The Jaw Crusher BB 51 has been specially designed for sample preparation in the laboratory. The space-saving, dust-tight instrument fits on any laboratory bench. Small amounts of sample with large feed sizes are crushed gently and without loss.

The Jaw Crusher BB 51 is a robust and powerful forced-feed crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedgeshaped 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.
