What is the HP300 Tertiary C One Crusher?

The HP300 is a high-performance cone crusher manufactured by Metso (now Metso Outotec), part of the renowned HP (High Performance) series. The “Tertiary C One” designation refers to its optimized configuration for tertiary crushing duties—where the goal is to reduce material from 50–80 mm down to 0–20 mm or finer—while the “C” typically indicates a coarse crushing chamber variant, and “One” denotes a single-unit, standalone crushing solution.

Unlike primary or secondary crushers, the HP300 tertiary cone crusher is engineered for fine crushing, high reduction ratios, and superior product shape. It is widely used in hard rock applications, including granite, basalt, quartzite, and iron ore, as well as in recycled concrete and asphalt processing.

Key Technical Specifications

To fully appreciate the HP300’s capabilities, it is essential to examine its core specifications:

• Crusher Weight: Approximately 15,810 kg (34,850 lbs) for the main frame assembly
• Motor Power: 220 kW (300 HP)
• Closed Side Setting (CSS) Range: 6–32 mm (0.24–1.26 in)
• Capacity Range: 120–250 metric tons per hour (depending on feed size and CSS)
• Max Feed Size: Up to 230 mm (9 in) for the coarse chamber
• Eccentric Throw: Adjustable from 16 mm to 30 mm
• Chamber Options: Coarse (C), Medium (M), Fine (F), and Extra Fine (EF)

These specifications make the HP300 a versatile machine that can be adapted to a wide range of production requirements, from high-tonnage aggregate plants to specialized mineral processing operations.

How Does the HP300 Tertiary Crusher Work?

The working principle of the HP300 is based on the multi-cylinder hydraulic cone crusher concept. The main components include:

1. Main Shaft and Eccentric Assembly: The eccentric sleeve rotates around the main shaft, causing the mantle to oscillate.
2. Mantle and Concave: The mantle (moving part) and concave (fixed part) form the crushing chamber. As the mantle gyrates, the gap between the mantle and concave opens and closes, compressing the material.
3. Hydraulic Adjustment System: The CSS can be adjusted hydraulically, allowing operators to change the product size without manual intervention.
4. Tramp Release System: If uncrushable material (e.g., steel bars) enters the chamber, the hydraulic system automatically opens the crusher to let the material pass, then resets to the original setting.

In tertiary applications, the HP300 operates at a higher speed and finer stroke compared to primary crushers, which enhances inter-particle breakage. This results in a cubical product shape, reduced flakiness, and a higher percentage of fines—ideal for asphalt and concrete aggregates.

Why Choose the HP300 for Tertiary Crushing?

1. Unmatched Reduction Ratio

The HP300 can achieve reduction ratios of up to 6:1 in tertiary applications. This means fewer crushing stages are required, reducing capital expenditure and operational complexity.

2. Superior Product Quality

Thanks to its advanced chamber design and high eccentric throw, the HP300 produces a well-graded, cubical product with minimal flat or elongated particles. This is critical for meeting strict specifications in road construction and concrete production.

3. Energy Efficiency

The HP300 is designed to deliver maximum power efficiency. Its optimized crushing cavity and hydraulic drive system reduce energy consumption per ton of product, lowering overall operating costs.

4. Automation and Remote Monitoring

The HP300 is compatible with Metso’s IC70C automation system, which continuously monitors crusher load, power draw, and oil temperature. This allows for real-time adjustments, predictive maintenance, and integration into plant-wide control systems.

5. Robust and Durable Construction

Built with high-grade cast steel and forged components, the HP300 is designed for 24/7 operation in demanding environments. Its wear parts are engineered for extended service life, reducing downtime and replacement frequency.

Application Scenarios

The HP300 Tertiary C One Crusher is suitable for a variety of industries and materials:

• Aggregate Production: Producing high-quality crushed stone for concrete, asphalt, and railway ballast.
• Mining Operations: Fine crushing of ore before grinding, especially in gold, copper, and iron ore processing plants.
• Recycling Industry: Processing reinforced concrete and asphalt waste into reusable aggregates.
• Industrial Minerals: Crushing limestone, dolomite, and gypsum for cement and chemical industries.

Comparison with Other Crushers

To understand the HP300’s position in the market, it is useful to compare it with other common tertiary crushers:

Feature	HP300 Cone Crusher	VSI (Vertical Shaft Impactor)	HSI (Horizontal Shaft Impactor)
Reduction Ratio	High (up to 6:1)	Very High (up to 10:1)	Medium (up to 4:1)
Product Shape	Excellent (cubical)	Excellent (cubical)	Good (some flakiness)
Wear Cost	Moderate	High (due to high speed)	Low to Moderate
Feed Moisture Tolerance	Good	Limited	Good
Hard Rock Suitability	Excellent	Good	Limited

While VSI crushers offer higher reduction ratios, they suffer from higher wear costs and are less effective on very hard, abrasive materials. The HP300 strikes the optimal balance between performance, cost, and durability.

Installation and Integration Tips

For optimal performance, the HP300 should be installed with the following considerations:

• Feed Distribution: Use a properly designed feed hopper and chute to ensure a uniform, well-distributed feed across the crushing chamber. Segregated or uneven feed can lead to uneven wear and reduced capacity.
• Surge Capacity: Install a surge bin or vibrating feeder ahead of the crusher to maintain a constant, choke-fed condition. Choke feeding maximizes crushing efficiency and product quality.
• Screening: In tertiary circuits, a closed-circuit configuration with a screen is recommended to return oversized material back to the crusher, ensuring a consistent final product.
• Foundation and Vibration Isolation: The crusher should be mounted on a reinforced concrete foundation with vibration dampers to minimize structural stress and noise.

Maintenance and Operational Best Practices

To maximize the lifespan and performance of your HP300, adhere to the following maintenance guidelines:

Daily Checks

• Inspect oil level and oil condition in the lubrication system.
• Monitor hydraulic pressure and temperature.
• Check for abnormal noise or vibration.
• Verify that the CSS is within the specified range.

Weekly Checks

• Inspect wear parts (mantle and concave) for signs of excessive wear or cracking.
• Check the condition of the V-belts and drive assembly.
• Clean the cooling system and air filters.

Monthly Checks

• Test the tramp release system with a simulated uncrushable object.
• Inspect the main shaft bushing and eccentric bushing for wear.
• Grease all lubrication points as per the manufacturer’s manual.

Predictive Maintenance

• Use the IC70C automation system to track trends in power draw, oil temperature, and CSS. Sudden changes can indicate developing issues, allowing for proactive intervention.
