Mobile jaw crusher with a weld-free modular structure (no-welding frame), the self-contained crushing machine chosen by demolition, quarry and infrastructure contractors who need industrial processing capacity directly at the material source, without the costs of transporting inert waste to fixed stations. Compared with classic welded-frame jaw crushers, this mobile jaw crusher delivers roughly 25% higher productivity thanks to the optimised crushing chamber angle and improved nip angle, which increase the fragmentation rate per cycle without increasing energy consumption.
Hydraulic adjustment of the discharge opening allows precise control of the particle size of the final product directly from the control panel or via the wireless remote, without stopping the machine and without manual mechanical intervention. The vibrating feed hopper of approximately 7 m³, with steel springs and an automatically controlled vibration system, takes in large blocks of material and feeds them uniformly toward the crushing chamber, eliminating clogging and ensuring continuous flow. This mobile jaw crusher is the right equipment when the daily volume of material processed, the distance to fixed stations and the cost of transport justify the investment in a self-contained mobile solution.
Key advantages of the mobile jaw crusher
• Weld-free modular frame: strength and easy transport. The no-welding frame is mechanically assembled with precision bolted joints, with no thermal weakening points specific to welds. Disassembling the modules for transport on standard trailers and reassembling them at the destination is done quickly, without large specialised lifting equipment.
• 25% higher productivity than standard-angle crushers: the crushing chamber with a large inclination angle and optimised nip angle increase the amount of material fragmented per cycle. For the same input volume, this mobile jaw crusher produces a quarter more aggregate than classic configurations, proportionally reducing the cost per tonne processed.
• Hydraulic adjustment of the discharge opening: the particle size of the final product is set hydraulically, from the operator's cab or via wireless remote, without stopping production. Switching from one grade to another (e.g. from 0–50 mm to 0–80 mm) is done in seconds, adapting the machine to the site's current requirements.
“Hydraulic adjustment of the discharge opening: the grain size of the final product is adjusted hydraulically, from the operator's cab or through a wireless remote control.”
• Vibrating feed hopper ~7 m³ with steel springs: the hopper capacity allows loading with a medium-sized excavator bucket without interrupting the feed to the crushing chamber. The automatically controlled vibration system adjusts the feed rate according to the load detected in the crushing chamber, preventing jams.
• Wireless remote control via advanced PLC. The operator supervises and controls all machine functions from a safe distance from the crushing zone: start/stop, jaw opening adjustment, conveyor belt control, parameter monitoring. Reducing the required staff to 1 operator and increasing safety are direct consequences of this fully automated mobile jaw crusher.
• Stock and bypass conveyor belts, some foldable: the belts for discharging the produced aggregate and the bypass belts for oversized material are configurable in length and number according to site requirements. The foldable belts reduce the overall transport dimensions while maintaining the installed working capacity.
• Compact design optimised for fast transfer between sites: the travel autonomy (on tracks or wheels, depending on configuration) and the compact footprint allow the machine to be relocated to new work fronts without high transport costs and without losing productive days.
• 60-month warranty and spare parts in stock at UZINEX: extended coverage for a mobile jaw crusher in continuous production, with critical parts immediately available in Iași.

Contractors demolishing industrial buildings, residential blocks, bridges and viaducts made of reinforced concrete are the main users of this mobile jaw crusher . The volumes of concrete resulting from large-scale demolition (hundreds or thousands of tonnes) are impossible to transport economically to fixed crushing stations without eroding the contract's profit. On-site processing with a mobile jaw crusher turns demolition waste into recycled aggregate usable on the same site as fill, sub-base or levelling material.
Operators of small and medium-scale stone quarries and mining use the mobile jaw crusher as the first crushing stage (primary crusher) to reduce large extracted blocks to sizes processable by secondary crushers. The machine's mobility allows it to follow the active extraction front without fixed infrastructure costs, a flexibility impossible with fixed crushing plants.

Autonomous mobile jaw crusher
Road and rail infrastructure works with large volumes of inert material to process (rock cuttings, excavations in hard ground, demolition of old concrete structures) benefit from the autonomy of this mobile jaw crusher, which moves along the work front and processes the material in real time, eliminating intermediate storage and additional transport.
How the mobile jaw crusher works: workflow
• Hopper feeding: the excavator or front loader unloads blocks of concrete, stone or asphalt into the vibrating feed hopper (~7 m³). The vibration system with steel springs takes up the material and conveys it in a controlled manner toward the crushing chamber.
• Pre-screening (optional): the feed grizzly separates the fine fractions that can bypass the crushing chamber directly onto the discharge belt, reducing jaw wear and increasing efficiency.
• Primary crushing in the jaw chamber: the moving jaw and the fixed jaw compress and fragment the material through an eccentric motion. The optimised chamber angle increases the fragmentation force per cycle compared with standard configurations, delivering the ~25% productivity gain.
• Real-time particle size adjustment: the operator hydraulically adjusts the discharge opening from the wireless remote to obtain the desired final aggregate size, without stopping production.
• Discharge onto conveyor belts: the crushed aggregate is discharged onto the stock belt to the finished-product stockpile. Oversized material that does not pass through the discharge opening is directed onto the bypass belt for re-feeding or separate storage.
• PLC monitoring and control. All operating parameters are continuously monitored by the PLC system: motor load, temperature, feed rate. Automatic alarms and protective shutdowns prevent damage in case of overload or a metallic object in the chamber.
• Fast relocation to the new work front: when a front is completed, the mobile jaw crusher moves autonomously or on a trailer to the new location and resumes production in minimum time.
Frequently asked questions about the mobile jaw crusher
What is the difference between a mobile jaw crusher and a fixed crusher?
A mobile jaw crusher is a self-contained machine that moves to the material source (on site, in the quarry or at the demolition front) and processes the material directly where it is generated. A fixed crusher requires transporting the raw material to the plant, with high transport and logistics costs. For large volumes and long distances from fixed stations, the mobile jaw crusher is significantly more economical per tonne processed. What is the maximum material size that can enter the hopper?
The maximum size of material pieces accepted into the hopper depends on the size of the crushing chamber's feed opening, a parameter that varies according to the crusher model and configuration. UZINEX engineers confirm this size at the quotation stage, depending on the type and dimensions of the material specific to your application. As a rule, mobile jaw crushers in this class accept blocks of up to 500–800 mm on the long side. Can this mobile jaw crusher process reinforced concrete with rebar?
Yes, mobile jaw crushers are designed to process reinforced concrete. The steel rebar passes through the crushing chamber without causing jams, coming out bent together with the aggregate. A magnetic separator mounted on the discharge belt (optional) can recover the rebar and ferrous fractions for resale. UZINEX engineers recommend the optimal configuration according to the rebar content of the concrete to be processed: free technical consultancy available . How many operators are needed to run the mobile jaw crusher?
The PLC system with wireless control allows this mobile jaw crusher to be operated by a single operator, who supervises and controls all functions from a safe distance from the crushing zone. Compared with crushers without advanced automation, which require 2–3 operators, the reduction to 1 operator produces significant labour cost savings per shift. Is it eligible for projects with European funding or public procurement?
Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for projects with EU funds and public procurement. The complete technical documentation required for tender files is provided on request. For purchases through SEAP/SICAP, the product can be added directly from the product page. Leasing options available on the credit and leasing page . How does this mobile jaw crusher compare with other crushers in the UZINEX catalogue?
