Innovative logistics solution to handle rock material sizes of 0-22 mm in silos


January 08, 2008


Kellve Bulkteknik and Velde Pukk, one of Norway's leading suppliers of gravel - and rock material has sealed an agreement worth over 35 MSEK for delivery of a crusing- and screening plant to produce ballast and filler to asphalt and concrete. The plant is a turn-key solution from the Kellve-group and the project is includes projecting, design, production, technical coordination of different suppliers in the project, mechanical montage and start-up of the plant.

The plant will handle, crush and screened sizes from 2-22 mm through traditional screens and materials below 2 mm are separated in 3 different sizes in a wind-screening plant, where the smalest sizes is from 0 to 0.063 mm. From the screens, the material is distributed to 10 storage silos. The material is dosed in different sizes to an asphalt plant by the silo, alternative to a new concrete station – on the other side of the silo.

There is also possibility to load out weighed ”concrete grits” to truck. Furthermore, one can load out each individual quality direct from a silo to truck or dumpers. There is also possibility to add further material direct from a pocket to the crusher or from another pocket direct to” the concrete grit”.

Lars's Jonsson, manager for project sales says in a comment, ”this order is a good example of the wide range within Kellve Bulkteknik when it comes to solve the bulk material logistics for our customers'. It is a strategically important order since it is that first bigger plant in order to handle ”concrete grits” from crushed rock material.

Kellve Bulktekniks delivery covers among other thing 22 band conveyors with 4 of the conveyors in conveyor bridge, flexowell belts placed on weighing-cells. 10 silos holding between 600 and 850 tonne each, with a diameter of 6 m, approximately 23-25 m high. Moreover the delivery comprices feeding equipment, dosing eqiopment, silo tripods, discharge equipment, a building around the silo including superstructure for screens and conveyors. The building is 31 m long, 16 m broad and 40 m high.

The plant will be ready for production in summer 2008
