離心滾磨機的動態分析

Abstract

現今奈米等級合金的材料越來越多使用了，主要是一般合金材料研磨到奈米等級時，其物理性質會有不一樣現象，對於現今的科學很有幫助，因此如何將一般的合金材料研磨成奈米等級，是重要的技術,現今一般的物理性的研磨機，最主要的問題就是在研磨時會產生熱量，對研磨機及研磨粉末都不好的影響,需要額外的方法及成本,將熱量帶出或減少，因此在此前提下,研發出新的研磨機，是以行星式的方式設計其研磨機，研磨機上有研磨槽可將需要研磨顆粒放入，且研磨槽內有一研磨棒，當機台運動時，研磨槽會產生自轉及公轉，而研磨棒會在研磨槽內滾動且會產生的離心力，其離心力可以壓碎顆粒，達成研磨的效果。

Recently, a growing number of the engineering applications require the material of Nano-scale alloy. The main reason is that the physical property would be different when the normal alloy material is mill grinded into Nano-scale powder which is useful for current science. The most important skill is that how to grind the general alloy material into Nano-scale. For the current normal physical grinder the main problem is that grinding generates heat which has negative effect for grinder and powders. Additional methodology and cost are required to reduce or bring out the heat. For this reason, a new grinder with the planetary design is developed. The grinder has a cup with a hammer and the granule could be put in it. When the grinder is working, there is the rotation and revolution motion in the cup. The hammer is rolling in the cup and generating centrifugal force and then crumbling these granules.
