The modified Proctor method uses a 10lb hammer with 18in (457mm) drop height for compaction. Automatic/mechanical compactors are also available to make this process easier. After compaction, the collar is removed, and excess soil is carefully trimmed with a straightedge tool so the compacted soil is flush with the top of the mold.

Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers.

Most crushers employ a combination of all these crushing methods. Impact Impact refers to the sharp, instantaneous collision of one moving object against another. During the collision, both the objects may be moving, such as a cricket bat hitting a fast moving ball, or only one object may be moving, such as a rock being struck by hammer blows.
