Jaw Crusher BB 51

Jaw Crusher  BB 51

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.

Application Examples

alloys, basalt, bones, 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 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.
As soon as the sample is smaller than the discharge gap width, it falls into a removable collector. The continuous gap width setting with digital display ensure optimal size reduction in accordance with the set gap width value.
