I. Key Selection Criteria: Precise Demand Matching to Avoid Resource Waste
Scenario Adaptation as the Top Priority
Hard Rock Crushing in Mines
Prioritize a combination of crawler-mounted jaw crushers and cone crushers. The crawler chassis features a low ground pressure, enabling it to climb slopes of up to 30 degrees and adapt to complex terrains such as mountainous regions and muddy ground.
Construction Waste Disposal
Select a wheel-mounted mobile crushing plant equipped with an iron separator. It allows for on-road transportation without disassembly, making it ideal for space-constrained scenarios like urban demolition projects.
Emergency Rescue & Disaster Relief
Prioritize lightweight models that support immediate operation upon arrival. With hydraulic support for rapid deployment, no complex site preparation is required.
Core Parameter Control
Processing CapacitySelect according to production requirements. A 20% capacity redundancy shall be reserved for hard rock crushing to prevent overload.
Crusher TypeChoose jaw crushers for primary crushing, and cone crushers or impact crushers for secondary and tertiary crushing. The finished product is required to have a high proportion of cubical particles.
Material CompatibilityAvoid standard models when processing wet and sticky materials. Alternatively, install drying or desliming devices to prevent blockage of the crushing chamber.

II.Safe Operation: Adhere to Safety Boundaries and Avoid Production Risks
Pre-Startup Inspection
Tighten the bolts of all components, check the hydraulic oil/lubricating oil levels, and clear residual materials from the crushing chamber.
For cone crushers, start the oil pump motor 5–10 minutes in advance. Only start the main motor after confirming the lubrication system is functioning properly.
Verify the belt tension and screen integrity to prevent detachment and injury during operation.
Operational Safety Specifications
Prohibit feeding uncrushable materials (e.g., ironware) into the crushing chamber. Prioritize models equipped with hydraulic tramp iron release function, which enables automatic discharge to avoid machine jamming.
When the finished product particle size becomes coarser, adjust the discharge opening via wedges/gaskets. Never perform direct adjustments while the equipment is in operation.
For models equipped with a PLC intelligent control system, assign special personnel to conduct remote monitoring and keep track of operational parameters in real time.
Shutdown Procedure
Stop feeding materials first. Shut down the main motor only after all materials in the crushing chamber are completely discharged, and finally turn off the oil pump motor.
Before long-term shutdown, clean the equipment, replenish oil supplies, tighten bolts, and test the reset function.
III.Maintenance Costs: Scientific Operation & Maintenance to Extend Equipment Service Life
Wear Part Management
Core Wear Parts: Jaw plates, liner plates, and ore distributors. For hard rock applications, keep 1–2 spare sets in stock. The service life of ore distributors can be extended by over three times by welding reinforcing rings.
Replacement Cycle: Replace liner plates promptly when wear exceeds 1/3 of their thickness. Shut down the equipment for spindle replacement if the wear of cone crusher spindles exceeds 3 mm.
Key Daily Maintenance Tasks
Lubrication System: Adopt thin oil lubrication and replace filter elements regularly to prevent oil-water mixing failures.
Hydraulic System: Inspect oil pipe leakage and track tension to avoid travel malfunctions.
Cleaning & Maintenance: Clean the belt conveyor and screening system daily, and check the spring reset function weekly.
Cost Control Tips
Select models with highly universal wear parts to reduce spare part procurement costs.
Arrange operator participation in manufacturer-provided training programs; improved operator skills can reduce equipment failure rates by 20%–30%.
IV.Environmental Compliance: Align with Regulatory Requirements to Alleviate Emission Reduction Pressures
Dust Control
Equipped with standard spray dust suppression systems/pulse jet dust collectors. Seal the interfaces between the crushing chamber and conveyor belts to avoid unorganized emissions.
For urban operations, prioritize electric-powered models or diesel engines complying with China National IV Emission Standard.
Noise Mitigation
Pay attention to noise parameters (≤85dB) when selecting equipment. Install sound insulation enclosures or opt for low-noise designed models.
Reasonably plan operation hours to avoid sensitive time periods in residential areas.
Resource Recycling
For construction waste disposal, configure iron separators and multi-stage screening equipment to realize classified recycling of recycled aggregates (specifications such as 0-5mm, 5-10mm, etc.).
Select integrated crushing-screening-conveying units to reduce pollution and loss during material transfer.
V. After-Sales Service: Choose Reliable Support to Minimize Downtime Losses
Core Service Requirements
Response Speed: Require 24/7 remote diagnosis (round-the-clock technical support).
Spare Parts Supply: Delivery time for wear parts ≤ 72 hours.
Training Support: Manufacturers shall provide operation and maintenance training. Trained operators can improve production efficiency by 10%–20%.
Manufacturer Capability Assessment
Verify the warranty period-core components shall have a warranty of ≥ 1 year. Request regular on-site inspection services as part of the package.
Key Contract Terms
Clarify the scope of after-sales service, including installation and commissioning, troubleshooting and repair, and technical upgrades.
