Jaw crushers can reduce the size of crushable trash, making it easier to load and transport. Crushed material is significantly easier and safer to load, transport, and dump. This option is frequently used in the construction or demolition business, when large amounts of breakable material, like concrete, require processing in order to efficiently remove the debris.
Jaw crushers are classified on the basis of the position of the pivoting of the swing jaw:
Blake crusher-the swing jaw is fixed at the upper position
Fote crusher-the swing jaw is fixed at the lower position
Universal crusher-the swing jaw is fixed at an intermediate position
The Blake crusher was patented by Eli Whitney Blake in 1858. The Blake type jaw crusher machine has a fixed feed area and a variable discharge area. Blake crushers are of two types- single toggle and double toggle jaw crushers.
