1. PAINPOINT DRIVEN OPENING

Are you managing a midtolarge scale aggregate production operation and facing persistent bottlenecks that erode profitability? The challenges of a 250300 tph stone crushing plant are often clear: inconsistent feed material causing crusher stalls and wear, excessive downtime for liner changes and maintenance, high energy consumption per ton of output, and difficulty meeting strict aggregate specifications consistently. These issues translate directly to lost revenue. How much production are you losing during changeovers? What is the true cost of unplanned downtime on your project timelines? Are your operational costs under control, or are they being inflated by inefficient processes and premature component failure? A wellengineered, customized OEM 250300tph stone crushing plant is designed to systematically address these exact pain points.

2. PRODUCT OVERVIEW

This solution is a complete, heavyduty stationary or semistationary stone crushing plant engineered for reliable production of 250 to 300 metric tons per hour of crushed aggregate. It is not an offtheshelf product but a configured system built around core OEM crushers, screens, and conveyors.

Operational Workflow:
1. Primary Reduction: Large feed material (up to 750mm) is reduced by a robust primary jaw or gyratory crusher.
2. Secondary/Tertiary Crushing: Material is conveyed to secondary cone or impact crushers for further size reduction and shaping.
3. Sizing & Classification: Crushed material passes through multideck vibrating screens to separate it into precise product fractions (e.g., 05mm, 510mm, 1020mm).
4. Stockpiling & Recirculation: Onspec material is conveyed to stockpiles. Oversize material is automatically recirculated back into the circuit for recrushing.

Application Scope: Ideal for large quarry operations, major infrastructure projects (highways, railways), and commercial concrete/asphalt plants requiring highvolume, consistent aggregate supply.
Limitations: Requires significant capital investment and planned site preparation. Optimal performance depends on correct system configuration for the specific feed material characteristics (abrasiveness, silica content, moisture).
