Mobile Jaw Crusher

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.

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.

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.

Advantageous of CHUNLEI Machinery Mobile Jaw Crusher

• Integrated unit. Direct operation eliminates the need for complex infrastructure installation and labor costs.
• Suitable for coarse, medium, and fine crushing or sand making of hard rocks and minerals in any harsh environment.
• Ship-shaped steel frame structure, low chassis, lightweight, and well-controlled volume. Small turning radius, highly maneuverable, and stylish design to meet customer needs.
• Hydraulic lifting of the feed guard plate facilitates loading and unloading, convenient fixing, and stable reliability.
• Graded double-layer structure of the feed guard plate provides the prerequisite for customized widening.
• Controllable height adjustment and folding/tilting of the belt conveyor; automatic lifting and adjustment of the magnetic separator.
• Compared with stationary crushing plants, the mobility of mobile crushing plants reduces transportation costs and improves efficiency, making them ideal for remote areas.
