Jaw Crusher BB 300
The Jaw Crusher BB 300 is used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Its variety of materials offered, such as heavy-metal free steel, efficiency and safety makes it ideal for sample preparation in laboratories and industrial plants.
Application Examples
alloys, basalt, cement clinker, ceramics, chamotte, coal, coke, construction materials, feldspar, glass, granite, minerals, ores, oxide ceramics, quartz, rocks, silicon, slag, ...

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 ensure optimal size reduction in accordance with the set gap width value.
