Tracked Mobile Crushing and Screening Station

The tracked mobile crushing and screening station is the only single-machine solution that integrates the entire aggregate processing flow: vibratory feeding, primary jaw crushing, secondary impact crushing, vibrating screen sorting and automatic return of oversized material — all on a self-contained platform that travels on hydraulic tracks directly to the work face, with no prepared roads, no foundations and no intermediate transport infrastructure. This mobile crushing and screening station eliminates the costly logistics specific to fixed installations or combinations of separate machines.

Compared to a mobile crusher with a single crushing body, the tracked mobile crushing and screening station produces aggregate sorted into multiple fractions in the same work cycle — granite, limestone, quartz, iron ore, recycled concrete or demolition rubble are processed and sorted simultaneously, with no intermediate manual operations and no material transfer between separate machines. The high productivity and the low cost per ton produced make this the choice of quarry operators, infrastructure contractors and recycling operators with medium and large volumes of material to process. Key advantages of the tracked mobile crushing and screening station

• A complete production line in a single machine — the mobile crushing and screening station integrates all stages of the process: controlled feeding, primary crushing, secondary crushing, fraction sorting and automatic return. It eliminates the need to purchase, transport and coordinate 3–4 separate machines for the same result, significantly reducing capital cost and operational complexity.

• Autonomous travel on hydraulic tracks — the hydraulic tracks allow the mobile crushing and screening station to travel over rough, slippery or hard-to-access terrain, with no concrete roads and no transport crane. Relocation to the new work face is performed under its own power, in a short time and with no platform or escort costs.

• Two-stage crushing — the jaw crusher performs the primary crushing (reducing large blocks to processable sizes), while the impact crusher performs the secondary crushing (granulometric finishing). The combination of the two stages produces aggregate with clean edges and a uniform particle size distribution, superior to that obtained from a single crushing stage.

• Vibrating screen with automatic return — the vibrating screen sorts the produced material into distinct fractions and automatically redirects oversized material back into the crushing flow, with no manual intervention. The result is a continuous production cycle, with no material loss and no stoppages for removing rejects.

• Optional: generator set for areas without power — the mobile crushing and screening station can be configured with an integrated generator set for fully autonomous operation in areas without access to the electrical grid or with an unstable supply. Work continues uninterrupted regardless of the energy infrastructure available on site.

• Rapid installation, no foundations — the modular design and compact configuration eliminate the need for foundation works or special site preparation. The mobile crushing and screening station arrives on site and enters production within the same time frame, minimizing the loss of productive days compared to fixed installations.

• Flexible configuration adaptable to the application — the components of the mobile crushing and screening station can be selected according to the type of material to be processed, the required hourly capacity and the desired particle size of the grades, with specialized technical consultancy included through UZINEX.

• 60-month warranty and nationwide technical support — extended coverage for a mobile crushing and screening station in continuous industrial production, with spare parts in stock in Iași and technicians with nationwide coverage.

Operating principle — the mobile crushing and screening station

The tracked mobile crushing and screening station operates as a continuous and automated production line, with five stages integrated into the same mobile frame.

• Vibratory feeding — the excavator or front loader discharges the raw material into the vibratory feeder. The controlled vibration system distributes the material evenly and automatically regulates the feed rate according to the load detected in the primary crusher, preventing overloading and blockages.

• Primary jaw crushing — the jaw crusher reduces large blocks of material to processable sizes. This is the stage with the highest energy consumption and the greatest mechanical stress — the jaw crusher of the mobile crushing and screening station is sized for the feed opening and material class specific to the chosen configuration.

• Secondary crushing with impact crusher — the primary-processed material is conveyed by belt to the impact crusher, which finishes the particle size and produces aggregate with a uniform cubic shape. The impact crusher of the mobile crushing and screening station is adjustable to control the size of the final product before sorting.

• Sorting on the vibrating screen — the vibrating screen separates the crushed material into fractions according to the selected grade sizes. Each fraction is discharged onto its dedicated belt to the finished-product stockpile. The number of fractions produced simultaneously depends on the configuration of the chosen screen.

• Automatic oversize return — material that exceeds the maximum size accepted by the screen is automatically redirected onto the return belt back to the impact crusher, with no manual intervention. The cycle repeats until all the material passes the screen at the desired particle size, eliminating any material loss.

Materials processable with the mobile crushing and screening station

The tracked mobile crushing and screening station is designed to process a wide range of materials, from hard natural rocks to industrial and demolition waste.

Hard natural rocks — granite, basalt, quartz, compact limestone, dolomite — are the reference material for which the jaw crusher and the impact crusher of the mobile crushing and screening station are sized. Granite and basalt, with compressive strengths of 200–300 MPa, are processed efficiently in two stages, producing construction aggregate with clean edges and high strength, suitable for structural concrete, road layers and railways.

Metallic and non-metallic ores — iron ore, copper, coal, bauxite — can be processed with specific configurations of the mobile crushing and screening station, adapted to the hardness and abrasiveness of each type of ore. The mobility on tracks allows the active extraction face to be followed, eliminating the transport of raw ore to a distant fixed installation.

Demolition waste — reinforced concrete, brick, mortar, asphalt — is processed by the mobile crushing and screening station directly at the demolition site, producing recycled aggregate usable on the same site or marketable as secondary construction material. On-site recycling eliminates the cost of transporting inert waste to the landfill and the cost of purchasing new aggregate, with a direct positive impact on the demolition budget.

Medium and large capacity natural stone quarries are the classic application of the tracked mobile crushing and screening station. The mobility at the face allows the extracted material to be processed directly at the extraction site, eliminating the transport of raw rock to a centralized fixed installation. In a quarry with a changing active extraction face, the mobile crushing and screening station relocates under its own power, keeping the internal transport distance to a minimum and the cost per ton at a competitive level.

Large road and rail infrastructure contractors use the mobile crushing and screening station to produce the necessary aggregates directly along the work route — sub-bases, ballast foundations, formation layers. Compared to sourcing aggregates from distant quarries, on-site production reduces material costs and eliminates dependence on external suppliers, with direct control over the quality of the grades produced.

Operators specialized in large-volume industrial and civil demolition integrate the mobile crushing and screening station into the demolition flow for the immediate recovery of inert waste. Demolished reinforced concrete becomes sorted recycled aggregate, salable or reusable on the same site. Rubble becomes fill material. Milled asphalt becomes RAP (Reclaimed Asphalt Pavement) usable in new road layers. Turning waste into resources radically reduces the total cost of demolition and improves the contract margin.

Small and medium-scale mining operations benefit from the energy autonomy offered by the generator set option of the mobile crushing and screening station, which allows installation in areas without access to the electrical grid — geographically isolated or in the early stages of opening the operation, before connection to permanent energy infrastructure. Frequently asked questions about the mobile crushing and screening station

What distinguishes the mobile crushing and screening station from a simple mobile crusher?

A simple mobile crusher performs a single crushing stage and produces material that is not separated into fractions — the operator obtains a mixed aggregate that requires subsequent sorting with other equipment. The tracked mobile crushing and screening station integrates two crushing stages and complete sorting in the same cycle, delivering the final grade fractions directly to the finished-product stockpile. The practical difference: one machine versus 3–4, a single operation versus several, a significantly lower cost per ton at high volumes. What type of terrain do the hydraulic tracks work on?

The hydraulic tracks of the mobile crushing and screening station allow travel over rough, muddy, rocky or moderately sloped terrain — types of terrain inaccessible to wheeled machines and impossible to serve with transport platforms without costly preparation. No concrete or compacted access roads are required. The maximum travel slope and the ground pressure specific to the chosen configuration are confirmed by UZINEX engineers at quotation. How many grade fractions does the mobile crushing and screening station produce simultaneously?

The number of fractions produced simultaneously depends on the configuration of the vibrating screen — the number of decks and the screen mesh sizes. Standard configurations produce 2–4 simultaneous fractions (e.g.: 0–10 mm, 10–25 mm, 25–63 mm, 63+ mm return). Special configurations with multi-deck screens can produce additional fractions. UZINEX engineers size the screen according to the grades required by your application. How long does it take to relocate the mobile crushing and screening station to a new work face?

Relocating the tracked mobile crushing and screening station to a new work face within the same site (quarry, demolition site) is performed under its own hydraulic power, with no transport platform, in minutes or hours depending on the distance and terrain. Relocation to a new site (another site, another quarry) requires transport on a platform — the duration depends on the footprint of the chosen configuration. UZINEX engineers specify the transport footprint and the platform requirements at quotation. Is a foundation or special preparation of the terrain required?

No. The tracked mobile crushing and screening station does not require foundations, concrete slabs or special preparation of the terrain. It arrives on site, positions itself on the available ground and enters production immediately. This is one of the fundamental differences from fixed crushing and screening installations, which require preparatory civil works of 2–6 weeks before the first ton is produced. Is the mobile crushing and screening station eligible for EU funds or public procurement?

Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for projects with EU funds and public procurement through SEAP/SICAP. The complete technical documentation required for tender files is provided on request. Leasing and financing options available on the UZINEX credit and leasing page .
