TYPES OF JAW CRUSHERS In the dodge jaw crusher the moving jaw is pivoted at the bottom. As minimum movement is at the bottom it has a greater tendency to choke. In the Blake or jaw crusher the moveable jaw is pivoted at top. The  greatest amount of motion is at the bottom which means it has the little tendency to choke  Dodge jaw crusher  Blake jaw crusher
