Wear protection systems for self-unloading vessels

Wear protection systems for self-unloading vessels Wear resistant specialists were approached by a global shipment management service provider, responsible for fleet and gravity type self-unloading vessels to provide a solution which would help reduce material build up, increase material flow and promote an easier cleaning regime along with an effective wear protection system. Kingfisher were approached by the global provider whose self-unloaders are expected to operate 24 hours without the need for stevedores or trimming crews, as this speeds up cargo handling, and further reduces port and demurrage costs.

These types of vessels are capable of handling material up to 20,000 metric tons per hour, therefore effective equipment and continual process performance is a must. The companies Technical Superintendent stated “Our core business is the shipment of iron ore, as the material is transported from “A” to “B”, material is affected by a number of factors which contaminate the material and increase the moisture content within the ore, leaving the material lumpy and exceedingly sticky, which then builds-up on top of the A-frame inside the cargo hold. The process of transporting material from “A” to “B” then becomes more difficult as it becomes extensively hard for it to be transported from one point to another without it sticking or building up within the unloading and loading points likewise the lumpy material tends to cause considerable wear and abrasion within the pocket conveyor discharge chute. Project manager Mark Bond commented “Handling sticky iron ore is always a challenge for bulk material handlers as material characteristics can be extremely unpredictable especially where environmental factors are concerned. During such circumstances, end users do not have many options available, therefore maintenance engineers are then required to add in measures to help protect their systems and contribute to the on-going process and product output. Technical superintendent added “We approached Kingfisher as we required a solution which would reduce the material

During such circumstances, end users do not have many options available, therefore maintenance engineers are then required to add in measures to help protect their systems and contribute to the on-going process and product output. Technical superintendent added “We approached Kingfisher as we required a solution which would reduce the material hang-ups within the cargo holds and ease the cleaning process within the pocket elevator feed chute, as it is very important for us to keep our equipment material free and likewise eliminate the extra resources required to strip the cargo holds or implement additional cleaning regimes within the cargo holds and conveyor chute” After reviewing the issues, material flow and quantities, Kingfisher recommended to install a combination of wear resistant lining systems. Kingfisher K-PLAS material was to be installed top of the A frame, as the polymer material promotes material flow, its smooth surface will allow material to slide down the system without causing material to “hang up” on top of the A-frame, along with Kingfisher K-ALOX lining system 50mm and 25mm thick 92P ceramic liners to offer protection to the main wear areas of the conveyor chute. The installation procedure involved cleaning and preparing the surfaces of the cargo holds, before our K-PLAS liners were installed stated Mark Bond, our aim is to offer the customer with a service which fits in with their requirements as Kingfisher’s service provision comprises of full design, manufacture, surface protection and installation service. Operations Director Graham Bailey commented, “Since the installation in July 2014, the customer has been reviewing the process and has confirmed the project has been a success. The results have been touchable, the hang-ups on top of the A-frame are now reduced to a minimum quantity and the pocket elevator feed chute now has less material build-up, resulting in fewer wear areas”
