本文旨在改进橡胶、塑料、复合材料、金属、蜡等弹性材料的研磨工艺。如今，我们发现这些材料存在大量浪费。其中一些像塑料、人造橡胶复合材料对我们的环境非常有害。这项研究基本上有助于谨慎使用上述污染物。例如，热塑性塑料很难在环境温度下研磨小尺寸颗粒，因为它们会软化，粘附在块状物质中并堵塞筛网。在低温研磨中，当热塑性塑料被干冰、液态二氧化碳或液氮冷却时，它们最终可以研磨成适合静电喷涂和其他粉末工艺的粉末。这些工艺的优点是通过优化粒度、消除研磨机内的结块产品、增强对惰性研磨气氛造成的火灾和产品氧化的防护来提高生产率。
The paper aims in improvisation of the grinding process for elastic materials like rubber, plastic, composites, metals, waxes etc. Nowadays, we find a lot of wastage of these materials. Some of them like plastic, artificial rubber composites are very much harmful for our environment. This research will basically help in cautious use of the above mentioned pollutants. For example, Thermoplastics are difficult to grind small sized particle at ambient temperature because they are soften adhere in lumpy masses and clog screens. In cryogenic grinding when thermoplastic is chilled by dry ice, liquid carbon dioxide or liquid nitrogen they can be finally grounded to powder suitable for electrostatic spraying and other powder processes. Advantages of these processes are to increase productivity through optimized particle size, elimination of caking product within the mill, increases protection from the fire and product oxidation due to inert milling atmosphere..
