研削 mill is very important powder production equipment. In recent years, manufacturers have made great efforts to reduce the noise of grinding mills. However, restricted by various factors, the vibration and noise of grinding mills have not been fundamentally solved. Vibration is the main reason that causes noise of grinding mill, so vibration control not only can protect equipment and operators from being harmed, but also can effectively reduce the noise pollution. In this article, we mainly talk about reasons and solutions about vibration and noise in grinding mill.

グラインダーにおける振动と騒音発生の原因

粉砕机の騒音は、材质、製造、部品の设置だけでなく、粉砕机の构造设计とも密接な関係があります。粉砕机における振动と騒音の発生原因は以下の通りです。

  • 1. Improper structural design and insufficient working accuracy lead to vibration and noise in the grinding mill.
  • 2. The deviation in the roller manufacturing causes the radial runout, leading to the unstable running of grinding mill, which causes the vibration. If the roller does not get adjusted, in the grinding process, the unstable operation will also produce noise.
  • 3. ローラの加工誤差と材質のばらつきがローラの不平衡の原因となり、その結果、粉砕機が振動します。
  • 4. The low positioning accuracy of the roller bearing, the improper selection or adjustment of the bearing, and the unreasonable structural design of parts matched with the bearing will all reduce the rotation accuracy and service life of the bearing. In this case, the grinding mill works with load and its noise will also rise.

Besides, during operation, uneven heating of the roller and variable grinding force will cause the roller to bend and deform.

粉砕机の振动および騒音に関する解决策

The vibration and noise reduction solutions for the grinding mill are mainly formulated according to its structural design.

  • 1. ローラ軸受の配置設計の最適化。ローラ軸受とローラ軸の端部に円錐接続を採用することで、ローラの回転精度を高め、騒音の低減を図る。
  • 2. ローラの剛性と強度を高め、共振を抑制する。
  • 3. Strictly control the installation accuracy. While installing the spare parts, operators should strictly follow the rules. Make sure the grinding mill is well lubricated to reduce noise.
  • 4. 給餌装置と本体の振動を最適化する。
