Introduction
Interpretation of GB/T 35055-2018 National Standard of the People's Republic of China
1. Background and significance of standard formulation
GB/T 35055-2018 "Horizontal scraper unloading coal slime centrifuge" is managed by the National Coal Standardization Technical Committee and proposed by the China Coal Industry Association. This standard specifies the technical requirements and test methods for horizontal scraper unloading coal slime centrifuges in the field of coal slime dehydration treatment.
With the improvement of environmental protection requirements in the coal industry, coal slime recovery and dehydration efficiency have become key indicators. The formulation of this standard aims to unify technical specifications, improve equipment performance, and ensure safe production.
2. Comparison of standard framework and technical parameters
| Serial number | Item | Unit | Model | ||||
|---|---|---|---|---|---|---|---|
| WLL900 | WLL1000 | WLL1200 | WLL1300 | WLL1400 | |||
| 1 | Feed size | mm | ε~0 | ||||
| Processing capacity | t/h | 30-45 | 45-60 | 60-80 | 80-100 | 100-120 | |
3. Technical requirements interpretation
Material selection:High-quality carbon structural steel (GB/T 699), carbon structural steel (GB/T 700), ductile iron castings (GB/T1348).
Processing technology:Dynamic balancing test, wear-resistant protection treatment, welding requirements meet JB/T5000.3.
4. Test methods and inspection rules
No-load operation test:Not less than 4 hours, check the rotation flexibility, stability and amplitude (≤0.2mm).
Noise control:Should not exceed 85dB(A) to ensure compliance with environmental protection requirements.
5. Implementation suggestions
5.1 Equipment selection
- Select the appropriate model (WLL900 to WLL1400) according to the properties of the coal slime.
- Consider the processing capacity, feed concentration and external moisture requirements.
5.2 Operation and maintenance
- Regularly check the lubrication system to ensure that the oil pressure and temperature rise are normal.
- Monitor the gap between the screen basket and the spiral scraper (5-15mm) and adjust it in time.
5.3 Optimization Suggestions
- Low-temperature resistant lubricants can be used in cold regions.
- Regularly calibrate vibration and noise detection equipment to ensure accuracy.
