Jaw Crusher with Single Toggle Plate Design Jaw Crusher Classification. Jaw crushers are classified based on the position of the pivoting swing jaw. There are three main jaw crusher types: Blake crusher – the swing jaw is fixed at the lower position. Dodge crusher – the swing jaw is fixed at the upper position.
Jaw crushers are typically employed as tertiary units because of their large energy-storing flywheels and high mechanical advantage. ... Double-toggle Blake-type jaw crushers are so small and light that they lend themselves to portable applications. False. Gyratory crushers are the most efficient of all primary-type crushers. True.
The two most common types of concrete crushers are double toggle (blake type or overhead pivot movement) and single toggle (overhead eccentric movement). The main difference between both types of crushers is the mechanism that allows the movable concrete to compress materials.
