300MG41.11.02.96 Medium-Speed Coal Mill Elastic Sleeve: Core Shock Absorption Component

300MG41.11.02.96 Medium-Speed Coal Mill Elastic Sleeve: Core Shock Absorption Component

Description
The 300MG41.11.02.96 Medium-Speed Coal Mill Elastic Sleeve is a critical shock absorption and buffering component specifically designed for the core pulverizing equipment—the medium-speed coal mill—in large thermal power plants. Its model code precisely defines its application equipment, structural dimensions, and installation position, making it an indispensable "flexible joint" for ensuring the long-term stable and efficient operation of the coal mill. Operating in a harsh environment filled with high-hardness coal particles, impact loads, and continuous vibration, this elastic sleeve bears the heavy responsibility of absorbing shock, isolating vibration, and protecting key components.

Core Functionality: Mechanical Properties
The core function of this "elastic sleeve" lies in its unique mechanical properties. During operation, the grinding rollers in the medium-speed coal mill exert immense pressure on the coal blocks. Concurrently, the non-uniformity and varying hardness of the coal lead to severe, random impact loads. If these loads were entirely borne by rigid metal components, it would rapidly lead to metal fatigue, cracking, and even fracture.
The 300MG41.11.02.96 Elastic Sleeve is installed at the critical nodes of these shock transmission paths. Utilizing its excellent elastic deformation capability, it converts sharp impact loads into smoothed stress waves, absorbing most of the impact energy. This effectively protects more critical and expensive components such as the grinding roller shaft, rocker arm, and mill casing from damage.

Material Selection and Structure
In terms of material selection, this elastic sleeve must possess extremely high strength, excellent elasticity, and outstanding wear and aging resistance.
It is typically made of high-quality synthetic rubber and may be integrated with an internal metal bushing or an external metal frame through a special vulcanization process, forming a composite structure.
•    The rubber section provides the required elasticity and cushioning performance.
•    The metal section ensures installation stability and load-bearing capacity.
This composite material design allows it to withstand significant static pre-tightening forces while adapting to dynamic alternating loads.
