SlurrySucker allows easier removal of silt and sediment

Integrated Pump Rental has proactively addressed the need for easier removal of silt and built-up sediments from process water ponds, return water ponds and other water storage areas. The introduction of the SlurrySucker dredge units into the company’s short- and long-term hire fleet will assist mines in on-going maintenance. “Severely silted up ponds and reservoirs can impact on the water storage capabili- ties of a mine or plant, negatively affecting downstreamprocesses. Designed and engi- neered locally by Integrated Pump Rental, the SlurrySucker dredge unit is capable of extracting high tonnages due to the design

slurry is required, or Grindex slurry pumps where there is a need to remove slurry from ponds or dams. “The biggest advantage of this new dredging unit is that the pumps can be changed to accommodate specific cus- tomer applications. An example of this would be where the customer needs to remove 160 dry tons per hour. In this instance, the dredging unit would be cus- tom engineered to handle the required flow,” says Vine. “The SlurrySucker dredge unit can be used on plastic lined dams without any damage to liners. This is very important from an environmental perspective as there is no risk of the liner being cut and water leaking out,”Vine adds. Galvanised steel is used for the con- struction of the dredging unit framework and for use in highly corrosive applications it can be fabricated from stainless steel. Engineered as a robust, compact dredging unit, the SlurrySucker can be easily trans- ported on a standard road trailer, making it simple to move from pond to pond on a mine site.

A number of Pilot Crushtec Interna­ tional’s customers have discovered that TowerLights can be used to render an addi- tional service. Many site offices utilise its generators not only for lighting but also to power computers, air conditioners and refrigerators, a real boon when operating in remote areas. Scherf reports that sales have grown by 30 % year on year since the range was launched locally in 2012. The TowerLight range currently extends to six products. Top of the range is the VT8000-FH, which is capable of hoisting four 2 000 W metal halide floodlights to a height of 9 m. It is equipped with a fully hydraulic lifting system for legs, mast and lamp adjustments and is certified stable at wind speeds of up to 110 km/h. A single unit is capable of illuminating an area of 24 500 m². Equipped with a rotating beacon light, this product is purpose built to suit the needs of opencast mining operations.

and engineering of the dredge head,” says Lee Vine, GM at Integrated Pump Rental. During the developmental stages, Integrated Pump Technology made use of computational fluid dynamics (CFD) to optimise and validate the design. This pro- vides customers with the assurance that the performance of the SlurrySucker and its engineering integrity are maximised. Vine says that two standard units are available. The smaller or SlurrySucker Mini is capable of extracting 120 m 3 per hour of slurry/water mixture, equating to 30 to 40 dry tons per hour. Double this extraction volume can be achieved with the SlurrySucker Maxi, which will remove between 70 to 80 dry tons per hour. The SlurrySucker Mini has a 100 mm discharge and the SlurrySucker Maxi has a 150 mm discharge. Manufactured using locally pro- duced components, the SlurrySucker dredge units incorporate pumps from the respected Grindex slurry and dewater- ing range. Selection of the pump will be determined by the dredging operation at hand and could include either Grindex dewatering pumps where agitation of the “When we originally introduced the range, our intention was to help our cus- tomers grow their businesses by making it possible for them to work around the clock. In industries like mining, where the critical denominator is cost per tonne, the extra hours gained give users a significant competitive advantage. However, with the current irregularity in power supply, these products have become indispensable to the sustainable operation of their businesses.” Scherf explains that operators in the mining and construction industries had traditionally been opposed to working two or three-shift operations owing to concerns over the physical safety of their employees as well as potential damage to essential and costly equipment. However, these barriers have been removed. “When lighting of this intensity is avail- able, it immediately removes another major concern around the operational health of equipment. Under darkness it is very the right product at the right time,”explains Pilot Crushtec International CEO Sandro Scherf.

The SlurrySucker dredge unit is capable of extracting high tonnages due to the design and engineering of the dredge head.

Lighting tower sales show robust growth The range of TowerLight lighting towers produced in Italy by Generac Towerlights, the world’s largest producer of lighting towers, and imported by local crushing and screening specialist Pilot Crushtec International, provides powerful lighting solutions for commerce and industry.

TowerLight systems contain on-board diesel generators that produce sufficient electricity to power a battery of four or more metal halide flood lights mounted on telescopic towers. The telescopic tower mast completely eliminates the safety hazards associated with scissor-type masts. Depending on the model, these telescopic masts are either hydraulically elevated or elevated by means of a hand winch. They are easily transportable and have the option to be fit- ted to a locally manufactured trailer to be towed on public roads, allowing operators to react rapidly to power outages when and where they occur. “The introduction of the range has proven to be a far-sighted marketing deci- sion appearing as a classic case of having
