Once accumulated, overburden from the preparation of a quarry often occupy large areas, which then restrict the cultivation of the quarry itself. Moving these huge accumulations of waste material means moving - at great expense! - thousands of cubic metres of material.

A solution is installing an MB-S23 screening bucket with a 10 x 10cm grid basket on the excavator already working in the quarry - in this case a Hitachi Zaxis 460 LCH. In doing so, the customer obtained two types of material:

• material larger than 10 cm, which was retained in the basket, was directly loaded onto the dump truck and transported to the crushing plant to continue the process;
• the material smaller than 10 cm, on the other hand, was used for backfilling and embankment construction, thus avoiding additional costs for its disposal.

It turns unused materials into valuable resources, reducing transport and disposal costs. As did a company in southern Italy that had a major problem with stone waste. So it installed a bucket crusher on its JCB 4CX backhoe loader, obtaining saleable aggregate for subgrade paving.

Convert waste into profit! 

Valuable 'secondary aggregates' derived from demolition, reduces the use of traditional raw materials. Treated properly, they become valuable resources. This is what our customer did during the demolition of an old barn, where the steel inside the reinforced concrete was recovered and resold, while the secondary aggregate was used as road gravel. How? With a BF90.3 crusher bucket installed on the excavator that was already on site.
