PAES 205

• Actual capacity


  The weight of the threshed grain collected from the main grain outlet per unit time
• Clean threshed grain


  Threshed grain with 100% purity exclusive of the empty grains and other impurities
• Concave clearance


  The clearance between cylinder threshing elements and concave component
• Concave grate


  Concave component - an iron grill frame partly surrounding the cylinder on which the threshing elements rub, shear and/or impact the cut plants
• Corrected capacity


  The corrected capacity of the thresher at 20% grain moisture content (wet basis), grain-straw ratio of 0.55 and 100% purity
• Cylinder length


  The distance between the outermost points along the cylinder base axis
• Cylinder peripheral speed


  The equivalent linear speed of the cylinder tip when running at normal operating speed, expressed in m's
• Effective cylinder diameter


  Outside diameter generated by the outermost point of the cylinder threshing elements
• Grain-straw ratio


  The ratio of the weight of the grains present in the panicles, to the total weight of the grain and straw in the same sample
• Lower concave


  A semi-circular shaped wire mesh or bar grate covering the lower portion of the threshing chamber which causes the grains to separate from the panicles
• Primemover


  An electric motor, or a gasoline or diesel fed engine used to run the thresher
• Running-in period


  Preliminary operation of the machine to make various adjustments prior to the conduct of test
• Threshing output


  The weight of the threshed grains collected at the grain outlet
• Total grain input


  The sum of the weights of collected threshed grains and all threshing losses
• Upper concave


  Semi-circular shaped grate at the upper portion of the threshing cylinder with louvers which assist threshing and axial movement of the straw
