1. PAINPOINT DRIVEN OPENING

Are you managing a midtolarge scale aggregate operation and facing consistent bottlenecks in your primary crushing circuit? The 250300tph range is critical, yet often where inefficiencies become costly. Common challenges include:
Inconsistent Throughput: Fluctuating feed size and hardness can cause production to drop below 250tph, failing to meet plant design goals and delaying downstream processes.
Excessive Downtime: Frequent mechanical adjustments, liner changes, and unscheduled maintenance in harsh processing environments lead to significant lost revenue—every hour of downtime can cost thousands in unrealized production.
High Operational Costs: Rising energy consumption per ton, coupled with the short service life of wear parts under continuous 300tph loads, erodes profit margins.
Product Quality Variability: Inability to precisely control crusher settings and manage fines generation results in offspec aggregate, reducing product value and marketability.

Is your current plant configuration delivering reliable, costeffective tonnage? This analysis outlines how a purposeengineered 250300tph stone crushing plant processing plant is designed to address these exact operational and financial pressures.

2. PRODUCT OVERVIEW

The 250300tph stone crushing plant is a complete stationary processing system engineered for highvolume production of aggregates for construction, road base, and railway ballast. It represents a fullcircuit solution from primary feed to final product stockpiling.

Operational Workflow:
1. Primary Reduction: Large quarryrun rock (up to 750mm) is fed into a robust primary jaw crusher for initial size reduction.
2. Secondary & Tertiary Crushing: The output is conveyed to secondary cone crushers for further reduction, with optional tertiary impact crushers for precise shaping and fines control.
3. Sizing & Classification: Crushed material is screened via multideck vibrating screens; oversize is recirculated, while correctly sized fractions are sent to designated stockpile conveyors.
4. Material Handling & Stockpiling: A network of belt conveyors and radial stackers efficiently moves and segregates final products (e.g., 05mm, 520mm, 2040mm).

Application Scope & Limitations:
Scope: Ideal for granite, basalt, limestone, and other mediumtohigh abrasiveness materials. Suited for large infrastructure projects requiring consistent, highvolume supply.
Limitations: Not designed for portable or mobile applications. Feed material hardness (above 350 MPa) may require specific metallurgy options. Site requires adequate space for equipment layout and stockpiles.
