Equipment Overview
A high-consistency refiner with a self-weight of 8 tons generates significant vibration during operation due to the relative movement between the high-speed rotating rotor disc and the stationary stator disc, as well as the impact of fibers and mechanical transmission forces.
These vibrations can cause unstable clearance between the refining discs, affecting the uniformity and efficiency of fiber refining. Therefore, an effective vibration isolation solution is required to improve equipment stability and processing performance.
Vibration Isolation Solution
Based on the operating conditions and vibration characteristics of the equipment, ALJ-33 Series Metal Rubber Vibration Isolators are recommended.
The refiner weighs 8 tons and is supported by 8 vibration isolators. After accurate load calculation, the ALJ-33218 model was selected. Each mounting point carries approximately 1,500 kg, which is within the optimal load range of this model, ensuring effective vibration isolation performance.
If more installation holes or higher lateral stability are required, the ALJ-33268F model can also be selected. This model features multiple mounting holes, a wider load range, and higher lateral stiffness, helping the equipment operate more smoothly under dynamic conditions.
Key Product Advantages
1. High-Performance Natural Rubber Isolation Element
The vibration isolating element adopts high-quality natural rubber, featuring excellent resilience, high tensile strength, and long service life.
Performance Index | Specification |
Rubber Hardness | 60°（±5°） |
Rubber Density | 1.1Kg/m³ |
Elongation at Break | ≥300% |
Tensile Strength | 12MPa |
2. Reinforced Cross-Groove Structure
The unique cross-groove design improves the strength of the metal housing, enhancing durability and ensuring reliable long-term operation under heavy loads.
3. Integrated Center Tube Design
The center tube is manufactured as a one-piece component with high structural strength. The strong riveting process prevents loosening or separation during continuous operation.
4. Corrosion-Resistant Metal Housing
The thickened chrome-plated metal casing provides excellent rust and corrosion resistance, making the isolator suitable for demanding industrial environments.
5. Easy Installation Design
The mounting holes are designed as elongated slots, allowing easier alignment and installation adjustment during equipment setup.
