Zenith HP300 Cone Crusher: Specifications, Applications, and Buying Guide

The Zenith HP300 cone crusher is a high-performance crushing machine designed for secondary, tertiary, and quaternary crushing stages in mining, quarrying, and aggregate production. Built on the proven HP (High Performance) series platform, the HP300 combines high crushing force, optimized cavity design, and hydraulic adjustment to deliver consistent output, excellent product shape, and low operating costs.

This guide covers everything you need to know about the Zenith HP300 — including its specifications, working principle, applications, advantages, and how to choose the right configuration for your project.

What Is the Zenith HP300 Cone Crusher?

The Zenith HP300 is a medium-to-large capacity cone crusher featuring a 1,120 mm (approximately 44 inches) head diameter. It is engineered to handle hard and medium-hard materials such as granite, basalt, river stone, iron ore, copper ore, limestone, and quartz.

Unlike traditional spring cone crushers, the HP300 uses a hydraulic clearing and adjustment system, allowing operators to change the closed side setting (CSS) quickly and clear tramp material safely. This makes it ideal for modern, high-throughput crushing plants where uptime and product consistency matter.

Key Specifications of the Zenith HP300 Cone Crusher

Note: Actual capacity depends on feed material, cavity type, CSS, moisture content, and circuit configuration.

How the HP300 Cone Crusher Works

The HP300 operates on the principle of laminar crushing — material is compressed between a moving mantle and a fixed concave bowl liner. Key components include:

1. Eccentric assembly – rotates to create the gyrating motion of the main shaft.
2. Mantle and bowl liner – the wear parts that directly crush material.
3. Hydraulic cylinder – provides overload protection, CSS adjustment, and cavity clearing.
4. Drive system – transfers power from the motor through the countershaft to the eccentric.
5. Control system – monitors load, power draw, and discharge setting for stable operation.

Because the crushing chamber is designed to crush material against material (not just against steel), the HP300 produces a more cubical product with less flakiness — a major advantage for concrete aggregate and asphalt applications.

Main Advantages of the Zenith HP300

• High reduction ratio – reduces the number of crushing stages required.
• Excellent product shape – cubical particles with low needle-like content.
• Hydraulic CSS adjustment – fast, precise, and safe.
• Overload protection – tramp iron passes through without damaging the machine.
• Wear-resistant liners – extended service life and lower cost per ton.
• Compact footprint – easy to integrate into mobile or stationary plants.
• Consistent gradation – stable output even as liners wear.

Common Applications

The Zenith HP300 is widely used in:

• Aggregate production – producing 0–5 mm, 5–10 mm, 10–20 mm, and 20–40 mm fractions.
• Mining – secondary and tertiary crushing of copper, gold, iron, and zinc ores.
• Construction waste recycling – processing concrete and demolition debris.
• Sand manufacturing – combined with VSI crushers for manufactured sand lines.
• Cement industry – crushing limestone, clinker, and additives.

How to Choose the Right HP300 Configuration

When selecting an HP300 for your plant, consider:

1. Feed size and hardness – determines the cavity type (C, M, F, or EF).
2. Target product size – defines the required CSS range.
3. Throughput requirement – match capacity to your circuit balance.
4. Circuit type – open or closed circuit affects final gradation.
5. Power supply – ensure the motor and drive match local voltage and frequency.
6. Automation level – advanced control systems improve efficiency and safety.

For most secondary crushing duties, a medium or coarse cavity is recommended. For tertiary and quaternary duties, fine or extra-fine cavities deliver the best shape and gradation.

Maintenance Tips for Longer Service Life

• Inspect mantle and bowl liner wear regularly and rotate or replace on time.
• Maintain correct CSS to avoid excessive power draw.
• Keep the hydraulic system clean and check oil pressure.
• Lubricate the eccentric and drive components per the manual.
• Monitor vibration, temperature, and current to detect early faults.
• Use genuine Zenith spare parts to ensure fit and durability.

Frequently Asked Questions (FAQ)

Q1: What is the maximum feed size of the Zenith HP300?
A: It depends on the cavity. Coarse cavities accept up to about 240 mm, while fine cavities accept smaller feed.

Q2: What is the capacity of the HP300?
A: Typically 115–440 t/h, depending on CSS, cavity, and material characteristics.

Q3: Can the HP300 be used for primary crushing?
A: It is generally used for secondary, tertiary, or quaternary crushing. Primary crushing usually requires a jaw crusher or gyratory crusher.

Q4: Is the HP300 suitable for mobile crushing plants?
A: Yes. Its compact design and hydraulic adjustment make it ideal for track-mounted and wheel-mounted mobile units.

Q5: How long do the liners last?
A: Liner life varies with material abrasiveness and throughput, typically ranging from several hundred to over a thousand hours.

Conclusion
