Rail Topping System for Africa

Enviroflo/Nalco have recently commissioned a Rail Topping (or Rail Wagon Dust Suppression System) at a coal mine in Africa.

The mine loads coal into rail wagons and it is transported for several hundred miles. In transit, a significant percentage of the coal is lost from the exposed top surface due to windage. This leads to a number of problems:

The Enviroflo/Nalco solution is a fully automatic system to spray a solution of Nalco DUSTBIND onto the top of the material in the wagons after loading to act as an encrusting agent. This forms a strong and flexible bonded crust on the surface of the material with minimal moisture addition. The applied crust cures slowly to allow material settling.

Train Spraying

The majority of the equipment was pre-installed into a modified, insulated, lined and air-conditioned shipping container. On arrival at site the container was located on prepared foundations and the application equipment was unpacked and installed together with the interconnecting pipework.

Train Spraying

The following video demonstrates the operation of the automated system.
