Cement silo management made easy

Dec 21, 2005 · Before a silo is filled its level should always be re-checked. To avoid over-filling it is important to minimise the gap between shutting off the cement supply and filling the silo. Given that the bulk density of fresh cement varies between 1000g/m2 and 1350kg/m2, freshly aerated cement can reduce the capacity of a silo by over 25%.

Cement will be imported to the Site in tankers and transferred into one of two silos, which form part of the concrete batching plant, via a pneumatic hose.
