READYMIX CONCRETE202 CPI %u2013 Concrete Plant International %u2013 1 | 2026 www.cpi-worldwide.comThe Icelandic company Steypust%u00f6%u00f0in began operations back in 1947. Since then, the production of ready-mix concrete and precast concrete elements has been one of the main activities of the concrete plant. The company is constantly working on product development and the introduction of innovations in production. The company recently decided to invest in a residual concrete recycling system from the manufacturer Bibko%u00ae and has now put it into operation.The Bibko-ComTec 30 system supplied offers a recycling capacity of 30 m%u00b3/h and is additionally equipped with an external bucket elevator, which enables additional feeding of material at ground level. The washed-out residual concrete is either fed directly from the truck mixer into the charging hopper of the wash-out machine or fed by concrete pumps into the floor-level hopper of the bucket wheel.Solids > 0.2 mm are washed out and discharged accordingly in the wash-out trough. The water containing the smaller fines first flows through a water drain into a so-called pump sump, where it is then pumped into the agitator tank using a 2.0 kW pump. The tank, which was also supplied and installed by Bibko, is equipped with an agitator that keeps the fines in the residual water in motion by means of cyclic agitation, thus preventing them from settling.As the tank is above ground, a pump sump including a pump was installed in between. Due to the temperature and weather conditions in Iceland, this was fitted with cladding New residual concrete recycling system at Steypust%u00f6%u00f0in in IcelandBibko Recycling Technologies GmbH, 71717 Beilstein, GermanyThe Bibko-ComTec 30 system supplied offers a recycling capacity of 30 m%u00b3/h
