To screen means tp prevent passage... grinder plates do just the
opposite, they enable passage, the edges of those perforations are the
complementary part of the cutting blade, the other half of the
shearing mechanism... minus the grinder plate would be tantamount to
scissors with only one blade. Without the grinding plate the grinder
won't grind, it would cease to be a grinder. A meat grinder is a very
well engineered tool, there are no wasted parts, all its five parts
are necessary; the body, the auger, the plate, the blade, and the
retaining nut. Meat grinder web sites refer to grinder cutting
plates, not screens.
