Kleemann crushing & screening models paying off for Simcox Construction

Two Kleemann crushers and a Kleemann screening plant are working in quarries operated by New Zealand construction contractor Simcox Construction in the Marlborough region located at the top end of South Island.
“Everything is so much faster and there is far less downtime compared to our old machines,” said Antony Clark, general manager at Simcox Construction.
Processing greywacke for armourstone used in hydraulic engineering structures and for road construction, the three Kleemann plants – the MOBICAT MC 110 Z EVO jaw crusher, MOBICONE MCO 9 EVO cone crusher and MOBISCREEN MS 16 D screening plant – are the first of their kind in New Zealand.
Simcox produces two different products with its new Kleemann plant models. The first are blocks of rock with an edge length of more than 400mm which are used directly in hydraulic engineering. The second is used as base course material in road construction. For this product, the mineral material ranging in size from 0 to 400mm, is initially processed by being fed into the MC 110 Z EVO mobile jaw crusher. Pre-screening takes place using the independent double-deck pre-screen. The pre-screened material is transferred directly to the main discharge conveyor via the bypass. In the next screening stage, the material is conveyed from the MC 110 Z EVO jaw crusher to the MS 16 D screening plant, where material measuring -20mm is separated by screening and is discharged. Material measuring +20mm is fed into the MCO 9 EVO cone crusher for the next processing stage. In the second crushing stage, the MCO 9 EVO breaks the material down to 0 – 20mm. It is then returned to the screening plant for further screening in a closed cycle. The Increased productivity has led to the use of a larger excavator and an additional wheeled loader.
Once the decision to invest in Kleemann equipment had been made, Simcox wanted the plants to be commissioned as soon as possible. “Gary Payne from Wirtgen New Zealand put the wheels in motion,” said Clark, with the result that the crushing and screening plants were delivered within a few weeks. The general manager was also highly satisfied with commissioning: “Having the first machine on site right on time without disruptions to our schedules was crucial for us – and confirmed we had opted for the right partner.”
The plants’ performance was also impressive. “Our biggest benefits are greater efficiency and increased production,” concluded Clark.
