Jaw Crushers

Retsch offers Jaw Crushers used for the rapid, powerful crushing and pre-crushing of mediumhard, hard, brittle as well as tough materials, making them very highly positioned in the sample preparation chain. The variety of materials offered, their efficiency and safety make them ideal for sample preparation in laboratories and industrial plants, where they are usually used in rough conditions. However, they are also suitable for on-line quality control of raw materials. The jaw crushers are available in 8 different sizes: BB 50, BB 100, BB 200, BB 300 and the bigger models BB 250, BB 400, BB 500 and BB 600. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material.
Feed sizes range from 40 mm to 350 mm, depending on the model.
The main fields of application of jaw crushers are construction materials, mineralogy and metallurgy, ceramics and glass, materials research and environmental analysis.

BB 50

The Retsch Jaw Crusher BB 50 is specially designed for sample preparation in the laboratory This model is suitable for the quick, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. The space-saving, dust-tight instrument fits on any laboratory bench and is optimal for gentle crushing of small amounts of sample with large feed sizes, without loss. In order to avoid metallic contamination, its grinding chamber is made out of ceramic materials. With the digital gap width display and zero point adjustment, BB 50 allows for reproducible results. It can be applied for crushing the following materials: alloys, basalt, bones, cement clinker, ceramics, chamotte, coal, coke, construction materials, feldspar, glass, granite, minerals, ores, oxide ceramics, quartz, rocks, silicon, slag, etc.

BB 100 / 200 / 300 / 250 / 400 / 500 / 600

Jaw Crushers BB 100, BB 200 and BB 300, as well as bigger models BB 250, BB 400, BB 500 and BB 600 are used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. The variety of materials offered including heavy-metal free steel, combined with their efficiency and safety, makes these Jaw Crushers ideal for sample preparation in both laboratories and industrial plants. For small amounts of sample BB 200 / 300 / 250 / 400 / 500 can be used batch-wise, whereas for larger amounts they can be operated continuously. Furthermore, control of the gap width and zero point adjustment allow for reproducible results. The Belleville spring washer protects the Jaw Crusher from overloads and in conjunction with maintenance- and lubricant-free sliding bearings guarantees a long service life. In addition, the BB 600 is ideally suited for continuous operation in automatic installations and sampling stations, and the BB 500, with its steep crushing chamber and powerful drive, for very effective crushing kinematics.
