| Roller-bowl medium-speed coal mill is a commonly used coal grinding equipment. It grinds coal blocks by relative movement between rollers and bowl-shaped grinding discs. The Roller-bowl type medium speed coal mill seal ring ZGM113G plays a vital role in the roller-bowl medium-speed coal mill. The following is a brief introduction to this sealing ring: Structural features: 1. Composition: The Roller-bowl type medium speed coal mill seal ring ZGM113G is usually made of wear-resistant materials, such as rubber, polyurethane or composite materials, forming a closed ring structure. 2. Position: The sealing ring is installed between the roller and the fixed bearing, and between the grinding disc and the machine body to form a sealed space to prevent coal powder leakage and external impurities from entering. Function: 1. Sealing function: Mainly prevent the coal powder generated during the coal grinding process from leaking to the outside of the equipment, reducing environmental pollution, and avoiding lubricating oil pollution. 2. Protection function: Protect the bearings and other internal components from the invasion of coal powder and impurities, and extend the service life of the equipment. 3. Support function: In some designs, the sealing ring also plays a certain role in supporting the roller. |
| Technical parameters of coal mill Heat generation: 1631MJ/kg Surface moisture:< 18% Grindability system: HGI=4080 Combustible volatile matter: 1640% Raw coal particles: 040mm Fineness of coal powder: R90=240% |
| Product Features: 1. Reliability: Adopting high-quality bearing support and replaceable stationary wear rings. 2. Efficiency: The dual suction design improves suction efficiency. 3. Flexibility: Suitable for various industrial and municipal fields. 4. Stability: Maintain a high degree of sealing during operation, without leakage. 5. Maintainability: replaceable stationary wear rings and well-designed lubrication system. |
| Application: Thermal power plants: Coal mills are used to grind coal into powder for better combustion and power generation. Steel plant: Coal mills are used for the preparation of coal powder, helping to improve combustion efficiency. Cement plant: Coal mills are used for the preparation of coal powder to ensure the smooth progress of cement production. In the field of coal chemical industry, medium speed coal mills can be used in coal to oil, coal to fertilizer, coal to natural gas and other process flows to provide qualified coal powder. |
