Abstract
A fan is passively, detachably carried by the grinding head assembly of a railroad track rail grinding machine. The fan plate is oriented above the grinding stone and rotates with the grinding stone during grinding operations. A downward draft of air is induced by the fan to limit the dispersion of sparks, grinding stone residue, and other byproducts of the grinding operation. Water, with or without a surfactant added, can be introduced into the downdraft.
