1. PAINPOINT DRIVEN OPENING

Are you managing a midtolarge scale aggregate operation and facing persistent bottlenecks in output and compliance? For plant managers and engineering contractors, a 250300 tph crushing plant is a critical production asset, yet standard configurations often introduce significant operational friction. Common challenges include:
Unplanned Downtime: Component failures in nonintegrated systems can halt your entire line for 2448 hours, costing thousands in lost production and labor.
Regulatory & Tender Disqualification: An increasing number of municipal and international construction projects now mandate RoHS (Restriction of Hazardous Substances) compliance for equipment. Noncompliant plants risk being excluded from lucrative contracts.
Inconsistent Throughput: Fluctuations in feed material or suboptimal crushing chamber flow lead to an average output below the 280 tph target, failing to meet project schedules.
High Lifetime Operating Costs: Frequent replacement of nondurable wear parts and energyinefficient drives silently erode profit margins over a 5year period.
Operational Complexity: Plants requiring constant manual adjustment and monitoring divert skilled personnel from highervalue maintenance and optimization tasks.

The central question is: how can you achieve reliable, highvolume production while futureproofing your investment against evolving environmental regulations? The solution lies in a purposeengineered RoHS Compliant 250300tph Stone Crushing Plant.

2. PRODUCT OVERVIEW

This product is a stationary or semistationary aggregate production plant engineered for consistent output within the 250 to 300 tonnesperhour range. It is designed from the ground up to comply with RoHS Directive 2011/65/EU, ensuring the controlled use of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE in its electrical components, coatings, and manufactured assemblies.

Operational Workflow:
1. Primary Crushing: Large feed material (≤750mm) is reduced by a robust jaw crusher or gyratory crusher.
2. Secondary & Tertiary Crushing: Material is conveyed to cone crushers for further size reduction and shaping to meet specific aggregate gradations.
3. Screening & Sorting: Vibrating screens separate crushed material into specified product sizes; oversize material is recirculated.
4. Material Handling: A network of conveyors with centralized control ensures efficient transfer between stages.
5. Dust Suppression: Integrated spray systems control particulate emissions at transfer points.

Application Scope: Ideal for producing aggregates for road base, readymix concrete, asphalt, and railway ballast. Suitable for granite, limestone, basalt, and river gravel.

Limitations: Not designed for abrasive metal ores or sticky, highclay content materials without specific feeder and crusher configuration modifications.
