Small 250KW Multi Cylinder Cone Crusher With Integrated Hydraulic System


Description

This series of multi-cylinder hydraulic cone crushers adopts a four-in-one technical architecture of mechanical-hydraulic-electrical control-intelligent control, integrating the modular design concept of the German Industry 4.0 standard.

In terms of adaptability to working conditions, the equipment uses a combination of a curved crushing wall made of Swedish SSAB wear-resistant steel and a manganese steel liner, combined with a fully enclosed dustproof structure, to effectively cope with the high abrasive conditions in the crushing process of river pebbles. Actual production data shows that when processing granite with a Mohs hardness of 7.2, the processing capacity of a single machine can reach 800t/h, which reduces energy consumption by 23% compared to traditional equipment and extends the service life of the liner by 40%.

Technical Details

Product Advantage

1. Fixed-axis heavy-duty structure design (VS peer cantilever spindle structure)
Adopting a fully constrained fixed-axis topology architecture, the spindle and the frame form a statically determinate support system. Compared with the traditional cantilever spindle structure, the axial stiffness is increased by 45%, and the dynamic load bearing capacity reaches 3200kN/m² (the industry average is 2400kN/m²). Combined with the high-strength alloy steel casting matrix optimized by finite element topology, the volume is reduced by 18%, and the fatigue life of the whole machine exceeds 30,000 hours (benchmarked against 28,000 hours for international brands). The standard floating anti-seismic base reduces the foundation cost by 37% compared with the traditional rigid installation, and meets the ASME B5.54 anti-seismic standard.

2. Laminated crushing dynamics optimization (VS single particle crushing mode)
The four-dimensional crushing cavity is constructed based on EDEM discrete element simulation, and the directional energy transfer is achieved through particle flow field reorganization technology. Actual working data show that the proportion of 3-25mm intermediate particles in the finished granite crushing products is 78% (the industry average is 65%), and the needle-like rate is stable below 6.8% (the industry standard is ≤15%). With the multi-objective optimization algorithm, the unit steel consumption of the liner is reduced to 0.18kg/t (0.25-0.35kg/t for similar equipment), which is particularly suitable for the aggregate grading control scenario of commercial concrete stations.

3. Intelligent temperature control lubrication system (VS traditional water cooling system)
Integrated three-stage filtration precision oil circuit (β≥200), using aviation-grade titanium alloy plate air cooler (heat exchange efficiency ≥92%), completely eliminate the common oil-water emulsification problem of water cooling system. The measured oil temperature fluctuation of 240h continuous operation is ≤±3℃ (the industry allows ±8℃), and with non-contact magnetic fluid seal (leakage rate <0.1ml/h), it achieves 8000 hours of maintenance-free cycle (5000 hours for peers). Passed ISO 4406-1999 cleanliness certification.

4. Filler-free quick-change liner system (VS epoxy resin filled type)
The cone self-locking device is developed based on the DIN 7182 standard, and the bowl-shaped bearing mounting surface is precisely ground by a five-axis linkage machining center (flatness ≤ 0.02mm). The liner replacement operation time is shortened to 35 minutes (the traditional process takes 2-3 hours), and there is no need for a curing waiting period. The patented wedge preload structure increases the uniformity of contact stress distribution by 60%, and is successfully applied to the continuous crushing system of the Baihetan Hydropower Station (the daily replacement frequency is reduced by 83%).

5. Heavy-duty transmission assembly (VS rolling bearing solution)
Innovatively adopts a tin bronze-based self-lubricating bearing (PV value of 3.5MPa·m/s) + Klingenberg spiral bevel gear (AGMA 12 grade accuracy) transmission combination. Under the working condition of dust concentration of 200mg/m³, the transmission system noise is ≤85dB(A) (national standard ≤95dB(A)), and the rated torque transmission efficiency reaches 98.2% (94-96% of the same rolling bearing solution). Verified by the Chinese Academy of Mechanical Sciences, the life span under the impact load spectrum reaches 10^8 cycles (industry benchmark 7.5×10^7 times).

6. Hydraulic safety redundancy system (VS single-stage buffer solution)
Configured with a dual-channel overload protection system consisting of φ80mm high-pressure hose (burst pressure 55MPa) + accumulator group (total volume 120L), the response time is ≤80ms (traditional system 120-150ms). Through AMESim simulation verification, it can absorb instantaneous impact energy of up to 18kJ (similar equipment 12-15kJ), and has been successfully applied to the Panxi vanadium-titanium magnetite superhard rock crushing line (annual unplanned downtime reduced by 62%).

7. Modular installation platform (VS traditional concrete foundation)
The elastic installation system developed based on the VDI 2230 standard contains patented damping pads (damping ratio ξ≥0.15) and quick positioning pins (repeat positioning accuracy ±0.5mm). The on-site installation period is shortened to 3 working days (7-10 days for traditional methods), and the foundation bearing requirement is reduced to 150kPa (the industry standard is 250kPa). It has been successfully applied to Southeast Asian island reclamation projects (100% installation qualification rate in areas with complex sea conditions)
