Too high of a ratio (>2.5 hp/hammer) may result in poor hammer life. If the body or pin hole of the hammer are wearing before the hard facing or if there is excessive grooving on the hammer pins, increasing the hammer quantity is a common solution. The most common hammer patterns are in the range of 1.4:1 to 1.9:1 hp/hammer. Hammer …
