There are key requirements that an unloader needs to fulfill to maintain an advantage in the increasingly competitive business of grain transportation. The unloader is the backbone of operations at a terminal. Fluctuations in capacity and downtime have a significant impact on costs and overall operation.
That’s why the Portalink, Bühler’s continuous mechanical unloader, has bee designed to achieve maximum efficiency and unrivaled reliability, with low operating costs – enabling you to achieve your business goals.
The marine leg is the key to the efficiency of the overall system and the heart of the machine. Portalink’s marine leg is a vertical chain conveyor that unloads product in a compact column at a rate of 300 to 1,300 t/h. The low conveying speed protects the product from degradation. Low energy use keeps operating costs down. The automatic sink-in mechanism maintains the intake boot at an optimal level within the product during the unloading process, enabling the system to unload
at constant full capacity.
The Portalink unloader consists of a gantry construction with a swiveling top section, a trussed horizontal boom, and the marine leg with kick-in/kick-out system. The unloader transports bulk product from the ship’s hold to the pier at low speed using two independent high-performance chain conveyors.
Portalink has a wide range of movement. The unloader can be designed to travel on rails or equipped with steerable tire wheels. The boom can be lifted, lowered and swiveled as required. In addition, the kick-in/kick-out system enables the marine leg to move through the hatch and reach the product
below the rim of the cargo hold,
