Vibrating Screen Working Principle. Very close screening is not required and some sort of moving bar or ring grizzly can well be used, but the modern method is to employ for the purpose a heavy duty vibrating screen of the Hummer type which has no external moving parts to wear out ; the vibrator is totally enclosed and the only part subjected to wear is the surface of the screen.
A scalping screen used as a finishing or dewatering screen would have a greatly reduced capacity. A finishing screen used as a heavy scalper would also have a greatly reduced capacity. The type of stroke, length of stroke, screen rpm, timing angle, and incline of the screen greatly affect the basic capacity.
