Over the past year and a half, M.I.P. has supplied Casteleyn T.R.S. in Meulebeke with4 composite silos for the storage of lime and cement; raw materials for their lime & Benor concrete plant.
Casteleyn has been active in the construction sector for 35 years. Previously, the company focused mainly on utility infrastructure, but over the last decade it has increasingly been involved in road construction, sewerage works and the construction of all kinds of structures for both private and public clients. To carry out many of these projects, Casteleyn uses raw materials such as lime and concrete, which are produced in its own plants.
Lime plant
In the summer of 2021, M.I.P. supplied two composite silos for lime storage at Casteleyn’s lime plant. The lime is mainly used for processing building materials (raw materials with a code between 311 and 911) so that they can be given a second life as a foundation beneath building slabs or as a supplement in sewerage works. The composite, or Glass-Fibre Reinforced Plastic (GFRP), silos fully met these expectations.
Concrete plant
When Casteleyn decided in the summer of 2022 to install a new Benor-certified concrete plant, contact was therefore quickly established with M.I.P. This was partly because we had already demonstrated in the past that we could offer short lead times. M.I.P. was awarded the contract to supply two additional composite silos for cement storage at the Benor concrete plant.
This plant, which will come into operation at the end of October 2022, will enable the supply of construction products bearing the Benor CE certificate. This label assures the customer that the products have undergone thorough internal quality control, under the supervision of an independent, external certification body.
Silo technology
Each of the four silos is 12 metres high, has a diameter of 3 metres and a capacity of 55 m³. For safety reasons, each silo is fitted with a pressure relief valve. The screw conveyors and valves for discharging the minerals were supplied by Bulk Processing Systems in Willebroek (Belgium). The silos have been raised on a base to give the screw conveyors the correct angle of inclination for trouble-free discharge. The circumferential platform can be safely accessed via a cage ladder.
Composite
Casteleyn deliberately chose composite as this construction material minimises the risk of condensation forming inside the silos. This is essential when storing moisture-sensitive products such as cement, which can otherwise harden. Furthermore, the seamless, smooth silo walls, in combination with the aeration systems in the hoppers, ensure an optimal flow pattern. Another reason for Casteleyn to opt for composite is the colour fastness of the coating on the silos. The silos are fitted with a resin-rich, coloured, UV-resistant coating bearing the customer’s logo.
