Characteristics of microcracks in vanadiumtitanium magnetite crushed by high pressure grinding roll (HPGR) and conventional jaw crusher (JC) were investigated. In crushing by both HPGR and JC, stress cracks, intragranular cracks, and cleavage cracks were developed. Stress cracking was the initial stage and fundamental basis of fracture.
HPGR technology is a qualified alternative for largescale comminution circuits and is becoming ever more popular in minerals processing. The technology's working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls.
HighPressure Grinding Rolls (HPGR) The HPGR technology has been identified as the most attractive grinding option, given the data obtained from the comminution testwork conducted in 2009 and in 2017–2018. During 2020, representative samples from different lithologies of the mine plan were sent to a laboratory in USA for pressure bed testing ...
