• Material feed size <90 mm ¨C
  
• Grind size d90 <2mm
  
• Complies with EN1744 part 1

Used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Efficiency and safety makes them ideal for sample preparation in laboratories and industrial plants. 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.

• High throughput, high degree of size reduction
• High final fineness (down to d90 <2 mm)
• Continuous gap width setting
• Scale for gap width display
• Zero point adjustment for wear compensation
• Particularly economical
• Breaking jaws made of 4 different materials
• No-rebound feed hopper with quick-release clamp
• Brake motor with safety switch
• Easy-to-clean crushing chamber

Continuous gap width adjustment and display

The gap width is set using an analogue scale. This means that reproducible crushing processes are possible, particularly since it is possible to compensate for wear.

Zero-point adjustment to compensate for wear

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. This Jaw Crusher 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 readjusting the scale.
Robust design, simple handling and cleaning are features of the AG450.
For small amounts of sample the jaw crushers can be used batch-wise; for larger amounts they can be operated continuously. Neutral-to-analysis results are ensured by four different types of material for the breaking jaws and wearing plates. The interior of the no-rebound feed hopper cannot be accessed by hands. It is hinged so that the crushing chamber is easily accessible for cleaning. Only a few steps are needed to exchange the breaking jaws and clean the jaw crusher. The crushed sample is collected in a removable collector. For larger amounts or continuous crushing operations, the sample collector can be replaced by customer-specific solutions. The grinding chamber is enclosed almost dust-tight. By the aid of the connector for dust removal, any fine dust which could contaminate the sample or the work environment can be collected in an industrial vacuum cleaner. A safety switch and brake motor ensure an immediate stop if the unit is opened or switched on incorrectly. A Belleville spring washer integrated in the spindle adjustment provides additional overload protection. The eccentric spindle, which moves the crushing arm is driven by a robust brake motor via V-belts. The largest belt pulley also acts as the flywheel to ensure uniform and smooth operation.

The AG450 Jaw Crusher is supplied with a grooved set of Manganese steel breaking jaws.
Manganese steel is a material whose structure becomes compressed under pressure and becomes harder with time (cold hardening).
