250–300 TPH Stone Crushing Plant: Producer Datasheet and Technical Overview

Introduction

A 250–300 TPH (tonnes per hour) stone crushing plant represents a mid-to-high capacity aggregate production solution widely deployed in quarrying, construction, mining, and infrastructure projects. This datasheet-style article provides a structured technical overview of the equipment configuration, process flow, performance parameters, and producer considerations associated with plants in this capacity range. The information presented reflects typical industry configurations and is intended for engineers, project planners, and procurement specialists evaluating crushing solutions.

1. Capacity Definition and Basis of Design

The nominal capacity of 250–300 TPH refers to the throughput of finished product under standardized conditions: bulk density of feed material approximately 1.6 t/m³, moisture content below 5%, and feed size consistent with the primary crusher’s acceptance limit. Actual output varies with rock hardness (compressive strength), abrasiveness, feed gradation, and product specification. Producers typically quote capacity based on medium-hard limestone; harder materials such as granite or basalt may reduce effective throughput by 10–25%.

2. Typical Process Configuration

A complete 250–300 TPH plant generally comprises three or four crushing stages, depending on the required product shape and size distribution:

• Primary Crushing: A jaw crusher (e.g., PE-750×1060 or C-series equivalent) or a primary impact crusher reduces run-of-mine rock (up to 600–800 mm) to approximately 150–200 mm.
• Secondary Crushing: A cone crusher (e.g., CS/CH series) or impact crusher (e.g., PF-1214) further reduces material to 40–80 mm. For hard rock, cone crushers are preferred for their wear resistance and cubical output.
• Tertiary/Quaternary Crushing: A short-head cone crusher or VSI (vertical shaft impactor) produces fine aggregates (0–5 mm, 5–10 mm, 10–20 mm) with improved particle shape.
• Screening: Multi-deck vibrating screens (e.g., 3YK2160 or 4YK2460) classify material into commercial fractions. Closed-circuit configurations return oversize to the tertiary crusher.

3. Key Equipment Specifications (Typical Datasheet)

Note: Specifications are indicative and vary by manufacturer. Producers should confirm exact ratings against site-specific conditions.

4. Performance Parameters

• Throughput: 250–300 TPH (finished product, cumulative across all fractions).
• Product Fractions: Typically 0–5 mm, 5–10 mm, 10–20 mm, 20–31.5 mm, with adjustable screening.
• Power Consumption: Total installed power approximately 450–650 kW, depending on configuration and automation level.
• Water Consumption: 20–50 m³/h for dust suppression (optional wet process).
• Noise Level: 85–95 dB(A) at 1 m from major equipment; enclosures can reduce to ≤85 dB(A).
• Dust Emission: Controlled via bag filters or water sprays to meet local environmental standards (e.g., <20 mg/m³).

5. Producer Considerations and Datasheet Variables

When evaluating producers, the following parameters should be documented and compared:

1. Manufacturer Experience: Track record in similar capacity ranges and material types.
2. Equipment Quality: Material of construction (e.g., Mn18Cr2 jaw plates, high-chrome blow bars), bearing brands, and motor efficiency class.
3. Automation: PLC-based control, remote monitoring, and automatic load adjustment.
4. Mobility: Stationary, semi-mobile, or fully mobile (track-mounted) configurations.
5. Lead Time and Spare Parts: Availability of wear parts and service support.
6. Compliance: CE, ISO 9001, and local safety/environmental certifications.

6. Site Layout and Infrastructure Requirements

A 250–300 TPH plant typically requires:

• Footprint: 1,500–3,000 m² for stationary configuration, excluding stockpiles.
• Foundation: Reinforced concrete for crushers and screens; dynamic load considerations.
• Power Supply: 380–480 V, 50/60 Hz, with a dedicated transformer (≥800 kVA).
• Access Roads: Capable of supporting 40-tonne trucks for feed delivery and product dispatch.
• Stockpile Capacity: 3–5 days of production, depending on market logistics.

7. Operational and Maintenance Data

• Availability: Target ≥90% with scheduled maintenance.
• Wear Part Life: Jaw plates 800–1,500 hours; cone liners 600–1,200 hours; screen media 300–800 hours (material-dependent).
• Maintenance Schedule: Daily inspection, weekly lubrication, monthly wear checks, annual overhaul.
• Manpower: 4–8 operators per shift, plus maintenance crew.

8. Economic and Environmental Aspects

Producers should consider capital expenditure (CAPEX), operating expenditure (OPEX), and environmental impact. A typical 250–300 TPH plant has a CAPEX range of USD 350,000–900,000 (depending on automation and mobility) and an OPEX of USD 0.8–1.5 per tonne, including energy, wear parts, and labor. Environmental measures include dust suppression, noise barriers, and water recycling.

9. Selection Guidelines for Producers

To ensure optimal performance, producers should:

• Conduct feed material testing (hardness, abrasiveness, moisture).
• Define final product specifications precisely.
• Evaluate closed-circuit versus open-circuit configurations.
• Consider future capacity expansion (modular design).
• Request performance guarantees from suppliers.

10. Conclusion

The 250–300 TPH stone crushing plant is a versatile, proven solution for aggregate producers requiring reliable mid-range output. A well-documented datasheet, combined with careful producer evaluation and site-specific engineering, ensures maximum return on investment. Stakeholders should prioritize equipment quality, automation, and after-sales support when selecting a supplier.
