Description

Technical Field

[0001] The invention belongs to the technical field of ball mills, and specifically discloses a ball milling device for preparing a silicon carbide ceramic-based composite material and a use method thereof. Background Art

[0002] Silicon carbide ceramic matrix composites are advanced materials that combine the high temperature performance, excellent mechanical strength and good chemical stability of silicon carbide ceramics with the high strength and high temperature resistance of silicon carbide fibers. Such materials have important application value in the field of wafer manufacturing because they can remain stable in high temperature environments, improve thermal processing efficiency, reduce maintenance costs, and increase equipment reliability and life.

[0003] Ball mills are mainly used to crush, mix and finely grind solid samples. They achieve the purpose of crushing and refining samples by high-speed rotation and collision and friction between the grinding media such as metal balls and agate balls loaded inside and the samples. The working principle of ball mills is based on mechanical action. When the equipment is started, the centrifugal force generated by its rotation makes the grinding media and samples move along a specific trajectory. The strong impact and friction force quickly reduce the sample particle size. Users can adjust the speed, grinding time and medium size according to their needs to adapt to the processing of samples with different hardness and particle size requirements.
