In fields such as mining, building demolition, and road construction, crushing operations have always been one of the core links. Traditional fixed crushing production lines require advance site planning and foundation construction, which not only involve high initial investment and long cycles but also fail to flexibly meet the needs of scattered raw materials or temporary operations. The emergence of mobile crushers has completely broken this limitation — integrating functions such as crushing, screening, and conveying into one unit, they can move flexibly according to the location of raw materials, realizing the efficient operation mode of "crushing wherever the raw materials are". This has made them one of the mainstream development directions in the field of crushing equipment in recent years.
Structural Features: Adopting heavy-duty truck tires as the traveling device, equipped with a hydraulic auxiliary steering system, it can be towed by a tractor or driven independently (some models have independent driving functions). With a traveling speed of 30-50 km/h, it is suitable for road transfer.
Core Advantages: High transfer efficiency, strong adaptability to road surfaces, and no need for professional crawler equipment for transportation; compact design enables operation in narrow spaces (such as urban demolition sites and small mines).
Applicable Scenarios: Construction waste recycling (crushing of concrete blocks and bricks), small and medium-sized mining operations (primary crushing of limestone and granite), and aggregate processing in road construction (crushing of recycled asphalt pavement materials).
Structural Features: Using a crawler chassis and equipped with a hydraulic drive system, it has a large ground contact area and low pressure, allowing it to travel on complex terrains such as muddy land, mountains, and steep slopes. Some models have a 360° in-situ rotation function.
Core Advantages: Excellent terrain adaptability, capable of reaching remote mining areas or field operation sites; high stability, enabling normal operation on sites with a slope of less than 15°, suitable for heavy-duty crushing tasks.
Applicable Scenarios: Large open-pit mines (primary crushing of iron ore and copper ore), water conservancy projects (crushing of dredged stones in rivers), and mountain resource development (crushing of quartzite and marble).
Structural Features: Composed of multiple independent mobile units (e.g., "primary crushing mobile station + secondary/tertiary crushing mobile station + screening mobile station"), connected by conveyor belts between units. It can be flexibly combined according to the hardness of raw materials and required crushing particle size.
Core Advantages: Comprehensive functions, enabling the whole-process operation of "primary crushing - secondary/tertiary crushing - screening - finished product conveying"; modular design facilitates later upgrades (such as adding iron removal devices and dust removal systems) to meet diversified production needs.
Applicable Scenarios: Large-scale sand and gravel aggregate production (requiring finished products of multiple particle sizes), deep processing in mines (one-stop processing from raw ore to high-quality aggregates), and large-scale infrastructure projects (e.g., aggregate supply for high-speed railway and airport construction).
Crawler-type models have a ground contact pressure of only 0.08-0.15 MPa, allowing them to travel on soft ground without getting stuck;
Some models are equipped with "foldable conveyors", which can adjust the conveying angle according to site space to avoid material accumulation;
For high-dust working conditions, sealed crushing chambers and dust removal systems can be added to meet environmental protection requirements.
Intelligent Monitoring: Sensors are used to real-time monitor the speed of the crushing host, bearing temperature, and hydraulic system pressure. Automatic alarms are triggered in case of abnormalities to prevent equipment damage due to overload;
Remote Control: Some high-end models support remote control via mobile APP or computer, allowing operators to adjust crushing parameters (such as feeding volume and crushing gap) in safe areas;
Automatic Screening: The integrated vibrating screening system can automatically classify finished products according to the required particle size, and unqualified materials are returned to the crushing host for secondary crushing to ensure the qualification rate of finished products.
During the crushing process, the built-in iron removal device can separate steel bars with a recovery rate of over 95%;
The particle size of recycled aggregates can be adjusted on demand (e.g., 5-10 mm for plastering mortar and 10-20 mm for concrete bedding) to meet different construction needs.
Emergency Repairs: After roads are destroyed by heavy rains, they can quickly crush surrounding stones to make temporary roadbed fillers, shortening the repair time;
Local Material Utilization: When building roads in remote areas, they can crush local rocks into aggregates, avoiding transportation from other places and reducing infrastructure costs;
Old Road Recycling: Crushed and screened asphalt pavement materials after milling can be reused in asphalt mixture production, realizing "resource recycling".
Raw Material Hardness: For hard ores (such as granite and basalt), a combination of jaw crushing host (primary crushing) and cone crushing host (secondary/tertiary crushing) is required; for materials with low hardness (such as limestone and construction waste), impact or impact-type crushing hosts can be selected for higher crushing efficiency.
Production Demand: For small-scale operations (e.g., less than 500 tons per day), a single mobile crusher is optional; for large-scale operations (e.g., more than 1,000 tons per day), a combined crushing station is needed to achieve "multi-machine collaboration".
Site Conditions: Tire-type models are suitable for operations in cities or near highways (convenient for transfer); crawler-type models are suitable for mountainous or muddy sites (strong terrain adaptability).
Power System: For diesel-driven models, regularly check the engine oil, coolant, and fuel filter to prevent engine overheating during high-load operations; for electric-driven models, check the insulation of cables to prevent short circuits in rainy weather.
Crushing System: Regularly check the wear of crushing tooth plates and liners (e.g., jaw plates of jaw crushers and blow bars of impact crushers). Replace them in time when wear exceeds the limit to avoid substandard crushing particle size; at the same time, keep the crushing chamber clean to prevent material blockage.
Travel System: For tire-type models, check tire pressure and wear, and avoid overloaded driving; for crawler-type models, regularly clean sediment and stones in the crawler, and lubricate the crawler chain to prevent rust or jamming.
Conduct a "comprehensive inspection" once a year, focusing on checking the hydraulic system (sealing of oil cylinders and pipelines), bearing clearance, and electrical control system (sensitivity of sensors and controllers);
Choose a dry site for storage. For tire-type models, use brackets to support the tires to avoid deformation due to long-term pressure; for crawler-type models, apply anti-rust oil and cover with dust-proof covers;
Operators should receive professional training to avoid equipment damage caused by improper operation (such as excessive feeding volume or shutting down without emptying the crushing chamber).
