The Hammer Crusher is a widely used crushing machine in mining, construction, and aggregate industries. It is designed to crush materials with medium hardness and brittleness into smaller sizes in a single stage, offering high efficiency and low operational cost.

What is a Hammer Crusher?

A Hammer Crusher is a type of impact crusher that uses high-speed rotating hammers to crush materials. When materials enter the crushing chamber, they are impacted, sheared, and ground by the hammers until they reach the required size.

This equipment is ideal for processing materials such as:
limestone, coal, gypsum, salt, brick, tile, shale, and various ores.

Key Advantages of Hammer Crusher

1. High Crushing Efficiency
The machine can achieve one-time crushing with high reduction ratio, reducing the need for secondary crushing equipment.

2. Simple Structure & Easy Maintenance
Compact design with fewer wearing parts ensures convenient operation and low maintenance cost.

3. Adjustable Output Size
The discharge size can be controlled by adjusting the grate bar gap, meeting different production requirements.

4. Energy Saving & Cost-Effective
Low energy consumption combined with high output makes it a cost-efficient solution for crushing operations.

5. Strong Adaptability
Suitable for various materials in mining, cement, coal, metallurgy, and construction industries.

Working Principle

The motor drives the rotor to rotate at high speed inside the crushing chamber. Materials fed into the machine are impacted by the rotating hammers and thrown against the impact plates.

During the crushing process:

• Materials are repeatedly struck by hammers

• Impacted against breaker plates

• Crushed and ground into smaller particles

• Qualified materials pass through the grate bars

• Oversized materials remain for further crushing

Technical Features

• Capacity: 3–100 tons per hour (customizable)

• Feeding size: ≤ 350 mm

• Output size: ≤ 25 mm (adjustable)

• Power: 11–90 kW

• Rotor speed: High-speed rotation for efficient crushing

• Hammer material: High manganese steel or alloy steel

Applications

Hammer Crushers are widely used in:

• Mining and mineral processing plants

• Quarry and aggregate production

• Cement and building material industries

• Coal crushing plants

They are often used together with:

• Jaw crushers (primary crushing)

• Wet pan mills or ball mills (grinding stage)

• Vibrating screens (size classification)
