Ⅰ. Positioning & Core Design Concept
The MST-Y440ERS is a high-spec large scale mobile cone crusher independently developed by MST. It addresses two major pain points in the aggregate industry: tightening environmental regulations and high operating costs of diesel-powered equipment. Abandoning traditional diesel power, it runs on grid electricity to eliminate exhaust pollution at source.
This machine is not simply a diesel engine replaced by an electric motor. Its mainframe structure, hydraulic system, sensor monitoring and electrical protection are fully recalibrated as an integrated whole. It is suitable for continuous crushing of high-hardness materials such as granite, basalt and iron ore, and is built for fixed quarries and large aggregate production lines with infrequent relocation.
Ⅱ. Green Fully-Electric Power System
1.Powered by external industrial grid supply with no diesel exhaust emissions. Equipped with chamber airflow balance dust suppression structure to reduce reliance on water spray dust control. Dust and noise levels meet environmental standards for suburban mining areas and lower the risk of shutdowns triggered by environmental inspections.
2.Fitted with separate energy consumption acquisition modules to independently record power use of the main crusher, conveyors and hydraulic system. It automatically generates energy consumption reports per tonne of material. It features intelligent no-load sleep function: when material flow stops, the system automatically reduces output to cut idle power consumption, greatly lowering electricity expenses over long-term operation.
3.Electrical cabinets feature high-grade dustproof and waterproof protection, with multi-stage circuit protection. It adapts to open-air mining environments with heavy dust and large day-night temperature swings and prevents electrical short-circuit faults.
Ⅲ. Intelligent Sensing & Predictive Health Monitoring System
1.Multi-point vibration spectrum sensors are installed on the main shaft frame, reducer and chassis to continuously collect operational vibration data. Early risks including bearing wear, loose bolts and asymmetric liner wear inside the crushing chamber can be detected in advance, enabling predictive maintenance and reducing unplanned downtime.
2.Built-in industrial data gateway supports connection to the central control platform of the full aggregate production line, remotely uploading throughput, load, energy consumption and alarm logs. Local high-capacity storage ensures operational data is retained during network outages and automatically synchronised once connectivity resumes.
3.Equipped with an adaptive dynamic load module. When the hardness or particle size of incoming material fluctuates, the system automatically adjusts buffer protection thresholds to avoid frequent shutdowns and guarantee continuous and stable production.

Ⅳ. Main Technical Specifications of large scale mobile cone crusher
Ⅴ. Inspection Procedure During Shutdown
1.Before entering the crushing chamber for maintenance, lock the hydraulic system and implement lockout-tagout safety procedures. Confirm complete power cut-off to prevent accidental startup.
2.Fully inspect wear conditions of the main shaft and transmission pairs, assess bearing status, and judge remaining service life of components with reference to vibration spectrum health reports.
3.Inspect fasteners related to the machine’s centre of gravity to eliminate bolt loosening risks caused by long-term impact. Maintain waste oil collection pipelines and oil pans and clean precipitated oil sludge.
4.Verify integrity of reserved expansion interfaces, check authority settings on the HMI terminal and clear redundant system alarm records.
Ⅵ. Operating & Maintenance Taboos and Precautions
1.Never start production with protective doors open or safety interlocks disabled.
2.Prolonged overloading or uneven feeding is prohibited, as this will cause abnormal one-sided chamber wear and shorten service life of bushings and the main shaft.
3.For low-temperature winter operation, fully preheat the lubrication system before startup. At sites with limited water supply, prioritise airflow-balance dust suppression to avoid component damage caused by frozen water pipelines.
4.Operation and maintenance personnel use graded accounts. Ordinary operators are not permitted to arbitrarily modify core parameters including mainframe protection and adaptive load settings.
Ⅶ. Frequently Asked Questions
Q: How much more expensive is the electric short-head cone compared to the diesel version? A: The price difference depends on your selected electrical configuration. The electric version generally carries a higher purchase price, but it can save more than CNY 100,000 per year on energy costs. The extra investment can be recovered within two to three years, delivering lower operating costs thereafter.
Q: Will material jamming occur if grid power fails? A: Our electric control system is fitted with power-failure protection and hydraulic accumulators. The hydraulic system can still adjust the discharge gap during blackouts to facilitate cavity clearing. For areas with frequent power cuts, we recommend equipping an emergency generator set.
Q: How fine can the discharge size be adjusted? A: The minimum discharge gap of this short-head cone can be set to several millimetres. The exact finished particle size depends on your required product specification and rock hardness. We will calibrate the machine according to your requirements during commissioning.
The MST-Y440ERS electric crawler-mounted cone crusher integrates green fully-electric power, intelligent predictive monitoring, optimised mechanical structure and a complete after-sales service system. Against the backdrop of stricter environmental rules and energy reduction requirements across the aggregate industry, this model is an excellent option for new large hard-rock aggregate projects and replacement of outdated crushing
