To EN1744 part 1

• 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 re-producibility 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 LAG450.
• 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 LAG450 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).
