Mobile concrete crusher is an efficient and flexible equipment, which is specially used for on-site crushing and recycling of construction waste (such as waste concrete).
Mobile jaw crusher is the core model of concrete crushing equipment, especially suitable for primary crushing (coarse crushing) of large concrete.
1. Core advantages of the mobile jaw crusher
• Powerful coarse crushing: The jaw plate design can crush high-hardness concrete (compressive strength ≤350MPa) and handle large materials (feed size is usually ≤500mm).
• Convenient to move: crawler or tire chassis, suitable for demolition sites and urban construction waste on-site operations, without fixed foundation.
• Integrated design: Integrates feeding, crushing, screening and conveying, reducing the number of equipment and reducing operating costs.
2. Recommended type:
Jaw mobile crusher (coarse crushing) + impact or cone mobile crusher (medium and fine crushing), the combination can meet the efficient processing of concrete crushing.
3. Key parameter matching
Feed size: Concrete blocks are usually ≤500mm and need to be pre-processed (such as hydraulic hammer crushing) to fit the feed port.
Discharge particle size: Adjust according to demand (such as 0-30mm recycled aggregate), and can be graded by screening equipment (such as vibrating screen).
Power configuration: Diesel generator or external power supply, the power needs to match the host (such as 200-300kW).
4. Key parameters of 60-100tph model
| Projects | Parameter range | Remarks |
| Processing capacity | 60-100tph (actually affected by concrete hardness and humidity) | 10%-15% capacity redundancy needs to be reserved |
| Feed size | ≤500mm (pre-processing to ≤300mm is recommended) | Too large pieces can easily cause material jamming or equipment wear |
| Discharge size | 50-150mm (adjustable) | Can be connected to impact crusher or screening machine for refinement |
| Power system | Diesel/motor drive, power 90-160kW | Diesel engine is suitable for sites without electricity (such as XCMG XE150) |
| Equipment weight | 30-50 tons (crawler type is more stable, tire type moves faster) | Road weight limit needs to be considered for transfer |
5. Precautions for concrete crushing
• Steel bar processing: It is recommended to configure an iron remover or manual pre-sorting to prevent steel bars from wrapping around the rotor.
Some models (such as the Sanmei JC series) can be equipped with optional hydraulic overload protection to prevent jamming.
• Wear control: Use high manganese steel jaw plates and check wear regularly (lifespan is about 500-1000 hours).
Wet concrete needs to strengthen vibration feeding to prevent sticking.
6. Supporting solution optimization
• Single machine operation: The jaw crusher station can be used independently if only coarse aggregate is required (such as roadbed filling).
• Combined operation: The combined impact crusher can further refine the output to the recycled aggregate standard (such as 0-5mm, 5-10mm).
7. Cost estimation
• Equipment procurement: Domestic models are about 800,000-1.2 million yuan, and imported models are 1.5-2.5 million yuan.
• Operating costs: Diesel fuel consumption is about 15- 25L/hour, and the annual cost of replacing wearing parts is about 30,000-50,000 yuan.
FAQ
1. Can this mobile jaw crusher process concrete with steel bars?
• It is recommended to configure an iron remover (about +20,000 yuan) to automatically separate the steel bars;
• Large steel bars (>30cm) need to be pre-sorted manually to avoid the jaw plate from getting stuck.
2. Is the 60-100 ton capacity the maximum or stable value?
• Concrete hardness (more efficient below C30);
• Feed uniformity (it is recommended to use a vibrating feeder);
• The stable value is recommended to be calculated as 80% of the nominal value (e.g. 100tph model is planned as 80tph).
3. Can the crushed concrete aggregate be directly used for recycled building materials?
• Coarsely crushed aggregate (50-150mm) → requires secondary crushing (impact crusher) to 0-30mm;
• When the mud content is high, water washing and screening is required (additional equipment).
