Introduction
GB/T 35150.1—2017 Standard Background and Significance
GB/T 35150.1—2017 is a technical requirement for new dry process cement production equipment, which mainly stipulates the composition, technical indicators and safety and environmental protection requirements of the raw material preparation system. The formulation of this standard aims to improve the production process level of the cement industry and ensure that the equipment performance meets the requirements of high efficiency, energy saving and environmental protection.
Comparison of raw material preparation system frameworks
| Dimensions | Traditional process | New dry process | Innovation |
|---|---|---|---|
| Equipment composition | Mainly single grinding equipment | Integrated grinding, powder selection, dust removal and other multifunctional systems | Modular design to improve production efficiency |
| Energy consumption indicators | High energy consumption, lack of energy efficiency management | Energy-saving equipment is widely used, and energy efficiency indicators are clear | Energy efficiency limit value increased by 30% |
| Environmental protection requirements | Low dust removal efficiency | Adopt high-efficiency dust removal equipment to meet emission standards | Particulate matter emission concentration ≤50 mg/m³ |
Technical requirements and implementation suggestions
Case analysis: Upgrading the raw material preparation system of a cement plant
Background:The original equipment of a cement plant had high energy consumption and low dust removal efficiency, which could not meet environmental protection requirements.
Solution:Adopt a new dry process, introduce a vertical roller mill, a high-efficiency powder concentrator and a bag dust collector. Energy efficiency management is achieved through an intelligent optimization control system.
Implementation effect:The system energy consumption is reduced by 20%, the particulate matter emission concentration is reduced to 35 mg/m³, and the production efficiency is increased by 15%.
Performance test and acceptance criteria
According to the standard requirements, the performance test of the raw material preparation system shall cover the following contents:
- Raw material moisture content: target value ≤0.5%
- Raw material particle size: in accordance with GB 2007.7
- Raw material fineness: 80μm square hole sieve residue 14%~18%
- System output: target value ±5%
- Energy efficiency test: in accordance with GB/T 26282 requirements
Implementation suggestions
Equipment selection:Prioritize energy-saving and high-efficiency equipment, such as vertical roller mills and roller presses.
Installation and commissioning:Strictly carry out single machine test, no-load linkage test and load test in accordance with the standard requirements.
Operation and maintenance:Establish a regular inspection system to ensure the normal operation of equipment lubrication and control systems.
Environmental management:Equipped with high-efficiency dust removal devices and regularly monitor emission indicators.
