Bogaevsky Karyer LLP plans to supply the Russian construction market with 2 – 3 million m3 of sand, gravel, and stone annually.
At the start of 2015 the quarry site was at the geo-survey stage with the required quarrying equipment purchase still at the planning stage. However, Bogaevsky Karyer has been able to ramp-up full scale production using high-tech screening equipment.
The deposits at the quarry are estimated to be in the region of 48 million m3, and according to engineers this should be sufficient to support production operations, including plans for expansion, for around 10 – 12 years. The quarried materials require full-cycle processing and therefore, besides two-stage crushing, the production process includes washing and screening to obtain finished products in the form of crushed stone and gravel grades 5–20, 20 – 40 and 40 – 100 mm, plus quartz sand classes I and II.
In terms of ensuring final product quality, the backbone of Bogaevsky Karyer’s operation is two Sandvik QA451 triple deck screens supplied by Sandvik Construction’s authorised distributor Quarry-Service LLP. The QA451 is the largest in the Sandvik Construction range of mobile screens, which combines high throughput with high screening accuracy. A single QA451 unit is capable of grading up to 140 m3 of material per hour and up to 1500 m3 per shift. A two-man team operates the machines, with all operations staff having received advanced training in how to operate and service the units. This was undertaken during the machine commissioning, which was carried out by expert Quarry-Service personnel.
Alexander Shkuratov, Managing Director of Bogaevsky Karyer, said: "Our decision to choose the Sandvik QA451 was influenced by two factors: firstly we needed a screen capable of providing the maximum possible throughput in line with our future plans to increase production volumes. At the same time the equipment has to be rugged and reliable in order to withstand the heavy workloads – in our case the screens are running more or less around the clock. Secondly we wanted to be sure of getting high-quality and prompt after-sales support. The Quarry-Service specialists always arrive on time and there are no problems with consumables and parts availability, which means minimal equipment downtime.”
