Results of industry testing of multiple use rock-cutting picks

Recycling possibilities for reducing waste from cutters on combined cutter-loaders and road builders

“…Thanks to the high degree of their heat treatment, the lifespan of the replacement heads averaged 50-60 production metres. The test results, published by Prokopenko and Ludzish (2014) and Prokopenko et al (2015b) demonstrated that the cutters could stand nine operating cycles (Figure 4).…”

“…Other researches (Bolobov et al 2012;Khoreshok et al 2012;Mamet'ev et al 2015;Kolesnichenko et al 2012) present test results of tangential rotary cutters operating on mining machines in mines in Kuzbass (Russia) and recommendations to improve their design. Advanced design of cutters with replaceable reinforcing cells, removable head, secured shank, etc., are offered in various scholarly proceedings (Bell, 2013;Bookhamer and Swope, 2014;Monyak et al, 2014;Parrott, 2014;Prokopenko et al, 2015bProkopenko et al, , 2016. Using ellipsoid cutter tips instead of conical ones is discussed by Khoreshok et al (2013).…”
