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 represents a critical production tier, yet common operational challenges can significantly undercut its potential. These include inconsistent feed size causing crusher chokeups, leading to 1520% unexpected downtime. Premature wear on liners and crusher parts due to suboptimal chamber design or material flow, increasing consumable costs by up to 30%. Inefficient screening resulting in product recirculation loads exceeding 25%, wasting energy and capacity. Difficulty in maintaining a consistent product gradation across multiple specs, leading to rejected loads and customer disputes. And finally, the high operational cost of supporting equipment with frequent breakdowns and complex maintenance routines.

Is your current setup delivering the reliable, costperton output required for competitive bidding and sustained margins? The solution lies not just in individual machines, but in a holistically engineered 250300tph stone crushing plant designed from the ground up to address these exact pain points.

2. PRODUCT OVERVIEW

This solution is a stationary, hardrock stone crushing and screening plant engineered for a nominal output of 250 to 300 metric tons per hour (TPH) of finished aggregate. It is designed for primary contractors and quarry owners requiring highvolume, consistent production of base materials, concrete aggregates, and road stone.

Operational Workflow:
1. Primary Crushing & Scalping: Large feed (≤750mm) is reduced by a primary jaw crusher. A heavyduty vibrating grizzly feeder removes fines prior to crushing to enhance efficiency.
2. Secondary Crushing & Shaping: The primary crushed material is conveyed to a secondary cone crusher for further size reduction and improved particle shape.
3. Tertiary/Fine Crushing (Optional): For producing specific chip sizes or sand, a tertiary cone crusher or vertical shaft impactor (VSI) can be integrated.
4. Material Screening & Classification: Multipledeck vibrating screens sort the crushed material into precise product fractions (e.g., 05mm, 510mm, 1020mm).
5. Stockpiling & Conveying: Radial stackers or fixed conveyors transfer sorted aggregates to designated stockpiles.

Application Scope & Limitations:
Scope: Ideal for granite, basalt, limestone, and other abrasive aggregates. Suited for large infrastructure projects, commercial quarrying, and dedicated aggregate supply yards.
Limitations: Not designed for portable or mobile applications requiring frequent relocation. Feed material compressive strength should not exceed design specifications (typically up to 350 MPa). Requires stable foundation preparation and gridbased power connection.
