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 250300 TPH stone crushing plant is a critical capital investment, yet standard configurations often fail to address core operational challenges.

Inconsistent Throughput & Downtime: Unplanned stoppages due to feeder blockages, crusher overloads, or conveyor misalignment can cost thousands per hour in lost production and idle labor.
High Operational & Maintenance Costs: Frequent wear part replacement, high energy consumption per ton processed, and the need for specialized maintenance crews directly impact your bottom line.
Poor Final Product Shape & Gradation: Inconsistent cubicity and excessive fines generation limit marketability for highvalue applications like concrete and asphalt, reducing revenue potential.
Site Layout & Logistics Inefficiency: Poorly designed material flow creates congestion, increases rehandling, and complicates future plant expansion.

Is your current setup delivering a reliable 300 tons per hour with predictable operating costs? Can you adapt your product mix quickly to meet changing market demands without major reconfiguration? The solution lies not just in individual machines, but in a fully integrated and optimized 250300tph stone crushing plant.

2. PRODUCT OVERVIEW

This solution is a complete, stationary crushing and screening plant engineered for continuous, highvolume production of aggregates from mediumhard to hard rock, such as granite, basalt, and limestone. It is designed as a threestage crushing system for optimal size reduction and product control.

Operational Workflow:
1. Primary Crushing: Dump trucks feed material into a robust vibrating grizzly feeder which bypasses sub100mm fines directly to a primary conveyor. Oversize material is crushed by a heavyduty jaw crusher.
2. Secondary & Tertiary Crushing: Primary crushed material is conveyed to a cone crusher for secondary reduction. For precise product shaping and finer specifications, material can be further processed by an additional cone crusher or impact crusher in a closed circuit with screens.
3. Screening & Stockpiling: Multiple deck vibrating screens classify material into specified final products (e.g., 05mm, 510mm, 1020mm). Oversize material is recirculated, while onspec aggregates are conveyed to designated stockpiles.

Application Scope: Ideal for large quarry operations, major infrastructure project support (highways, railways), and commercial aggregate suppliers requiring consistent, highvolume output.

Limitations: Not suitable for processing very abrasive or sticky materials (e.g., certain metal ores, clayheavy rock) without specific modifications to liner materials and handling systems.
