1. PAINPOINT DRIVEN OPENING

Are you managing a midtolarge scale aggregate operation and facing persistent bottlenecks that erode profitability? For plant managers and engineering contractors, a 250300 tph stone crushing plant is a critical production asset, yet common operational challenges directly impact your bottom line.

Inconsistent Throughput: Fluctuations in feed size or hardness can cause chokeups or underutilization, failing to consistently hit the 250300 tph target and delaying project timelines.
Excessive Downtime for Maintenance: Frequent liner changes, bearing failures, or conveyor issues lead to unplanned stoppages. Industry data indicates that each hour of downtime in this capacity range can cost thousands in lost production and labor.
High Operational Costs: Spiking energy consumption from inefficient crushing chambers and escalating wear part costs due to suboptimal material flow consume your operating margin.
Product Quality Variability: Inability to precisely control final product gradation leads to offspec material, resulting in waste, recrushing, or rejected loads.

Is your current solution robust enough to handle abrasive granite or basalt at rated capacity? Can your plant’s design minimize points of failure? It’s time to evaluate a system engineered for reliable, costperton efficiency.

2. PRODUCT OVERVIEW

This brochure details a stationary ROHS Compliant 250300 TPH Stone Crushing Plant, a complete turnkey solution designed for highvolume production of aggregates for construction, road base, and railway ballast. The plant is configured for primary, secondary, and tertiary crushing stages to produce precisely graded final products.

Operational Workflow:
1. Primary Reduction: Large feed (≤750mm) is introduced to a robust jaw crusher or primary impactor for initial size reduction.
2. Secondary Crushing & Screening: Crushed material is conveyed to a cone crusher for further reduction. A vibrating screen separates material to route oversized particles back for recrushing (closedcircuit) and allows correctly sized material to proceed.
3. Tertiary Shaping & Final Sizing: For cubical product requirements, material may be sent to a tertiary vertical shaft impactor (VSI). Final screening decks separate output into multiple specified aggregate fractions (e.g., 05mm, 510mm, 1020mm).

Application Scope & Limitations:
Scope: Ideal for hard rock (granite, basalt), limestone, and river gravel processing. Suited for permanent quarry sites or longterm infrastructure projects requiring consistent, highvolume output.
Limitations: Not designed as mobile or skidmounted equipment. Feed size and abrasiveness must align with engineered crusher chamber specifications. Maximum capacity is contingent on specific material characteristics.
