Production of crushed rock aggregate involves screening (scalping) to remove fines and waste material followed by crushing and screening to produce material with specified size grades. Crushing is carried out to reduce the size of the excavated material from large blocks (up to a metre across) to a size finer than 20 to 50 mm (Figure 2).

Screenings, otherwise known as FA5 or limestone screenings, consist of crushed limestone that is the by-product of the rock mining process. When crushing rock for gravel or rip rap, the material is passed through a variety of screens to catch the larger pieces. The limestone screenings is what falls through and is collected for other purposes.

Screening Theory and Practice 1 Part 1. Theory of Screening The purpose of screening is to separate from a granular substance particles that are smaller than the screen opening from those that are larger. This is not as simple as it sounds, and the difficulties compound as the opening becomes smaller. For example, if a sample of a crushed

produce crushed aggregate, or to produce manufactured sands. Crushing generally is carried out in one or two stages, although three-stage crushing may also be performed. Following crushing, the material is returned to the screening operation for sizing. The material that passes through the scalping screen is fed into a battery of sizing screens,

Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.

For efficient screening, the material bed should not reach a depth that prevents undersize from stratifying before it is discharged. Depth of bed (in dry screening) should not exceed four times the opening size at the discharge end of the screen. Consequently, with a 12 mm opening, the depth of bed at the discharge end should not exceed 50 mm
