3Q Concrete Holdings successfully commissioned their new plant in Middelburg. As an industry leader 3Q took the initiative to upgrade their plant located in the industrial area.

The process started 4 weeks ago with the demolition of the old plant. The old silos, as well as the overhead bin system was removed in its entirety. The system was messy and inefficient and did not conform to modern technological advances.

The new plant consists out of 2 new silos. One for Cement powder and one for fly ash. The overhead bin systems was replaced with a hopper bin. This whole system allows for more efficiency in the batching process as a whole. As all the Cementitious material, aggregates, admixtures and water are weighed during the process, it allows for total accuracy. Batching speed and capacity was also increased, and this plant can now produce up to 60m3 of concrete per hour.

To ensure that 3Q also conform to Safety, Health and environmental standards it was decided to introduce measures that proof our commitment to Greener practices.

On top of the cement and fly ash silo’s 3Q fitted Silo Venting Filters. The filter is a cylindrically shaped dust collector for venting of pneumatically filled silos. The stainless steel body contains vertically mounted filter elements. The air jet cleaning system is integrated in the weather protection cover.

Dust separated from the air flow by the special filter elements drops back into the silo after an integrated automatic reverse air jet cleaning systems has removed it from the filters.

This filter systems ensures that no dust from the cement powder or the fly ash is released in the air when topping up the silos. This contributes to lowering the air pollution and reducing the carbon footprint.

Another addition to the new plant is the recycling of water. Waste water from the batching process is recycled and used to spray onto the course aggregate. This cools the aggregate but more importantly is the dust containment.

The “Going Green Concept” forms part of 3Q’s strategy to be a leading and preferred supplier of ready mix concrete within the 3Q footprint.
