KVM Selected at Mountsorrel

摘要

Last year Lafarge Aggregates made a significant adjustment to the balance of coated stone production at their flagship Mountsorrel granite quarry in Leicestershire by replacing a 60 tonnes/h Quadrare batch-heater plant with a new 210 tonnes/h Freja 3500/250 asphalt plant from Danish manufacturers KVM International A/S. The change was made to meet today's growing demand for high-specification thin wearing courses, a task that the batch-heater unit and the quarry's other existing coating plant ― a Standard Havens drum-mix unit ― were struggling to fulfil. Before selecting a supplier Lafarge set up a project team to identify and define the required plant specifications. The team soon highlighted a number of time constraints and space limitations that meant the new plant would have to be constructed to very tight tolerances and within a restricted time frame. Foremost among these considerations was the need to have the plant fully up and running in time to meet last year's surfacing requirements on the M6 Toll. This was compounded by a 21 m height restriction and the need to 'integrate' the plant with the existing cold-feed system, an overhead RAP conveyor to the Standard Havens plant, the original bunded bitumen storage area, and a new hot-storage/load-out facility.
