What are the components of a mobile jaw crusher?

As a device that integrates crushing and movement, the core components of a mobile jaw crusher usually include the following modules, which work together to achieve efficient crushing and flexible movement:

1、Crusher (jaw crusher)

Jaw plate system: including fixed jaw and movable jaw. The movable jaw is driven by the eccentric shaft to swing periodically, forming a crushing chamber with the fixed jaw to squeeze and crush the material.

Eccentric shaft and bearing: As the core of power transmission, it bears huge torque and impact load and needs to be made of high-strength materials (such as alloy steel).

Adjustment device: adjust the size of the discharge port through wedges, pads or hydraulic systems to control the particle size of the discharge.

Flywheel: Store energy and balance load fluctuations to ensure smooth operation of the equipment.

2、Mobile chassis

Frame: High-strength steel structure, carrying the crusher and other components, must have anti-fatigue and impact resistance.

Travel mechanism:

Tire type: equipped with tires, axles, and suspension systems, suitable for short-distance transfers or flat roads.

Crawler type: adopts crawler chassis, driven by hydraulic motor, adapting to complex terrain (such as mines, muddy sites).
Power system:
Engine: Diesel engine provides power to drive hydraulic system, walking mechanism and crushing host.
Generator set: optional, providing power support for the equipment.

3、Feeding system
Vibrating feeder: evenly transports materials to the crushing chamber to avoid overload or blockage, and improve crushing efficiency.
Feeding hopper: stores materials to be crushed, usually equipped with a grid to prevent large foreign objects from entering.

4、Conveying system
Belt conveyor: transports crushed materials to a designated location (such as screening equipment or stacking area), and some models are equipped with an adjustable angle conveyor belt.

5、Electrical and control system
Control cabinet: integrated electrical components to realize equipment start and stop, parameter adjustment, fault diagnosis and other functions.
Automation system: optional PLC control system to achieve remote monitoring, automatic operation and data recording.

6、Hydraulic and lubrication system
Hydraulic system: drives the crawler to move, adjusts the size of the discharge port, and realizes the folding and unfolding of the equipment (such as crawler models).
Lubrication system: provides lubrication for key components such as eccentric shafts and bearings to reduce wear and extend service life.

7、Protection and safety devices
Protective cover: covers the transmission parts to prevent splashing objects from injuring people.
Overload protection: When the material is too hard or overloaded, the equipment automatically stops to protect the core components.
Emergency stop button: quickly cuts off the power supply to ensure safe operation.

8、Auxiliary components
Dust removal device: reduces dust emissions and improves the working environment.
Noise reduction design: uses sound insulation materials or structures to reduce equipment operating noise.

9、Modular design (some models)
Foldable structure: folds during transportation to reduce space occupied and facilitate long-distance transportation.
Quick installation: quickly unfolds after arrival to shorten the debugging time.
