BB 500 Jaw Crusher

The Jaw Crusher BB 500 is used for 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 500 ideal for sample preparation in laboratories and industrial plants.

For small amounts of sample the BB 500 is 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 BB 500 with its steep crushing chamber and powerful drive provides for very effective crushing kinematics.

Application Examples

alloys, basalt, cement clinker, ceramics, chamotte, coal, coke, construction materials, feldspar, glass, granite, minerals, quartz, ores, oxide ceramics, rocks, silicon, slag, …

Function Principle

The Jaw Crusher BB 500 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 wedge-shaped area between the fixed crushing arm and one oscillating with high frequency. This motion ensures a consistent gap width in the stroke cycle so that the sample is crushed to the set fineness in one working step. Two massive flywheels transmit high impulse forces to the crushing jaws. The innovative design permits using both sides of the jaws thanks to a 180° rotation.

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.
