Three Kleemann plant trains are working deep in the Guyanan jungle.
The massive plants from Kleemann were transported along the Mazaruni River to two quarries in the deepest interior of Guyana. Here, three PRO plant trains from Kleemann process granite.
Machines must work efficiently and reliably in a jungle region that is extremely difficult to reach by water or air. Therefore, three plant trains were brought step-by-step to the Bartica region in Guyana. The work site’s difficult accessibility and the hard, highly abrasive granite pose particular challenges.
Powerful machines for hard conditions
The three plant trains each consist of a powerful mobile jaw crusher, MOBICAT MC 120 PRO, a mobile cone crusher, MOBICONE 110 PRO, and a classifying screen, MOBISCREEN MSC 953 EVO. The plants process the rock into various grain sizes, primarily used to expand Guyana’s infrastructure.
The granite loaded onto the jaw crusher is 0 to 600 mm in size. The downstream cone crusher breaks the material into shape and feeds it to the screening plant, which outputs three classified final products: 0-8 mm, 8-12 mm, and 12-19 mm. Larger grain sizes (19-45 mm) are fed back into the cone crusher via the oversize grain returning system. This continuous recirculation ensures that the raw material is fully utilised and that the product quality is very good.
One advantage of these plant trains is the intelligent linkage of the machines. Each machine works independently and sends signals to the upstream and downstream machines in the event of malfunctions or overfilling. This automatic control enables a trouble-free process. The Continuous Feed System ensures that each machine is loaded in a manner that reduces wear and maximises the output. “The automatic control system ensures that all nine machines are evenly utilised. We basically have no unwanted machine downtime”, reports Brian Tiwarie, Managing Director of the BK Group. “Furthermore, the quality of the final product is of decisive importance to us, and the Kleemann plants allow us to achieve top quality.”
The BK Group decided three years ago to acquire the first plant train from Kleemann. Before deciding, they spoke to other companies about their experiences and visited the Kleemann plant in Göppingen. Further plant trains were installed with the aim to produce two million tons of aggregates per year.
The company is very satisfied with the product quality and low fuel consumption. ”At this location, where everything really has to be transported by water in a time-consuming manner, high fuel requirements and the transportation of procured spare parts result in additional costs. With regard to these two aspects, we are very satisfied with the Kleemann plants”, says the Managing Director. Kleemann and the regional Wirtgen Group dealer Resansil provide support and reliable service despite the accessibility difficulty.
