Bi-directional transport has been practiced before in cement operations.,

We have done this in iron ore with 4000 t/h on carry strand and 1000 t/h on return.

Others in the forum have noted similar installations in other materials.

I believe Koch (now defunct), has made such installations in limestone and/or clinker in one direction and coal on return using pipe conveyors.

You must be careful on cleaning or controlling contamination between products. ■

What is the distance you are dealing with from a to b ? ■

dear Mr Schilperoort,

Why not making a preliminary desgn and evaluate the result of that design for the 2 materials.

There should be enough experience available on coal belts.

On cement, it would be somewhat more difficult because of dust swirling up from the belt and the transport on steep angles, because of the risk of fluidizing by the roller vibration.

( The fluidizing property of the cement will be the main concern)

One belt for two products allows no 2 commodities at the same time.

Coal can be transported in the open (cement and clinker cannot)

May be a combination of a single direction belt for coal or a bi directional belt for coal and clinker and a pneumatic conveying system for the cement is also feasible

a capsule pipeline will allow you to move two or more commodities at the same time.
