High-frequency vibrating screens - Wikipedia

The equipment capacity is almost directly proportional to screen width. This means that by increasing the length, there will be additional chances for passage, and will usually lead to increase in transmission and efficiency. In general, the standard size of screen length should be two to three times the width. [5]

Trommel screen - Wikipedia

A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material ...

Room Cavity Ratio (RCR) - FMPedia Wiki - Knowledge Library

Room Cavity Ratio (RCR) Room Cavity Ratio (RCR) LIGHTING: A shape factor (for a room, etc.) used in lighting calculations. RCR = 5H (L+W) / L x W, or, alternately, RCR = (2.5) Total Wall Area / Floor Area. Where H = height, L = length and W = width of the room. A cubical room will have an RCR of 10; the flatter the room the lower the RCR.

The Relationship Between Pressure and Flow in a Compressed Air System

Therefore, out of these two relatively small leaks, the 200-hp compressor was losing essentially one tenth of its overall capacity. A handy rule of thumb to remember is that a 1/4-inch opening/orifice will leak approximately 100 cfm at 100 psig. Remember, compressed air is "stupid" (i.e. it will follow the path of least resistance).
