What is Mobile Jaw Crusher?

The mobile jaw crusher adopts an integrated modular design, combining a vibrating feeder, a high-combination-ratio jaw crusher, and a foldable belt conveyor onto a single tracked/wheeled chassis. Its processing capacity ranges from 85 to 650 tons per hour, capable of handling a variety of materials from medium-hardness rock to construction waste.

Its core advantage lies in its fully hydraulic drive and remote control, enabling “on-demand crushing”—requiring no concrete foundation pouring, no external belt conveyor, and no on-site hoisting. A single unit can complete the entire process of feeding, crushing, screening (optional), and discharging.

Compared to stationary crushing lines, it saves approximately 60% of on-site preparation time and 30% of transportation costs, making it particularly suitable for urban construction waste crushing and small- to medium-sized mining operations.

What are its real advantages over a stationary jaw crusher?

Unlike stationary jaw crushers, a mobile jaw crusher constitutes a self-contained production line that can be put into immediate operation simply by connecting it to a power supply. This dynamic, close-range operational mode eliminates the need for secondary material handling, thereby ensuring the synchronization of the crushing process with the mining operations.

Working Principle of Mobile Jaw Crusher

The material flow consists of three steps:

• Uniform Feeding: A vibrating feeder continuously feeds raw materials into the jaw crusher, preventing idling or blockage.
• Primary Crushing: The jaw crusher breaks large stones into medium-sized particles (typically 60-200mm).
• Screening and Recycling: A circular vibrating screen divides the crushed material into three parts:
• Qualified Finished Product: Stacked via the main conveyor.
• Oversized Pieces: Returned to the jaw crusher via a return belt for further crushing (closed-loop circulation).
• Fine Powder/Soil: Discharged from the side outlet, minimizing interference with subsequent crushing operations.

Furthermore, for applications where particle size requirements are not high but maximum capacity is needed (such as roadbed filling), the vibrating screen of the tire-mounted mobile crushing station can be removed, and the material is discharged immediately after passing through the jaw crusher. This modular, quick-release design allows customers to simply loosen the bolts of the vibrating screen module and lift it off entirely. The tire chassis allows for relocation using a regular truck, eliminating the need for a low-bed trailer and saving on transportation permit fees.

Why do many mine owners prioritize mobile jaw crushers when selecting primary crushing equipment?

This preference stems not merely from the jaw crusher’s reliable performance, but—more importantly—from how its unique operating principle aligns perfectly with the demands of mobile operations. Unlike impact or cone crushers, the jaw crusher does not require precise control over feed particle size; instead, it achieves material reduction through the compressive force generated between a stationary jaw plate and a movable jaw plate. This specific characteristic offers two key advantages for mobile applications:

• Low Speed ​​and High Torque—enabling the efficient crushing of hard, highly abrasive rocks (such as granite, basalt, and iron ore). Even when feed sizes fluctuate significantly—ranging from 300 mm to 800 mm—the equipment maintains smooth operation without jamming or stalling.
• Short Stroke and High Amplitude—meaning the movable jaw plate does not require extensive reciprocating motion. This effectively reduces the overall weight of the machine, allowing it to be easily mounted on crawler or wheeled chassis for flexible mobility.

Mobile jaw crushers directly process raw ore or construction demolition waste into finished products with particle sizes ranging from 100 mm to 200 mm, thereby fully preparing the material for subsequent cone crushing or screening stages. This is precisely why, among the various types of mobile crushing stations available, over 70% of units continue to select the jaw crusher as their primary core component.

Application of Mobile Jaw Crusher

The mobile crushing station is widely used for crushing and screening minerals, rocks, and other aggregates as well as recycling solid waste:

• Rock crushing: Limestone, granite, basalt, gabbro, pebbles, dolomite, silica sand, talc, quartz, bluestone, etc.
• Mining crushing: Coal, gold ore, iron ore, copper ore, manganese ore, lithium ore, lead and zinc ore, etc.
• Solid waste recycling: Concrete, construction waste, slag, tailings, demolition waste, etc.
• Infrastructure projects: Road construction, aggregate production, railway development, airport expansion, etc.

Mobile Jaw Crusher FAQ

Q: What is a mobile jaw crusher used for?
A: It is used for primary crushing of hard rocks, demolition concrete, and mining ore directly at the job site.

Q: Can a mobile jaw crusher crush concrete with rebar?
A: Yes, most models can crush concrete with rebar. A magnetic separator removes the steel after crushing.

Q: How much does a mobile jaw crusher cost?
A: Prices range from $80,000 for small units to over $500,000 for large, tracked models. Contact us for a quote.

Q: What is the difference between a mobile jaw crusher and a portable jaw crusher?
A: Usually no difference – “mobile” and “portable” both mean the crusher is mounted on tracks or wheels.

Q: Do I need a permit to operate a mobile jaw crusher on site?
A: It depends on your local regulations. Many sites need a dust/noise permit. Check with your city or county first.
