Among portable stone crushers, they are mainly divided into two categories according to the movement mode: tire-type mobile crushing station and crawler-type mobile crusher. They have significant differences in mobility, applicable scenarios and cost.
1. Tire-type mobile crushing plant
• Features:
Chassis structure: heavy-duty tires + axles are used, and they need to be towed and moved by a tractor (such as a truck or tractor).
Transfer flexibility: suitable for road transportation, can be quickly transferred over short distances, but requires external power traction.
Applicable terrain: flat hardened roads (such as construction sites and near roads), and poor passability in complex terrain.
Cost: low purchase and maintenance costs, suitable for projects with limited budgets.
• Advantages:
✔ Convenient transportation, in compliance with highway regulations (license can be obtained).
✔ Suitable for short-term projects or operations that require frequent site changes.
• Limitations:
✘ Depends on traction equipment, and has poor passability in muddy and sloping land.
✘ Manual assistance is required to unfold/fold the outriggers, and the preparation time is long.
• Typical applications:
✔ Construction waste recycling, urban demolition projects.
✔ Temporary production of sand and gravel aggregates (such as road construction, small mines).
2. Crawler mobile crusher
• Features:
Chassis structure: Integrated hydraulic crawler drive system, can walk autonomously without a tractor.
Transfer flexibility: remote control or cab control, adapt to rugged terrain (mountains, wetlands, slopes).
Applicable terrain: complex and harsh environment (such as mining areas, swamps, rugged mountains).
Cost: high price, complex maintenance (crawler is easy to wear).
• Advantages:
✔ All-terrain mobility, climbing ability of more than 30°.
✔ High degree of automation, one-button unfolding/folding, saving manpower.
✔ Can be used with GPS positioning to achieve intelligent scheduling.
• Limitations:
✘ Highway transportation requires disassembly or the use of a flatbed truck, which results in high freight costs.
✘ Track maintenance costs are high (such as replacing track shoes and rollers).
• Typical applications:
✔ High-intensity operations such as large mines and quarries.
✔ Disaster relief sites (such as handling building ruins after an earthquake).
3. Comparison summary
| Projects | Tire-type mobile crushing plant | Track-type mobile crusher |
| Moving mode | Requires towing by a tractor | Autonomous crawler |
| Terrain adaptation | Flat hardened road surface | Mountain, mud, slope and other complex terrains |
| Transfer speed | Fast (road transportation) | Slow (need to disassemble or slow off-road) |
| Automation degree | Low (needs manual assistance) | High (remote control/intelligent control) |
| Cost | Low (purchase + maintenance) | High (equipment + maintenance) |
| Applicable scenarios | Short-term projects, urban demolition | Long-term mines, harsh environment operations |
4. Selection recommendations
• Choose tire-type: limited budget, flat site, need for fast transfer (such as road repair team, construction waste treatment).
• Choose crawler-type: complex terrain, high automation requirements, long-term high-intensity operations (such as large quarries).
Some manufacturers also offer a semi-track hybrid design (front wheels and rear tracks), which takes into account both cost and passability and is suitable for medium-difficulty working conditions.
FAQ about portable mobile crushing station (Frequently Asked Questions)
1. What is a portable mobile crushing station?
A portable mobile crushing station is a movable rock/ore crushing equipment, usually mounted on a tire or crawler chassis, which can quickly transfer and perform crushing operations at different work sites. It is suitable for mining, construction waste treatment, road construction, and other fields.
2. What materials can a portable mobile crushing station crush?
It can handle materials of various hardness and types, including:
• Natural ores such as granite, basalt, limestone, etc.
• Construction waste (concrete, bricks, asphalt)
• Industrial waste such as coal gangue and tailings
3. How to choose between tire-type and crawler-type mobile crushing stations?
• Choose tire-type: limited budget, flat site, frequent transfer (such as urban demolition).
• Choose crawler-type: complex terrain, high automation requirements, long-term high-intensity operations (such as mining).
4. What is the production capacity of a portable mobile crushing station?
The capacity range is wide, usually 50-500 tons/hour, depending on the equipment model, material hardness, and feed particle size.
5. What maintenance does the mobile crushing station require?
• Regularly check the lubrication system (bearings, hydraulic oil).
• Clean the residual material in the crushing chamber to prevent clogging.
• Pay attention to tire wear for tire-type crushers, and maintain the crawler chain links for crawler-type crushers.
