1. PAINPOINT DRIVEN OPENING

Are unpredictable feed materials and fluctuating production targets creating bottlenecks in your aggregate or recycling operation? Managing an impact crusher fleet often involves balancing competing priorities: achieving consistent product gradation, controlling wear part costs, and minimizing unplanned downtime for maintenance. When your primary or secondary crushing stage underperforms, the entire downstream process—screening, conveying, sorting—suffers, directly impacting your bottom line.

Key challenges include:
Excessive Wear Part Consumption: Abrasive feed material can lead to premature hammer and liner failure, resulting in high recurring costs and frequent operational pauses.
Inconsistent Product Shape: Poorly configured or worn impact crushers produce excessive fines or irregular particle shapes, reducing the value of your final product and limiting its market applications.
Unscheduled Downtime: The cumulative time lost for reactive maintenance, part changes, and clearing blockages can reduce annual throughput by 1520%, a significant loss in potential revenue.
Rigid Configuration Limitations: Fixed equipment may struggle to adapt to changing feed materials (e.g., from demolition concrete to asphalt millings), forcing suboptimal processing or requiring a separate machine.

How do you secure a reliable primary or secondary crushing solution that delivers consistent product specs while providing the flexibility to adapt to varying materials and maintain control over longterm operating expenses? The answer lies in selecting the right impact crusher partner with a clear commercial framework.

2. PRODUCT OVERVIEW: IMPACT CRUSHERS DISTRIBUTOR MINIMUM ORDER

This document outlines the commercial terms and technical specifications for establishing a supply partnership for industrialgrade horizontal shaft impact (HSI) crushers. These machines are engineered for highvolume reduction of medium to low abrasivity materials such as limestone, recycled concrete, asphalt, and construction debris.

Operational Workflow:
1. Feed Intake: Material is loaded into a deep chamber via a vibrating grizzly feeder or direct conveyor.
2. Acceleration & Impact: Highspeed rotating hammers (blow bars) strike the incoming feed, propelling it against adjustable primary and secondary impact aprons (curtains).
3. Size Control: The repeated impacts cause the material to fracture along natural cleavage lines. The gap between the rotor and aprons determines the maximum product size.
4. Product Ejection: Crushed material exits through the bottom of the chamber onto a discharge conveyor for further processing.

Application Scope & Limitations:
Ideal For: Quarried aggregate, recycled construction & demolition (C&D) waste, asphalt paving removal, nonabrasive industrial minerals.
WellSuited For: Primary or secondary crushing roles where producing a cubical product shape is a priority.
Limitations: Not recommended for highly abrasive materials (e.g., granite, trap rock) as primary crushers due to accelerated wear rates. Moisture content above 5% can lead to chamber clogging without proper configuration.
