technology provides a valuable starting point for design there is also scope for added improvements in the plant layout.<\/p>\n\n\n\n \u201cOn so many of the sites that we visit and assess, we can soon identify where changes in the relationship between the transfer points and other equipment can deliver better results,\u201d says Nienaber. \u201cWhile it is sometimes difficult \u2013 even costly \u2013 to implement some of these changes, the customer reaps many times the value in terms of uninterrupted volume flow, uptime and productivity.\u201d<\/p>\n\n\n\n The first prize when installing transfer points, he emphasises, is always the optimal solution \u2013 which may mean reconsidering the position of the upstream and downstream equipment. In fact, this is always the starting point for Weba Chute Systems\u2019 transfer point solutions: to achieve the most productive result for the customer.<\/p>\n\n\n\n \u201cWith our engineered design approach, we always consider the context of where our chutes are going to operate, and our decades of field experience allow us to advise the customer what will work best,\u201d he says. \u201cWe might advise on how adjusting the position of a conveyor\u2019s head pulley, for instance, would improve chute performance and overall plant efficiency.\u201d<\/p>\n\n\n\n He notes that, while certain configuration changes might exceed budget constraints, the company\u2019s intervention often allows for positive modifications to be made. A recent example of this was in a contract for a South African iron ore producer in the Northern Cape. Weba Chute Systems was asked to address the mine\u2019s challenge where an existing competitor\u2019s chute needed attention every two days which was severely hampering production.<\/p>\n\n\n\n \u201cWe designed and installed the optimal customised chute, but also recommended some related adjustments,\u201d he says. \u201cThe design was a split chute, and the plant needed to speed up its conveyor quite considerably \u2013 as well as lifting the head pulley slightly \u2013 to achieve the necessary results.\u201d<\/p>\n\n\n\n The changes recommended had financial implications, so the customer required considerable certainty that the solution would be successful. To underpin its plan, Weba Chute Systems digitally modelled the proposed design and simulated its operation using software that visualised the movement of material through the chute.<\/p>\n\n\n\n \u201cUsed by our skilled designers, this powerful software delivers more than a pretty picture,\u201d emphasises Nienaber. \u201cThe simulation presents in video format exactly how equipment will be positioned and how material will flow through the system.\u201d<\/p>\n\n\n\n Fundamental to these kinds of solutions, of course, is a close collaboration with the customer, built on a high level of trust in the company\u2019s past performance. Aligned to this is Weba Chute Systems\u2019 commitment to see through any project it embarks upon, he says.<\/p>\n\n\n\n \u201cOur customers know we never walk away from a project \u2013 and this is an important factor in brownfields projects where one is often working within existing constraints rather than a clean slate,\u201d he argues. \u201cWe have confidence in our people and our designs, and remain accountable for any solution we provide until it performs to levels we have promised.\u201d<\/p>\n\n\n\n Another important factor in many projects is the level of degradation of mined material, which the company prides itself on reducing through its scientific, streamlined approach to the dynamics of bulk materials handling.<\/p>\n\n\n\n \u201cAn example of where this was important was a steel plant in Turkey where we installed a number of our chutes,\u201d he explains. \u201cThe customer required minimal ore degradation, and even monitors the ore passing through each chute to ensure fines generation is kept to a minimum.\u201d<\/p>\n\n\n\n Weba Chute Systems was required to incorporate samplers in its installations in this plant, and these samplers generate the data to verify the chutes are performing to expectation. The company\u2019s custom design allows greater control over the direction, flow and velocity of material, whose volume and characteristics are specific to each application.<\/p>\n","protected":false},"excerpt":{"rendered":" As mining companies embark on brownfields initiatives to meet rising market demand for battery and other minerals, the optimising of transfer points presents a valuable opportunity to deliver more output cost effectively.
