1. PAINPOINT DRIVEN OPENING

Managing a 250300tph stone crushing plant presents distinct logistical and operational hurdles that directly impact your bottom line. Are you facing:
Inconsistent Feed & Bottlenecks: Unreliable material flow from primary to secondary/tertiary stages, causing crusher idle time or overload, reducing actual throughput below the designed 250300tph capacity.
Excessive Downtime for Maintenance: Poor component accessibility and nonmodular design leading to extended shutdowns for liner changes, belt repairs, or bearing service, costing thousands per hour in lost production.
High Operational & Energy Costs: Inefficient plant layout requiring multiple material transfer points and conveyors, inflating power consumption and increasing wear part inventory costs across the entire crushing circuit.
Complex Setup & Relocation: Multiday assembly/disassembly for plant moves between sites or phases of a project, incurring significant labor costs and delaying revenue generation.

If these challenges sound familiar, the solution lies not just in individual machinery, but in a holistically engineered system. How do you achieve consistent rated capacity while controlling logistical complexity and total cost of ownership?

2. PRODUCT OVERVIEW

The OEM 250300tph Stone Crushing Plant is a complete, preengineered stationary or semimobile crushing circuit designed for highvolume production of aggregates for construction, road base, and railway ballast.

Operational Workflow:
1. Primary Crushing: Dump trucks feed material (e.g., granite, basalt, limestone) into a robust primary jaw crusher for initial size reduction.
2. Intermediate Screening & Conveying: Crushed material is conveyed to a primary screen which separates sized product from oversize material requiring further reduction.
3. Secondary/Tertiary Crushing: Oversize material is routed via closedcircuit conveyors to a cone crusher(s) for precise shaping and final size reduction.
4. Final Screening & Stockpiling: The output from all crushers is screened into specified fractions (e.g., 05mm, 520mm, 2040mm) and conveyed to designated stockpiles.

Application Scope & Limitations:
Scope: Ideal for largescale quarry operations, major infrastructure projects (highways, railways), and commercial aggregate suppliers requiring consistent, hightonnage output.
Limitations: Not suitable for highly abrasive or sticky materials without specific configuration adjustments. Site requires adequate space for plant layout and stockpile management. A stable electrical supply is necessary for optimal operation.
