Abstract

The following report intents to show an elaborated methodology for compactors and baler presses selection based on volume displacement calculations, as opposition to traditional mass displacement calculations. Traditional methods based on mass displacement by time unit (kg/h) show the following disadvantages: The amount of processed mass (pressed) is not constant, but rather depends on the material characteristics (density), and therefore the hourly mass production depends on the material type. The compaction grade depends on material mechanical characteristics (elasticity), therefore the hourly mass production depends on the material type. In some machines, cylinder displacements also depends on material mechanical characteristics. Based on these effects, we can deduce that the production data given by manufacturers are applicable alone to a concrete kind of material and under some certain conditions, not being able to predict the equipment behaviour in front of new materials. This paper relates how to calculate the influence of these effects over the machine hourly production, showing a new selection point of view focused in the hourly volume production (m3/h) rather than the hourly mass production.
