Jaw Crusher (JC)

What’s the benefit?

The Jaw Crusher (JC):

  • Quickly crushes the hardest (3 and above on Mohs scale) and most abrasive materials.
  • Is easily adjustable and precise with respect to discharging particle size.
  • Is optimal for both continuous batch-wise operation.
  • Can be equipped with a sieve for handling sudden large portions of material flow.
  • Has a high crushing ratio. Up to 45 for shown model with sieve.
  • Has multiple access panels making it easy to maintain, clean and inspect.
  • Is bolted together making it easy to replace spare parts

 

  • Is equipped with a rotation guard, that monitors whether it works correctly.
  • Has a solid design and very reliable performance.

What does it do?

The Jaw Crusher (JC) is designed for particle size reduction of the hardest and most abrasive materials. Materials should be dry or slightly wet, but not sticky. Possible materials include iron pellets, quartz, fireclay, stones, basalt, building materials, glass, ores, minerals of any kind, silicon fines and nickel and copper concentrate containing lumps.

The Jaw Crusher can be used as a primary, secondary, or even tertiary crusher. As an addition a sieve can be attached for handling sudden large portions of material flow for example from big bags or batches from ducts.

 

Variants.

The JC comes in different size variants depending on customer requirements regarding size and material flowrate. For more information please don’t hesitate to contact us.

How does it do it?

The Jaw Crusher consists of an inlet hopper, an outlet, a base frame, a fixed jaw plate, and a movable jaw plate (pitman). The pitman is driven by an electric motor.

Sample material is fed by gravity into the Jaw Crushers inlet opening and down into the crushing area. Here it is crushed by the two jaws, and when the sample material particle size is small enough it falls through the outlet. Particle output size is determined by jaw distance, which can easily and precisely be adjusted with the adjustment handle enabling a stepless gap adjustment.

Optionally a sieve, driven by an unbalance motor, can be attached to the Jaw crusher before the inlet. With the sieve attachment sample material is let in through the sieve, where particle sizes over a certain limit are let into the JC to be crushed, while small particle sizes are let directly through for further processing. Tilted sieve design ensures efficient flow.

 

What are the technical details?

Drive unit: Electric motor.

Sensors: Rotation guard.

Indicative Dimensions (LxWxH): 1050x950x1150 mm. (Shown model with sieve).

Indicative weight: 300-360 kg. (Shown model with sieve).

Decibel rating: <70 dBA (No material throughput).

Housing material: Stainless Steel AISI 304/316 and/or painted galvanized mild steel.

Jaw material: Manganese steel, stainless steel, tungsten carbide or as required.

Feed size/ particle size (input): Varies with variant and costumer requirements. In general up to 85% of jaw opening.

Particle size (output): Adjustable through stepless gap adjustment. Down to 2 mm.

Options

  1. As an option a sieve can be attached to the JC for handling sudden large portions of material flow. The sieve option will ensure that only material in needing of crushing will enter the sieve.
  2. As an option a suction point for dust particles can be integrated into the JC reducing dust particles exchanged with the mechanism compartment and the surrounding area.

Nota bene

The JC outlet can be made as either a material drawer or as a tube leading to further processing of sample material. Additionally, jaw material is chosen to fit costumer requirements. Possible jaw materials include manganese steel, stainless steel and tungsten carbide.
