This invention relates to a particulate material thrower comprising an endless belt running over a pair of rollers which provides a loading end and discharge end on the belt, and a thrower wheel running adjacent to the belt over the roller at the discharge end. The thrower wheel is characterized by a plurality of vanes extending between the side flanges of the thrower wheel wherein the vanes are shaped in a manner so as to collect material on the belt before throwing. One advantage of the invention is to significantly increase the amount of acceleration that can be given to particles or other particulate matter without such energy being imparted to the materials quickly or in single step so that the material such as grain is not damaged. Another advantage of the invention is that it reduces side spillage or leakage from the belt.
