An alternative to transport clinker at inclines over 45° are TC box conveyors. Similar in composition and specification to TP conveyors, TC box conveyors include a metal belt that conveys the material and which is made up of a series of boxes placed at a distance corresponding with twice that of the chains that connect them underneath. The front wall of one box mounts onto the rear wall of the neighbouring box to avoid any loss when the material is loaded. The chains connect the boxes to each other and also provide the required articulation. The chains have an “anti-rotation” feature, allowing the belt to be supported in an almost planar position even though the supports are placed four times further apart than the pins of the chains. One box in every two is equipped with a pair of rollers with bearings that guide and support the belt and rest on the tracks
Material is conveyed on the upper branch only, where several loading points are allowed.

Specification of TC Box Conveyor
– possible inclination is up to 60′
– no powder leakage throughout the life of the conveyor
– minimum curve radii of 10m are permitted
