A mobile crushing and screening unit, as the name suggests, integrates a vibrating feeder, primary crusher, secondary and secondary crusher, and vibrating screen into a single tire-mounted mobile carriage. A complete mobile crushing unit comprises: a large-capacity feed hopper, a heavy-duty vibrating feeder, a primary crusher, a secondary and secondary crusher with multi-layer vibrating screens, multiple built-in conveyor belts, a tire-mounted carriage, a hydraulic support system, and an integrated electrical control platform. It highly condenses the multiple pieces of equipment, multiple conveyor belts, and multiple civil engineering foundations of a traditional stationary crushing production line into a single mobile carriage, truly a “mobile crushing workshop.”
Its workflow is clear and efficient: materials are fed into a large-capacity hopper by an excavator or loader, and then evenly conveyed to the primary crusher by a vibrating feeder, completing the first stage of crushing. The crushed material is then transferred by an internal conveyor belt to the secondary crusher for fine crushing. The crushed material is then conveyed to a multi-layer vibrating screen for precise grading and screening. Oversized material can be returned to the secondary crusher via a return system for further crushing (forming a closed-loop cycle to ensure a high finished product qualification rate). Undersized qualified products are output via multiple finished product conveyors, achieving simultaneous production of multiple specifications.
The four-unit mobile crusher has a clear technical positioning, designed specifically for small-to-medium production projects, site-constrained scenarios, and operations requiring rapid relocation. It is an integrated solution combining primary, secondary, and fine crushing with screening. It is highly adaptable, especially suitable for processing medium-hardness materials such as construction waste, limestone, and coal gangue, and is widely used in sand and gravel processing and construction waste resource utilization.
This is the core advantage of the mobile crushing and screening system. It condenses the operations that traditional crushing and screening processes require 4-5 independent machines, tens of meters of conveyor belts, and multiple concrete foundations into a single mobile truck. Only one four-unit mobile truck needs to be deployed on-site to complete the entire process from raw material feeding to the production of multi-specification finished aggregates, significantly simplifying equipment procurement, reducing on-site management difficulties, minimizing personnel costs, and improving overall operational efficiency.
The equipment features a tire-mounted trailer design, allowing for rapid towing to new work sites by a tractor unit, making relocation convenient and efficient. During transport, all functional modules can be folded and secured, strictly adhering to road transport standards without requiring additional disassembly. Upon arrival at the site, the modules quickly unfold via a hydraulic system, with the support legs providing stable positioning; once powered on, production can begin immediately. This “tow-and-go, stop-and-start” characteristic makes it an ideal choice for the rental market and multi-site rotation operations, effectively reducing relocation time and costs.
The footprint of the vehicle in its working state is much smaller than that of a fixed production line with the same capacity, which has an irreplaceable advantage for scenarios with limited space—such as urban construction waste disposal sites, narrow material yards in mountainous areas, and operations inside factories. At the same time, the equipment can be flexibly deployed within the direct working radius of excavators or loaders, minimizing material handling distances and further improving operational continuity.
Compared to traditional fixed production lines, the four-unit mobile production line eliminates significant costs associated with civil engineering foundation construction, steel structure installation, and the procurement of additional conveyor belts, resulting in a substantial reduction in initial investment costs. Furthermore, its rapid deployment and flexible relocation capabilities allow investors to quickly seize market opportunities, shorten the production cycle, and achieve rapid capital recovery. For small and medium-sized investors, it represents a low-cost, high-value entry point into the sand and gravel processing and construction waste recycling industry.
By flexibly adjusting the type of medium and fine crushing unit (impact crusher or cone crusher) and the screen specifications of the vibrating screen, the four-unit mobile crusher can produce various specifications of finished aggregates as needed, such as 12mm gravel, 13mm gravel, 05mm gravel, and manufactured sand, to suit different application scenarios. Whether supplying concrete mixing plants, road base paving, or other engineering material needs, it can easily meet them, demonstrating extremely strong market adaptability.
The equipment is equipped with an integrated electrical control platform and adopts an intelligent control design. The operation process is simple and easy to understand, and no professional technicians are required to get started quickly. The layout of each core module is reasonable, the maintenance channel is convenient, and daily maintenance and fault diagnosis are efficient, which greatly reduces operation and maintenance costs and downtime losses, and ensures long-term stable operation of the equipment.
