摘要
Transfer chutes are critical areas within conveyor transfer systems in terms of maintenance and high levels of energy consumption. Appropriate chute design allows material stream to be uniformly fed on the receiving conveyor with a desired stable tangential speed. This reduces the motion resistances and belt wear. Any construction work associated with a transfer chute should be preceded by a thorough analysis of the stream trajectory. The simplest case is to consider the motion of a single grain. The article presents an analysis of grain motion in a parallel chute and a methodology of calculating the impact angle and tangential speed of the grain at the point of contact with the receiving conveyor belt. Based on calculations made on developed model it was determined which of the basic input parameters have the most significant impact on the changes of observed output parameters.
