RYFAMA Return-end of Belt Conveyor may cooperate with belt conveyors of various belt width, using the suspended structure or supporting structure (supported on the floor).
Return-end of belt conveyor can be applied in the technical solution where one conveyor is over-lapping the other one and they are advancing simultaneously at the area of loading point of excavated material. One of these means of transport is a belt conveyor technically approved and certified, the end of which is equipped with return-end of RYFAMA type. At the same time, the return – end is used as a driving sets substructure for Beam Stage Loaders.
The said return-end solution creates optimal conditions for overpouring of excavated material from one conveyor onto the other, thanks to use of a special tail-end U shaped trough and its rigid construction located on the upper part of the conveyor.
The conveyor belt is rewound through a barrel mounted on the reversible pan set of Ryfama Return-end. The belt onto the barrel passes from the lower to the upper section which is a section transporting run of mine.
The conveyor pouring excavated material onto Return-end may be of various structure, wherein, its discharge driver or passive return-end driver is permanently mounted on a return-end subdriving trolley. The return end subdriving trolley and the return-end blocking trolleys are joint to each other by means of set of hydraulic cylinders and thanks
to that, it is possible their mutual moving and blocking towards to Returned-end pan sets.
The modular construction of Belt Conveyor Return-end allows optional configuration of its length (understood as overlapping of pouring conveyor onto the belt conveyor return-end) which enables free movement of pouring conveyor without need of belt conveyor length adjustment (pouring conveyor with a discharge located above the
return-end overlaps the belt conveyor). Lengthening or shortening of the return-end is done by adding (subtracting) basic pan sets to the pan set structure (connection by means of links).
