Product Description
Impact crusher blow bars are widely used in aggregate shaping and recycling operations where stable crushing efficiency and superior wear resistance are required. Manufactured from Cr15, Cr20, and Cr26 high chrome iron materials, these blow bars deliver powerful impact crushing capability and excellent fracture toughness during continuous operation. Composite ceramic insert blow bars are available for highly abrasive conditions requiring longer operational lifetime. Their optimized rotor profile improves reduction ratios and aggregate particle shape while maintaining stable machine balance. Suitable for limestone, asphalt, and recycled concrete processing, these crusher wear parts help improve throughput and reduce maintenance downtime in industrial crushing plants.
Description of Mining Crushing Wear Parts
In crushing systems for mining, quarrying, aggregate making, recycling, and construction, crusher wear parts are critical consumable components. They directly determine crushing efficiency, output morphology, machine reliability, and total expense. HUATAO GROUP offers a full range of premium wear parts including jaw crusher jaw plates, impact crusher blow bars, and cone crusher mantle & concave. Crafted from high manganese steel, high chrome iron, alloy steel, and blends, our parts provide high abrasion resistance, impact toughness, and long service life under demanding working environments.
Crusher Type
Crushers are essential equipment in mineral processing plants, designed to reduce large rocks into smaller particles. Different types of crushers are used in various crushing stages, each with its own set of wear parts that require regular replacement. Below is an overview of common crusher types and their key consumable parts:

Product 1: Jaw Plate
1.1 Applicable Crusher Type: Jaw Crusher
1.2 Definition and Application:
The Jaw Plate is the primary wear component in a Jaw Crusher that comes into direct contact with materials. It consists of fixed and movable plates mounted on the jaw frame, used to crush hard materials such as rocks and ores through compressive force.
1.3 Advantages:
- High wear resistance, extending replacement cycles
- Optimized tooth profile design improves crushing efficiency
- Reduces equipment vibration and noise
- Lowers energy consumption and increases production output
1.4 Common Materials:
- High Manganese Steel (Mn13, Mn18Cr2)
- Medium Manganese Steel
- Alloy Steel
- Composite Materials (e.g., high-chrome iron inserts)

Product 2: Mantle & Concave
2.1 Applicable Crusher Type: Cone Crusher
2.2 Definition and Application:
The Mantle and Concave are the core wear components of a Cone Crusher. The Mantle is mounted on the top of the main shaft and performs an eccentric gyrating motion. Together with the fixed Concave, they form the crushing chamber to achieve multi-layer compressive crushing of materials.
2.3 Advantages:
- Precision casting ensures stable crushing chamber shape
- Even wear distribution extends service life
- Improves particle shape quality, reducing needle/flake particles
- Suitable for medium to high hardness materials in secondary/tertiary crushing
2.4 Common Materials:
- High Manganese Steel (Mn18Cr2, Mn22Cr2)
- Ultra-High Manganese Steel
- Alloy Steel (containing Mo, Ni, etc.)

Product 3: Blow Bar
3.1 Applicable Crusher Type: Impact Crusher
3.2 Definition and Application:
The Blow Bar is a key impact component mounted on the rotor of an Impact Crusher. It crushes materials through high-speed rotational impact, suitable for medium to low hardness materials such as limestone, concrete, and construction waste.
3.3 Advantages:
- High impact toughness, strong fracture resistance
- Large reduction ratio, uniform product size
- Easy to replace, low maintenance cost
- Suitable for both crushing and shaping processes
3.4 Common Materials:
- High Chrome Iron (Cr15‑Cr26)
