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 asset, yet standard configurations often introduce hidden costs. Common challenges include:
Unscheduled Downtime: Component failures in feeders, crushers, or conveyors can halt your entire line, costing thousands per hour in lost production and idle labor.
Inconsistent Final Product: Fluctuations in feed size or hardness lead to offspec aggregate, reducing premium product yield and forcing recrushing.
High Operational Costs: Inefficient power draw from poorly matched motors and excessive wear part consumption directly impact your costperton metric.
Scalability Limitations: Fixed plant designs struggle to adapt to new material sources or changing market demands for different aggregate sizes.

Is your current setup delivering the predictable throughput and consistent product gradation required for profitable contracts? The solution lies not just in machinery, but in a holistically engineered 250300tph stone crushing plant designed for operational certainty.

2. PRODUCT OVERVIEW

This product is a complete, stationary 250300 ton per hour (TPH) hard rock crushing and screening plant, supplied as a turnkey system or modular units for fast deployment. It is engineered for processing granite, basalt, limestone, and other abrasive aggregates to produce precisely graded crushed stone.

Operational Workflow:
1. Primary Reduction: Dumpfed material is consistently delivered to a robust primary jaw crusher for initial size reduction.
2. Secondary & Tertiary Crushing: The output is conveyed to secondary (cone) and tertiary (cone or impact) crushers in closed circuit with screens for controlled particle shaping and further reduction.
3. Sizing & Sorting: Multipledeck vibrating screens accurately separate crushed material into specified final product sizes (e.g., 05mm, 510mm, 1020mm).
4. Stockpiling: Onboard conveyor systems transfer sorted aggregates to designated stockpiles.
5. Dust Suppression: Integrated spray systems at transfer points control particulate emissions.

Application Scope & Limitations:
Scope: Ideal for dedicated aggregate quarries, large infrastructure project sites (road/highway construction), and commercial concrete/asphalt plants requiring highvolume, consistent feed.
Limitations: Not suitable for smallscale (<150TPH) operations due to capital outlay. Requires stable foundation preparation and threephase highvoltage power supply. Maximum feed size is determined by the primary crusher model selected.
