New wear test devices narrow the gap between research and practice
Experimental research plays a key role in solving wear problems. The following four novel wear test devices were developed in the DEMAPP programme: a dual pivoted laboratory jaw crusher, an impeller-tumbler impact-abrasion tester, a high-speed slurry pot tester, and a high velocity particle impactor (HVPI) for wear model and simulation validation. The test devices were...
Light and efficient structures for next generation mineral crushers
New material solutions were applied to Metso crushers. New materials offered advantages, such as improved usability, durability and energy efficiency, differentiating Metso crushers from its competitors.
Dual Mass Balancing of a Jaw Crusher
The inertia forces and vibration amplitudes of a jaw crusher have been balanced approximately by 90 % by using two balancing masses rotating in opposite directions. Dual mass balancing serves several benefits such as lower stress, vibration and noise levels of the machine, and an increased fatigue life.
