PAES 205:2015
the weight of the threshed grain collected from the main grain outlet per unit time
actual capacity
threshed grain with 100% purity exclusive of the empty grains and other impurities
clean threshed grain
the clearance between cylinder threshing elements and concave component
concave clearance
concave component
an iron grill frame partly surrounding the cylinder on which the threshing elements rub, shear
and/or impact the cut plants
concave grate
the corrected capacity of the thresher at 20% grain moisture content (wet basis), grain-straw
ratio of 0.55 and 100% purity
corrected capacity
the distance between the outermost points along the cylinder base axis
cylinder length
the equivalent linear speed of the cylinder tip when running at normal operating speed,
expressed in m/s
cylinder peripheral speed
outside diameter generated by the outermost point of the cylinder threshing elements
effective cylinder diameter
grain content
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
grain-straw ratio
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
lower concave
an electric motor, or a gasoline or diesel fed engine used to run the thresher
primemover
preliminary operation of the machine to make various adjustments prior to the conduct of test
running-in period
the weight of the threshed grains collected at the grain outlet
threshing output
the sum of the weights of collected threshed grains and all threshing losses
total grain input
