1. PAINPOINT DRIVEN OPENING

Are you managing a highvolume aggregate operation where inconsistent feed material and unplanned downtime are eroding your profit margins? For plant managers and engineering contractors, a 250300 tph stone crushing plant is a critical production asset, yet common operational challenges persist:
Variable Feedstock Costs: Fluctuations in rock hardness and size degrade throughput, causing you to miss daily tonnage targets and increasing wear part consumption unpredictably.
Unscheduled Downtime: Component failures in key crushers or screens halt the entire line, costing thousands per hour in lost production and idle labor.
Inefficient Material Flow: Bottlenecks between crushing stages or inadequate screening lead to recirculating loads, wasting energy and accelerating equipment wear.
Quality Control Inconsistency: Inability to precisely control final product gradation results in outofspec material, leading to rejected loads and contract penalties.

How do you secure a reliable flow of onspec aggregate while controlling operational costs and maximizing equipment uptime? The solution lies in a purposeengineered, ISOcertified 250300tph stone crushing plant designed for predictable performance.

2. PRODUCT OVERVIEW

This solution is a stationary or semistationary primarysecondarytertiary stone crushing plant engineered for consistent output of 250 to 300 metric tons per hour of crushed aggregate. It is manufactured under a private label arrangement by an ISO 9001:2015 certified heavy machinery facility, ensuring documented quality control from design to assembly.

Operational Workflow:
1. Primary Reduction: Dumpfed material is crushed by a robust primary jaw crusher or gyratory crusher to a manageable size for downstream processing.
2. Secondary Crushing & Primary Screening: Material is conveyed to a secondary cone crusher for further reduction. A primary screen separates sized product from material requiring additional crushing.
3. Tertiary/Quaternary Shaping: Oversize material is routed to tertiary cone crushers or impactors for precise shaping and final size reduction.
4. Final Screening & Stockpiling: Crushed stone passes through final sizing screens where it is sorted into specified product grades (e.g., base course, chips, dust) and conveyed to designated stockpiles.

Application Scope & Limitations:
Scope: Ideal for largescale quarry operations, major infrastructure projects (road/highway construction), commercial concrete/asphalt plants requiring consistent feed, and dedicated aggregate supply yards.
Limitations: Not suitable for highly mobile applications requiring frequent relocation. Feed rock hardness must be within the designed compressive strength parameters of the selected crusher liners. Requires substantial initial capital investment and prepared site foundation.
