Jaw Crusher BB 300



The Jaw Crusher BB 300 is used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Its variety of materials offered, including heavy-metal free steel and its efficiency and safety makes the BB 300 ideal for sample preparation in laboratories and industrial plants.

For small amounts of sample the Jaw Crusher BB 300 can be used batch-wise; for larger amounts it can be operated continuously. Control of the gap width and zero point adjustment allow for reproducible results. The Belleville spring washer protects the unit from overloads and in conjunction with the central lubrication guarantees a long service life.

Function Principle

The Jaw Crusher BB 300 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.

As soon as the sample is smaller than the discharge gap width, it falls into a removable collector. The continuous gap width setting with scale ensures optimum size reduction in accordance with the set gap width.
