Ⅰ. Product Introduction
MST-YA300HRS tracked cone crusher is a high-spec mobile secondary crushing unit designed for medium and large-scale hard rock crushing conditions. It features a maximum feed size of 220 mm and throughput of 100–320 tonnes per hour. Equipped with a 250 kW variable-frequency soft-start main motor and adopting laminated crushing technology, it produces premium low-flakiness aggregate with excellent particle shape. The machine comes with automatic central lubrication, an independent hydraulic cooling system, IP54 dustproof electric control, built-in fully automatic one-click cavity clearing and overload protection. The heavy-duty hydraulic tracked undercarriage travels autonomously on uneven mine pits; no concrete foundation is required for fast relocation.
Ⅱ. Core Product Features
Integrated & Pre-assembled Design
1.The machine is pre-fitted with a central lubrication station that automatically supplies grease to main bearings on a timed schedule. Daily manual greasing is no longer required, reducing equipment damage caused by missed maintenance.
2.The crushing mainframe, conveyor and power unit are modularly pre-assembled. Full no-load linkage testing is completed before factory delivery. After arrival on site, the machine can be put into production shortly once connected to power.
3.Integrated anti-spill rock guards and optimised sealing around the crushing zone reduce stone splashing, improve site safety and minimise wear on surrounding equipment.

Reliable Hydraulic System Design
1.Independent cooling oil circuit continuously lowers hydraulic oil temperature during long-duration high-temperature continuous operation. It prevents rapid hydraulic oil ageing and seal failure caused by high heat, suitable for long shifts in mines during summer.
2.Multi-stage filtration in the oil circuit traps contaminants, protecting hydraulic valve blocks and cylinders, cutting hydraulic failures and extending service life of hydraulic components.
3.Accumulator buffer protection absorbs impact loads under fluctuating feed flow, stabilising the discharge gap and reducing variation in finished product particle size.
Vibration Damping & Machine Stabilisation System
1.Heavy-duty composite shock absorbers are mounted on the mainframe base to absorb strong impact vibrations generated during crushing. This reduces vibration transfer to the tracked chassis and protects the frame and electrical components.
2.It mitigates bolt loosening induced by vibration, lowers routine inspection and tightening workload, and extends service life of frame welds.
Electrical & Environmental Protection
1.The main electric cabinet is rated IP54 for dust and water resistance, reducing short circuits and component fouling in dusty mines with morning/evening humidity.
2.Overload history recording stores fault codes and operation logs, enabling fast remote troubleshooting by after-sales teams and shortening fault diagnosis time.
3.Independent emergency stop circuit with multiple stop points, local plus remote dual emergency stop channels, complying with mine safety regulations.
Ⅲ. Advantages in Spare Parts, Operation & Maintainability
1.Core wear parts have strong market commonality. Lead time for spare parts stock is short; no custom exclusive components are required, cutting waiting time for spare parts during shutdowns.
2.Wide service access passages are reserved for maintenance. Most inspection work can be completed standing on service platforms without extensive temporary scaffolding.
3.Quick-connect fittings are adopted for all hydraulic pipelines. For split transportation or component overhaul, pipeline disassembly and reassembly is faster and reduces oil leakage contamination.

Ⅴ. Application Scenarios
The MST-YA300HRS tracked cone crusher is developed for medium and large mobile hard rock crushing projects, supporting on-site crushing to minimise material haulage.
1.Open-pit hard rock quarries: Secondary crushing for granite and basalt mines. It moves synchronously behind jaw crushers and produces premium 25–70 mm aggregate for high-standard infrastructure such as highways and high-speed railways.
2.Underground / open-pit metal mines: Secondary crushing for iron ore, quartzite and diabase. Mobile and flexible, it can be relocated as mining faces advance.
3.Hard construction waste recycling projects: Process reinforced concrete construction debris. Recycled aggregate after crushing is used for road subgrade backfill and precast component raw materials. Optional magnetic separator removes steel rebar.
4.Temporary site mobile crushing for construction projects: Process tunnel muck and slope rock directly on-site for highway, tunnel and water conservancy works. Produce aggregate for self-use locally and eliminate costs for haulage and purchasing external stone.
5.Mobile processing for small sand & aggregate plants: Rotate operation across multiple sites. Fast relocation by flatbed trailer without concrete foundation. Commissioned quickly after arrival, ideal for scattered multi-location mining projects.
Ⅵ. Frequently Asked Questions
Q: How much more expensive is the hybrid version than the pure diesel version? How long is the payback period? A: The price difference depends on selected diesel engine power and grid access conditions. Assuming 10 operating hours per day and fuel price of 7 CNY per litre, the hybrid unit can save roughly 100,000 to 150,000 CNY in fuel cost per year. The extra investment is typically recovered within 2–3 years, after which all savings are net profit.
