As the core component of crushing equipment, the rotor is subjected to multiple tests of material impact, wear and alternating stress during long-term high-load operation. Whether it is a hammer crusher, impact crusher or impact crusher, the health of the rotor directly affects the crushing efficiency, energy consumption level and production stability of the equipment. For rotors with reduced performance due to wear, cracks or imbalance, professional repair services can not only restore equipment efficiency, but also save users up to 60% of replacement costs. As a rotor manufacturer, we have been deeply involved in the industry for many years and provide you with scientific and efficient rotor repair solutions.
Analysis of common causes of rotor damage
1. Wear and corrosion
Long-term processing of high-hardness materials (such as granite, iron ore) or corrosive substances (such as salt in construction waste) will cause the surface of rotor hammers, liners, throwing heads and other components to wear, deform or even fall off, reducing crushing efficiency.
2. Fatigue cracks
The rotor is subjected to cyclic loads during high-speed rotation (usually up to 800-1500 rpm), and stress concentration areas such as welds and bolt holes are prone to cracks, threatening the safe operation of the equipment.
3. Dynamic balance failure
Failure to calibrate the dynamic balance after local wear or component replacement will cause the rotor to vibrate more, accelerate bearing wear, and even cause equipment resonance.
The value of professional repair: Why choose repair instead of replacement?
1. Significant cost savings
The cost of a new rotor usually accounts for 30%-50% of the total price of the equipment, while the repair cost is only 40%-60% of the replacement cost. For large-scale mining equipment, a single repair can save hundreds of thousands of yuan.
2. Shorten downtime
The repair service adopts a standardized process and relies on mature technical solutions. The repair cycle is shortened by more than 50% compared to customizing a new rotor, minimizing production losses.
3. Performance optimization and upgrade
Material upgrade: Wear-resistant alloy hardfacing, coating and other strengthening processes are used for wear areas, the hardness is increased by 2-3 times, and the life is extended by 30%-50%.
Structural improvement: optimize the hammer arrangement angle according to the material characteristics, add wear-resistant guard plates, improve the crushing ratio and throughput.
Strict repair service process: scientific and rigorous, fully controllable
1. Damage assessment and solution customization
3D scanning detection: obtain rotor geometric size deviation, wear amount and crack depth through laser measurement.
Material analysis: Spectral detection of matrix material composition, matching the best repair process.
2. Core repair technology
Wear-resistant layer surfacing: use advanced hardfacing technology to repair the wear area and improve the surface hardness.
Crack repair: ensure the quality of the weld.
