The beam flail should be replaced when the outside diameter is worn to approximately 1-5/16 inch or the inside diameter elongates to approximately 3/4 inch.

Pentagonal Flail

The pentagonal type flail is manufactured from high carbon steel that is through hardened for additional service life. Each section of the five sided design features a small, tungsten carbide insert that is held in position with copper brazing. It is highly effective for scabbling or scarifying and delivers medium to coarse finish texture. FIGURE 9.

Suggested Applications:

1)Heavy duty asphalt and concrete scarifying.

2)Heavy duty descaling of steel decks.

The pentagonal flail is designed for more aggressive and rapid removal of a surface in comparison to the beam flail. The addition of the tungsten carbide inserts contributes to its long service life and higher production rates. The use of tungsten carbide is also the main reason for the cost differential between it and the other flails. The design configuration yields a rather coarse surface finish and texture. For many job applications, this finish and texture will be satisfactory. Some applications may require an additional smoothing process. If the resulting surface finish is too coarse to meet specifications, it can be smoothed with the use of the star or beam flail.

SERVICE LIFE 10

The pentagonal flail should be replaced when two successive tungsten carbide inserts break off or the inside diameter elongates to approximately 3/4 inch. In service, the flail body will wear much faster than the tungsten carbide inserts. The copper brazing used to weld the inserts into the body can fail and an insert break off. The flail can still be used in service. It will just wear a little faster and more uneven in that particular area. As a general rule, a pentagonal flail can be utilized until body wear will no longer support the tungsten carbide inserts.

Spacer Washer

Spacer washers are stamped from high carbon steel and heat-treated for additional service life. FIGURE 10.

FIGURE 10

Spacer washers serve the following functions:

1)Reduces the number of flails required to be mounted on the scarifier block, thus reducing purchase and operational costs.

2)Arrange the flails in a sequence or pattern that minimize "blind" or "open" spots. Normally, at least one spacer washer is inserted between two consecutive flails. A scarifier block set up with only star, beam or pentagonal flails will not penetrate the work surface at satisfactory rates. This configuration will minimize the hammering or impact action of the flails.

Variances in material thickness and manufacturing processes can affect the final thickness of both flails and spacer washers. Because of this occurrence, trial and error is important for assembling flails and
