Three PRO plant trains in granite
Three high-performance plant trains at work deep in the Guyanese jungle
The journey alone was spectacular: The massive Kleemann Kleemann plants crossed the Mazaruni River to reach two BK Quarries work sites in the depths of Guyana. The customer counts on three PRO plant trains from Kleemann for its granite mining operations.
In a jungle region that can only be reached with great effort by water or air, machines have to work with exceptional efficiency and reliability. The BK Quarries, company, which operates two quarries in the Bartica region of Guyana, didn’t choose its new equipment lightly. It was a major acquisition: Three plant trains were purchased successively – a total of nine high-performance machines. “We need extremely reliable technology out here,” explains Brian Tiwarie, the company’s Managing Director. “On the one hand, the very difficult accessibility is challenging, and on the other, the material we deal with here is also demanding. The granites of Guyana are exceptionally hard and very abrasive.”
High-performance machines for heavy-duty conditions
BK Quarries currently uses three plant trains. Each train consists of a powerful mobile jaw crusher MOBICAT MC 120 PRO, the mobile cone crusher MOBICONE MCO 110 PRO and the classifying screening plant MOBISCREEN MSC 953 EVO. The crusher plants process the rock into different grain sizes, which are mainly used for the development of infrastructure in Guyana.
The granite is fed into the jaw crusher with a feed size of 0 to 600 mm. The downstream cone crusher breaks up the material into pieces and feeds it to the screening plant, which then outputs three classified 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 the oversize grain recirculation. This continuous recirculation ensures the best possible exploitation of the 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,” says Brian Tiwarie happily.

Efficient and intelligent production process
“One of the outstanding features of these plant trains is the intelligent linking of the machines,” reports Brian Tiwarie. Each machine works independently but sends signals to the upstream and downstream machines in the event of faults or overfilling. This automatic control guarantees a smooth, disruption-free process. Kleemann’s Continuous Feed System (CFS) ensures that each machine is provided with an optimum feed, which reduces wear and maximises output. “Automatic control ensures that all machines are utilised evenly. And this allows us to avoid any unwanted machine downtime,” sums up Brian Tiwarie.
Experience and reliability impress
The BK Group decided on its first Kleemann plant train back in 2021. The recommendations of other Kleemann customers in the region, as well as a visit to the Kleemann plant in Göppingen, were instrumental in the decision. The excellent support provided by the regional dealer Resansil and Kleemann ultimately tipped the scales. Since then, two more machine trains were added and installed in 2022 and 2023. One in the same quarry and the other at a different location. The target: production of 2 million tons of aggregates per year.
The company is very pleased with the excellent product quality and low fuel consumption. “At this site, where everything has to be transported over water at great expense, high fuel consumption and procuring spare parts for the transport can cause considerable additional costs. “We are very satisfied with the Kleemann plants on these two counts as well,” reports the Managing Director. The team from BK Quarries is happy to have found a partner with Kleemann and Resansil on site who can also guarantee reliable service under such tough conditions.
Ideally prepared for the future
With the expansion of the oil and gas industry in Guyana, the demand for high-quality building products is also growing – and this promises secure growth for BK Quarries. The company also has another project it is very passionate about: Part of the BK quarry will be transformed into an exclusive tourist retreat. A large guest house has already been built on the site, and in 2011 it hosted the heads of government of the Caribbean Community (CARICOM). The site is located in the midst of magnificent, towering trees, very close to a spectacular waterfall.
