The Top 5 Things You Need To Know About Mobile Crusher

Mobile crusher has revolutionized the crushing industry due to their flexible nature and ability to be transported from one work site to another. This has made them increasingly popular compared to stationary crushers which require setting up fixed crushing operations. As a buyer or user of mobile crusher, there are several crucial considerations to keep in mind for effective deployment and achieving optimal performance. Here are the top five things you need to know about mobile crusher.

1. Types of Mobile Crusher Available

There are different models of mobile crushers suited for various production needs. Knowing their individual characteristics helps selection for specific crushing tasks:

1. Mobile Jaw Crusher: Ideal for primary crushing of medium-hard materials. Heavy-duty jaw plates provide high output while small footprint suits transportation. Sizes range from 700x350mm to 1200x250mm.
2. Mobile Cone Crusher: Designed for secondary and tertiary hard rock crushing in small to large sizing applications. Advanced crushers offer hydraulic adjustment for maintaining size controls. Models feature opening sizes of 200-680mm.
3. Mobile Impact Crusher: Efficient for soft to medium-hard materials and low moisture applications. Suitable for both primary and secondary crushing. Models incorporate Vertical Shaft Impact (VSI) or Horizontal Shaft Impact (HSI) configurations.
4. Mobile VSI Crusher: Specialized for producing uniformly graded cubical aggregate or manufactured sand. Superior to jaw or cone models for artificial sand making. Capable of max feed size 50mm at outputs up to 300TPH.
5. Screening Units: Ancillary screens offered by major manufacturers enhance mobile crushing by separating sizing through multi-deck screening.

Choosing the right type based on material, capacity needs and product specifications ensures smooth operations and performance.

2. Key Specifications and Component Considerations

Key specifications and components determine a mobile crusher's construction ability. Proper sizing avoids operating restrictions while also ensuring safety and durability needs:

1. Feed Opening Size: Determines max input material size. Must match quarry/source sizes for optimal feeding.
2. Production Capacity: Ranges 30-500TPH depending on model. Match with application volumes to avoid unnecessary upsizing or downtime.
3. Engine Power: Diesel engines from 110-400kW provide process power. Verify power matches duty cycle demands.
4. Undercarriage: Tracked or wheeled, extends operational reach. Tracks preferred for soft terrain; wheels for roads. Check ground clearance and weight capacity.
5. Machine Weights: Affect transportation. Weights range 10-50 tons. Check moving/freight infrastructure capacities.
6. Electronics/Hydraulics: Automated controls offer safer, consistent crushing. Standard options available.
7. Serviceability: Maintenance access to components reduces downtime. Consider service platform designs for ease.

Detailed specifications and OEM expertise ensure optimal specifications for project conditions.

3. Mobility and Transportation Aspects

Flexibility is a key advantage of mobile crushing. Transport requirements affect mobilization feasibility that must be thoroughly assessed:

1. Self-propelled Modules: Each machine is a standalone unit for driving between sites under its own power.
2. Spread Axles: Wide axle spacing increases stability for road transport at reduced speeds up to 90kph.
3. Total Dimensions/Weight: Respecting length/width/height ensures compliance with standard truck configurations. Overweight requires special permits.
4. Restraint Devices: Proper chains, straps and tensioners secure equipment for safe transport over long distances.

Thorough planning ensures compliance. Potential delays/costs from improper specifications can outweigh savings from mobile flexibility.

4. Crushing Process and Operation

Efficient crushing demands fully understanding process flow to optimize uptime:

1. Material Feeding: Hoppers provide even flow to primary crushers. Grizzly bars screen out oversized rock for separate processing.
2. Crushing Chambers: Jaw, cone or impact crushers reduce sizes in sequential stages. CSS control ensures product consistency.
3. Vibration Screening: Multi-layer screen decks separate sizing. Top deck overs recirculate to secondary crushing as needed.
4. Conveying: Renowned belt, chain or pan feeder styles transport material between processes without breaking bulk.
5. Stockpile Management: Forming layered piles prevents segregation. Front-end loaders accurately reclaim to customer specifications.
6. Process Control: PLC units with touchscreens monitor operations and alert on maintenance needs. Automation conserves labor costs.

Understanding flow aids troubleshooting, adjusting parameters, and boosting utilization.

5. Mobile Crusher Maintenance

Regular upkeep maintains performance and availability through scheduled component replacements:

1. Wear Parts: Jaw dies, blow bars and screens require monitoring for timely swapping out to avoid unplanned downtime. OEM spares ensure quality.
2. Lubrication: Daily greasing of hoses, bearings and slide surfaces prevents excess wear. All-in-one lubrication units simplify maintenance.
3. Cooling Systems: Radiators, oil coolers and hydraulic tanks keep components functioning at optimal temperatures. Periodic cleaning removes accumulation.
4. Electricals: Generator sets demand routine servicing for reliable operation. Back-up power prevents downtime during engine reconditioning.
5. Safety Equipment: Fire extinguishers, fall protection and first aid kits fulfill compliance. Regular inspections ensure readiness.
6. Washdowns: Washing components after working removes build-up of debris and scale to safeguard components.

Documented preventive maintenance schedules, spare parts management and trained technicians sustain equipment longevity between projects.

Understanding these five vital aspects of mobile crusher - types, specifications, mobility, process operation and maintenance - equips buyers and site engineers with knowledge for successful deployment and optimal utilization of these flexible crushing systems. Proper planning and execution delivers productivity and return on investment from mobile crushing equipment.
