Coarse and initial size reduction of hard to brittle materials
Retsch jaw crushers are used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Their variety of materials offered, such as heavy-metal free steel, efficiency and safety makes them ideal for sample preparation in laboratories and industrial plants. The throughput and grind size depend on the type of instrument, the gap width and the crushing properties of the sample. jaw crushers are particularly suitable for the preparation of rocks, minerals, ores, glass, ceramics, construction materials, brittle metal alloys, slag, synthetic resins and many other hard, brittle substances.
Superiority in detail – technology from RETSCH
With respect to the subsequent analysis, jaw crushers are always at the very front of the sample preparation chain. They are used for pre-crushing mainly hard and brittle materials. The fine grinding method depends on the analysis to follow and can be carried out with either
■ ball mills and mixer mills,
■ mortar grinders, or
■ disc mills and vibratory disc mills.
Many unique details show that RETSCH jaw crushers are the ideal choice when the rapid and gentle crushing and pre-crushing of hard and brittle materials is to be accomplished.
Top performance in many areas
RETSCH jaw crushers are primarily used in laboratories and pilot plants under industrial conditions, but can also be used on- line for the quality assurance of raw materials. The jaw crushers are offered in four different models: BB 51, BB 100, BB 200 and BB 300. With a feed size of between 35 and 150 mm and depending on the model, the jaw crushers can achieve a grind size of down to 0.5 mm. The main fields of applications are:
■ Construction materials
■ Mineralogy and metallurgy
■ Ceramics and glass
■ Materials research
■ Environmental analysis
Their good grind size and their high crushing ratio demonstrate the great efficiency of RETSCH Jaw Crushers.
Versatile applications and long working life
Breaking jaws for RETSCH Jaw Crushers are available in various materials and thus allow versatile applications and a long working life.
They are available in:
■ Manganese steel
■ Stainless steel
■ Tungsten carbide
■ Zirconium oxide, partially yttrium-stabilized
■ Steel free from heavy metals
No matter whether wear-resistance or heavy-metal-free size reduction is required – for every application there are a suitable grinding tool available.
Continuous gap width adjustment and display
The gap width is set by using an analog scale. The BB 51 has a digital display with a setting and read-off accuracy of 0.1 mm. This means that reproducible crushing processes are possible, particularly since it is possible to compensate for wear.
Zero-point adjustment to compensate for wear
Depending on the material and the throughput, sooner or later the breaking jaws will start to show signs of wear. This means that the set breaking jaw distance or the crushing gap will increase with time. In order to still be able to obtain reproducible crushing results this wear must be compensated. With jaw crushers whose gap width can only be set in fixed steps, compensation for wear is not possible. This means that reproducibility can no longer be assured. In comparison, RETSCH Jaw Crushers can be continuously adjusted and therefore breaking jaw wear can be compensated. This is done by slowly altering the gap width setting with the motor running until the breaking jaws are heard to come into contact.
The new zero point thus obtained is saved by pressing the reset key (BB 51) or readjusting the scale (BB 100 to BB 300). Increased user convenience combined with maximum working safety Safety is very important for RETSCH Jaw Crushers. The interior of the
feed hopper cannot be accessed by hands and the baffles prevent the sample material from rebounding. Integral Belleville spring washer packages and a thermal overload protection switch protect the jaw crushers against overloading. The hopper is hinged for easy cleaning (BB 100 to BB 300) or can be easily removed. The jaw crushers run very smoothly and quietly. Due to their solid design, RETSCH Jaw Crushers are virtually maintenance-free. RETSCH type BB 200 and BB 300 Jaw Crushers are also available in versions which can be included in process lines. Their robust design means that they are not only suitable for batch-wise operation, but they are also particularly suitable for continuous size reduction in on-line operation.

The on-line versions of the RETSCH Jaw Crushers are supplied without the feed hopper and motor protection switch. The three-phase
current version of the motor will be supplied as per customer’s specifications.
