Haarup supplies day bins, ground bins, in-line bins and silos.
Haarup's different types of bins and silos each have their advantages depending on the infrastructure of the concrete plant and the capacity needed.
In-line bins are used in larger plants and have the advantage of a large storage capacity and relatively low height. The bins can be installed in new as well as existing buildings or can make up an independent building structure with their own mixer platform. This makes it possible to design a very compact plant with a low building height. In-line bins are either supplied as round bins or grouped, rectangular bins and in principle, there is no limit to the number of bins.
Haarup manufactures aggregate bins with square silos and central outlets which offer a series of advantages when compared to round silo systems because of the optimal use of space. The centered outlet ensures minimal wear and tear on the silo walls. Fitting side covering on a square structure is much simpler. Aggregate bins are used where little space is available but where large capacity and high speed is required. This type of setup is well suited for plants producing ready-mix concrete.
Ground bins make visual checks of the bin contents possible and do not require investment in a filling system. Bins are filled directly by rear or side tippers. Ground bins can be equipped with grating to remove impurities and hydraulic covers to protect against adverse weather conditions. Haarup has a large selection of steel outlet chutes for installation in the concrete structure of the ground bins. If necessary, geothermal heating systems can be used to keep the bins frost-free.
