Jaw Crusher, Output: 300 kg / hr

Product Overview

The Jaw Crusher, Output: 300 kg / hr is a floor model designed for a throughput of up to 300 kg/h, suitable for many typical crushing tasks. It accepts feed sizes up to 90 mm. The gap width can be set stepless from 0 30 mm.

Depending on the sample material, particle sizes down to 2 mm can be obtained, resulting in a crushing ratio of 45. Its versatile usage includes continuous pre- and fine crushing in one step or process-line versions.

The jaw crusher series is available in 8 different sizes. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material.

Robust design, simple handling and cleaning are the features of the jaw crusher models. Small amounts of sample are processed batchwise; for larger amounts the crushers can be operated continuously.

Superiority in Detail

Robust design, simple handling and cleaning are the features of the JAW CRUSHER, OUTPUT: 300 KG / HR jaw crusher. For small sample amounts of up to 5 L the JAW CRUSHER, OUTPUT: 300 KG / HR can be used batch-wise; for larger amounts it can be operated continuously.

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 (e.g. a belt conveyor).

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 JAW CRUSHER, OUTPUT: 300 KG / HR jaw crusher features maintenance- & lubricant-free sliding bearings.

Wear Compensation by Zero-Point Adjustment

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. To still be able to obtain reproducible crushing results this wear must be compensated.

Jaw crushers can be continuously adjusted, allowing for compensation of breaking jaw wear. 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.

User Convenience Combined with Maximum Safety

Safety is a top priority with jaw crushers. The feed hopper with splash-back protection cannot be accessed by hand. A safety switch and the brake motor ensure an immediate stop if the unit is opened or switched on incorrectly.

For easy cleaning of the crushing chamber, the hinged hopper can be removed in a few simple steps. The jaw crushers run very smoothly and quietly and are virtually maintenance-free.

Jaw Crushers for Special Requirements

• Apart from the standard model, the JAW CRUSHER, OUTPUT: 300 KG / HR jaw crusher is also available in special versions adapted to particular application requirements.
• Heavy-metal free crushing
• All jaw crushers are available in a heavy-metal-free version. The JAW CRUSHER, OUTPUT: 300 KG / HR can also be supplied in a special version suitable for crushing semiconductor materials. This includes plastic lining of feed hopper and receptacle as well as breaking jaws and wear plates of tungsten carbide.
• Thus, the sample does not come into contact with metal materials at any point and no abrasion of the grinding tools impairs the purity of the sample material.

Functional Principle :

The Jaw Crusher, Output: 300 kg / hr 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 wedge shaped 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 within the jaw crusher. The continuous gap width setting with scale ensures optimum size reduction in accordance with the set gap width.
