Difference Between Single & Double Toggle Jaw Crusher
A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers.The lower throughput statement is a bit misleading because it's partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could be closer to that of a …

The effect of crusher type on printed circuit board assemblies
Commonly, the liberation degree increases as the fraction becomes finer, which was seen in both of the crushers as well. However, a clear difference in the distributions was detected. In the larger size fraction (>31.5 mm), below 10 w% of the PCA was fully liberated with the cutting mill, whereas for the hammer mill the figure is above 30 w%.
