UH320 mobile cone crusher is the star product in the wheeled crushing station series, specially designed for medium and fine crushing operations. Its core crushing unit adopts CH430 hydraulic cone crusher, equipped with high-efficiency crushing chamber, which can adapt to materials of different hardness and ensure stable output of high-quality aggregates. The whole machine adopts wheeled chassis, which is flexible to transfer and does not require additional transportation equipment. It is suitable for switching between multiple operation points. Sandvik Automine or My Fleet remote monitoring is standard, which monitors the equipment operation status, output and energy consumption in real time to optimize production efficiency. The discharge port is hydraulically adjusted, and the pressure is automatically released when encountering hard objects or overload to protect the core components of the equipment. Low noise and low emissions: It meets environmental protection standards and is suitable for urban construction waste treatment and mining areas with strict environmental protection requirements.
Advantages
High-efficiency laminated crushing technology improves production and finished product quality
UH320 uses the interparticle crushing principle to achieve efficient crushing through mutual extrusion and grinding between materials. Compared with traditional impact crushing: it can reach 350 tons/hour in granite crushing (equipment of the same specification is generally ≤280 tons); the proportion of cubic particles exceeds 85% (traditional equipment is about 60-70%), which significantly improves the compressive strength of aggregates and is particularly suitable for high-grade concrete ingredients; the over-crushing rate is reduced by 30%, and the proportion of 0-5mm powder is controlled within 8% (the industry average is 15%), reducing resource waste.
Intelligent hydraulic system for precise control and protection
Equipped with a fully automatic hydraulic control module, it integrates three core functions: real-time adjustment of the discharge port: hydraulic adjustment within the range of 6-45mm, response time <30 seconds (mechanical type requires manual operation when stopping the machine); when encountering unbreakable objects (such as iron blocks), the hydraulic cylinder automatically releases pressure to avoid spindle breakage (repair costs can be reduced by 500,000+/time); dynamic compensation of crushing force makes the liner wear evenly and extends its life to 800-1000 hours (industry average 500 hours).
Modular wheel design, extremely flexible transfer capability
For the needs of multiple operation points, UH320 adopts a wheeled mobile chassis + quick docking system: transfer efficiency is increased by 3 times: it only takes 1.5 hours from transportation status to production (crawler type takes 3-4 hours); the whole machine weighs 35 tons and can be transported by a standard semi-trailer (compared with crawler type UH440, which requires a low-bed truck); compact size adapts to narrow sites: the working width is only 3 meters, and it can be flexibly turned at the site of urban construction waste treatment.
Multi-power adaptation and low energy consumption design
Dual power options: standard CAT C9.3 diesel engine (159kW), optional 380V external power supply (noise in electric drive mode reduced to 68dB); intelligent power distribution: when the crusher is running at full load, the hydraulic system automatically reduces the frequency, and the comprehensive energy consumption is 15% lower than similar products; the fuel consumption in standby mode is only 5L/h (8L/h in normal mode), which is suitable for intermittent feeding conditions.
Full process automatic control, reducing manual dependence
Integrated Sandvik ASRi intelligent control system to achieve: automatic compensation of liner wear: through real-time monitoring of the main shaft position, dynamic adjustment of the discharge port, to ensure the stability of the discharge particle size (fluctuation <±2mm); through the My Fleet platform, you can view 30+ parameters such as bearing temperature and lubricating oil status, and warn of faults in advance (such as automatic alarm when the oil temperature is >75℃); novices can operate independently after 1 day of training, reducing labor costs by 50%.
Double breakthrough in environmental protection and maintenance convenience
Low emission design, diesel engine complies with EU Stage V emission standards, PM emission <0.025g/kWh; automatic oil filling every 8 hours, lubrication point failure rate reduced by 90%; liner replacement takes only 2 hours (traditional design takes 4 hours); hydraulic oil tank and filter are arranged sideways, and maintenance can be performed without climbing.
Working Principle
UH320 mobile cone crusher adopts the principle of interparticle crushing, and crushes materials through the extrusion, shearing and grinding between the moving cone and the fixed cone. The materials are evenly fed into the crushing chamber through the feeder to avoid blockage or partial load. The hydraulic motor drives the eccentric sleeve to rotate, driving the moving cone to do a swinging motion, and the materials are repeatedly squeezed and hit in the crushing chamber. The size of the discharge port is adjusted by the hydraulic system to control the final discharge particle size (such as 0-20mm or 0-45mm). After crushing, the materials are graded by the built-in screening machine (optional), and the qualified materials enter the finished product pile, and the oversized particles return to the crushing chamber for secondary crushing. Control the adjustment of the discharge port, overload protection and the lifting of the moving cone to ensure stable operation. Automatic circulation lubrication reduces friction loss and extends the life of bearings and gears. Driven by a diesel engine or an external power supply, it can adapt to different working environments.

Customer evaluation:
"We compared the equipment of many machinery companies and finally chose UH320 because its hydraulic system is more stable. After two years of operation, even when processing high-silicon granite, the cone liner life can still reach 800 hours, 20% higher than expected."
