1. PAINPOINT DRIVEN OPENING

Are you managing a midtolarge scale aggregate production operation and facing persistent bottlenecks that erode profitability? For plant managers and engineering contractors, a 250300tph stone crushing plant is a critical capital asset, yet common operational challenges can significantly undermine its return on investment.

Inconsistent Throughput: Fluctuations in feed material hardness or size can cause chokeups or underutilization, failing to consistently hit the 250300 ton per hour target and delaying project timelines.
High Operational Downtime: Frequent maintenance stops for wear part replacement or unplanned mechanical failures directly translate to lost revenue, often exceeding thousands of dollars per hour in idle capacity.
Excessive Energy Consumption: Inefficient crushing chambers and poorly matched componentry can lead to disproportionately high power costs per ton of finished aggregate.
Product Quality Variability: Inability to precisely control final product cubicity and gradation leads to offspec material, reducing its market value or causing rejections.
Rapid Wear Part Degradation: The wrong configuration for your primary rock type accelerates wear in crushers, screens, and conveyors, creating unpredictable cost spikes and inventory headaches.

Is your current setup delivering predictable throughput with controlled operational expenses? Can you reliably meet stringent aggregate specifications while maintaining a low costperton metric? The following solution addresses these exact engineering and commercial challenges.

2. PRODUCT OVERVIEW

This 250300tph stationary stone crushing plant is a complete, hardrock processing circuit engineered for continuous, highvolume production of aggregates for construction, road base, and railway ballast. It is designed as a multistage crushing and screening system for processing mediumhard to hard stones such as granite, basalt, river pebbles, and limestone.

Operational Workflow:
1. Primary Crushing: Large feed material (≤750mm) is reduced by a robust primary jaw crusher or gyratory crusher.
2. Secondary & Tertiary Crushing: The output is conveyed to secondary (cone crusher) and optionally tertiary (cone or impact crusher) stages for further size reduction and shape refinement.
3. Screening & Classification: Material is routed through vibrating screens to separate it into precise product fractions (e.g., 05mm, 510mm, 1020mm).
4. Material Handling & Stockpiling: Closedcircuit conveyors recirculate oversize material back to the appropriate crusher, while onspec product is conveyed to designated stockpiles.

Application Scope & Limitations:
Scope: Ideal for large quarry operations, major infrastructure projects requiring dedicated onsite supply, and commercial aggregate suppliers serving regional markets.
Limitations: This is a stationary plant configuration requiring foundational work and substantial electrical supply. It is not suitable for frequent relocation. Extremely abrasive or sticky materials may require specific liner configurations and more intensive maintenance protocols.
