Stroytekhservis Cherepovets is a quarry company in the west of Vologda Oblast, Russia, established in 2005 and specialising in the production, sales and transportation of sand and aggregates. The company has purchased a new M2500 washing plant from CDE which is significantly reducing clay and dust contamination and producing a range of washed sand and aggregates.

The new plant was delivered by CDE in conjunction with Mining Technologies, CDE’s sales partner in Russia. 

Stroytekhservis Cherepovets is part of the Stroytekhservis group of companies. The organisation is rapidly developing with divisions in construction, sand and aggregate production, concrete production and equipment rental. Stroytekhservis owns three quarries in the Cherepovets region as well as crushing and screening plants in the area and a concrete production facility.

The company’s main focus is the supply of bulk aggregates and building materials for both clients and also in their own projects. The Stroytekhservis Group aims to expand its construction division over the next few years to provide a turnkey service for its customers by delivering a complete solution for commercial and residential projects.

Stroytekhservis Cherepovets approached CDE’s Russian partner, Mining Technologies, in September 2012 and presented a natural sand and gravel material containing over 8% clay content which had to be cleaned. Stroytekhservis required a 120tph plant that would produce 4 washed and sized products; a 0-3mm building sand, a 3-5mm concrete sand, a 5-25mm aggregate and a +25mm aggregate. The raw material is 0-40mm sand and gravel. Stroytekhservis also required a water treatment system as they had limited space to accommodate settling ponds and additionally they wanted to reduce the requirement for fresh water to feed the plant. 

After a thorough sieve analysis at the quarry, the equipment specified to process the material was a M2500 washing plant and an AquaCycle thickener. Mining Technologies invited representatives from Stroytekhservis to visit a nearby CDE installation in Priozersk in the Leningradsky region. This visit demonstrated how the M2500 and AquaCycle combination could be used successfully in the processing of material with clay and dust contamination.

“We were impressed by the capability of the M2500 and AquaCycle to produce high quality sand and aggregates and realised how the system could be applied at our Cherepovets quarry. We were confident that the CDE washing solution would meet our needs” explains Kalashnikov Vitaly, CEO of Stroytekhservis Cherepovets.

CDE specified a M2500 to tackle the problem of clay and dust contamination. The M2500 ensures that the clay material is being effectively processed to create 4 commercial grade sand and aggregate products. The requirements for concrete sand are defined by the Russian state standard GOST 8736-93. “It was very important that the final sand product should meet the standard specification for concrete production. The M2500 produces in specification products which comply with this standard and therefore are suitable for construction works as clay and dust particles in the final product are 0.2%” explains Vitaly Vizir, CEO Deputy for sales for Mining Technologies.

The plant also includes an AquaCycle thickener which was selected for its recycling benefits as it significantly reduces the volume of fresh water required as up to 90% of the water used in the washing plant is re-circulated around the plant.
