The BB 100 is a robust and powerful forced-feed Jaw Crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedge shaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity.
