High-Efficiency Crusher Wear Parts List: Which Accessories Must Be Stocked Regularly?
Core List: These Five Types of Accessories Must Be Stocked Regularly
| Part Name | Core role | Recommended stock quantity | Signs of Change |
| 1. Hammer blades (the “teeth” of a crusher) | The core component that directly crushes materials experiences the fastest wear. | At least 1 set (same number as rotor hammers) | Significantly decreased output, coarser finished particle size, abnormal current fluctuations. |
| 2. Screen (a sieve used to control particle size) | It controls the finished product particle size to ensure crushing quality. | 2-3 pieces (different common bore diameters) | Poor material discharge, reduced output, uneven particle size, screen damage. |
| 3. Bearings (the “joints” of the rotor) | It supports the high-speed rotation of the rotor; damage to this component can lead to serious malfunctions. | 1 set (including spindle bearing and seals) | Increased machine operating noise, abnormal machine vibration, excessively high bearing housing temperature. |
| 4. Belt (power transmission belt) | It transmits power from the motor to the crusher’s main shaft. | 1-2 sets | Machine stalling, low transmission efficiency, belt cracks or abnormal wear. |
| 5. Seals and small screws (the “unassuming” key components) | It prevents powder leakage and ensures secure component connections. | Several | Dust leakage, loose screws causing unusual noises. |

[Manufacturer Exclusive] Parts Selection and Maintenance Recommendations
Hammer Blades: Wear-resistant, but also requires proper “use.”
o Selection: Choose hammer blades manufactured using high-frequency quenching or tungsten carbide welding processes, which can increase wear resistance by more than 50%.
o Usage: Strictly adhere to the principles of group replacement and symmetrical installation to maintain rotor dynamic balance and avoid machine vibration.
Screen: Choose the right aperture and material
o. Selection: Choose the aperture size based on the target particle size. For highly abrasive materials (such as palm shells), a thickened screen made of manganese steel is recommended.
o. Usage: Ensure the screen is taut during installation to prevent vibration that could lead to premature fatigue and breakage.
Bearings: Ensuring proper lubrication is crucial.
o Use bearings from well-known brands for more stable quality.
o Use the specified high-temperature lithium-based grease regularly and in appropriate amounts. Do not use excessive amounts, as this can cause the bearings to overheat.
