Size Reduction and Energy Requirement ScienceDirect
This method of estimating mill power requirement has been successful in recent years The Metso abrasion test is mainly used to assess hammer wear in an impact type crusher a hammer mill hence the much higher rotational speed whereas the Bond abrasion test is used in tumbling applications balls rods and mill liners as
Size reduction control in cone crushers ScienceDirect
Consequently the most common control objective is still to regulate the crusher load crusher power or crusher main shaft piston pressure or the closed side setting the shortest distance between crushing liners not the actual size reduction Given the control hierarchy in Fig 6 a practical requirement for a KPI is that it should be
