BQ Quarries make it a Kleemann plant train treble
Mobile crushers and screens hit the spot for demanding granite-processing operation in Guyana
OPERATING in the Bartica region in Guyana, BK Quarries have successfully utilized three material-processing trains for their hugely demanding granite mining operation at Palmer’s Point and Teperu Itabu quarries.
The Kleemann PRO plant trains comprise a total of nine high-performance crushing and screening machines, which were distributed by regional Kleemann dealers Resansil. Each mobile plant train consists of a Mobicat MC 120 PRO jaw crusher, a Mobicone MCO 110 PRO secondary cone crusher, and a Mobiscreen MSC 953 EVO screening machine.
Since delivery, the PRO plant trains have impressed as the set-up of the crushing and screening equipment has seen the granite processed into different grain sizes, which are mainly used for Guyana’s infrastructure development.
The granite is fed into the jaw crusher with a feed size of 0–600 mm. The downstream cone crusher subsequently breaks up the material into pieces and feeds this to the screening plant, which produces three final products – 0–8 mm, 8–12 mm, and 12–19 mm.
Large grain sizes (19–45 mm) are fed back to the cone crusher via an oversize grain recirculation feature. Kleemann say this continuous recirculation ensures the best possible exploitation of raw material and the very best product quality.
‘The quality of the final product is decisive for us, and we achieve top quality with our Kleemann plants,’ commented Brian Tiwarie, managing director of BK Quarries. ‘We need extremely reliable technology where we are.
‘On the one hand, the very difficult accessibility is challenging, and on the other, the material we deal with here is demanding. The granites of Guyana are exceptionally hard and very abrasive. One of the outstanding features of these plant trains is the intelligent linking of the machines.’
Each machine works independently but sends signals to the upstream and downstream machines in the event of faults or overfilling. This automatic control ensures a smooth, disruption-free process.
Kleemann’s continuous feed system (CFS) also ensures each machine delivers optimum feed, which reduces wear and maximizes output. ‘Automatic control ensures that all machines are utilized evenly. This allows us to avoid any unwanted machine downtime,’ said Mr Tiwarie.
BK Quarries invested in their first Kleemann plant train back in 2021. The recommendations of other Kleemann customers in the region, as well as a visit to the German OEM’s plant in Göppingen, were instrumental in the company’s decision, not to mention the exceptional customer support from Resansil and Kleemann.
Since then, two more machine trains were added and installed in 2022 and 2023, respectively. All three Kleemann PRO plant trains are contributing to BK Quarries’ annual production target of 2 million tonnes of aggregates.
