Sandvik ticks all the boxes for Danoher Contracting
Pilot Crushtec International’s claim that its business is not about selling products but providing workable solutions was put to the test with the recent delivery of a Sandvik UJ440i heavy duty mobile jaw crusher to South African crushing specialist Danoher Contracting.
The customer was in urgent need of a high capacity machine for use on a Haw and Inglis site on the N10 between Cradock and Cookhouse. A SANRAL project, it involves the upgrading of 40 kilometres of degenerated road and Haw and Inglis subcontracted a substantial portion of the crushing component, namely the supply of 160 000 tonnes of sub-base material, to Danoher Contracting.
According to national sales manager Nicolan Govender, every effort was made to ensure that the R8.3 million machine was up and running reliably in the minimum possible time.
“The Sandvik UJ440i docked in Durban on Tuesday the 12th of March arriving on site on Saturday the 16th of March accompanied by installation manager Kobus Joubert and Sandvik product manager Peter Delbrant from Sweden. The entire installation and commissioning process ran without a hitch and by that afternoon the crusher was fully operational,” says Govender.
Since its arrival, the Sandvik UJ440i has been consistently crushing blasted dolerite with a maximum feed size of around 500mm. The crushed material is fed from the Sandvik into a cone crusher supplied by another manufacturer and the two units are working well together in tandem, producing 250 tonnes per hour (tph) around the clock. Govender, however, is convinced that output could reach the 300tph mark with the availability of a higher capacity screen.
“The ability of these two pieces of equipment to work efficiently together is due to their ability to communicate using a downstream cable connection. When the secondary crusher senses an overload, this is signalled to the Sandvik and the feed rate is immediately halted or reduced,” he says.
Not only is it intelligent in operation, it is decidedly frugal. The Sandvik UJ440i is powered by Volvo’s low revving D 13 Stage 3b diesel engine, delivering 315kW of power directly to the jaw crusher via vee belts.
“The average fuel consumption recorded on site after nearly two months of continuous operation is 31.8 litres per hour, an astonishing performance for a machine of this size and production capacity,” says Govender.
Danoher Contracting’s Neil Danoher is well regarded in the crushing and screening industry and is suitably qualified to cast an expert opinion on his company’s latest acquisition.
“We are very happy with its performance and economy. It is crushing a difficult material and meeting our production targets. In short, it is handling the job well.”
The crusher is expected to remain on site for another 6 to 8 weeks, before being employed in a future contract in Botswana.
Danoher says that the Sandvik purchase was by no means a spur of the moment decision and that the company had carefully weighed up its options before selecting Sandvik.
“Our main consideration was who we were dealing with. We wanted a supplier that could lend a sympathetic ear and has the necessary knowledge and skills to solve operational problems. Pilot Crushtec International has these credentials and it now has a heavy duty range to meet our needs,” he adds.
Subsequent to its experience with the Sandvik UJ440i jaw crusher, Danoher Contracting has placed orders for a Sandvik UH440i mobile heavy duty cone crusher and a Sandvik QE440 mobile heavy duty scalper for use on other projects going forward.
