Abstract - Research work related to metallurgy and
mechanical department deals with the study of various ferrous and nonferrous materials. Usually properties of these materials enhance at microscopic level. These changes in properties have numerous applications. But in order to carry out research activities there must be ample supply of Nanopowder at low cost. Unfortunately this is not the case. The Nanopowder now obtained is produced through high energy planetary ball milling machine. The cost of this machine is high. Also the amount of powder produced is more .Our effort in this project is to minimize the production cost of Nanopowder by providing alternate machine. The major advantages of this machine include lower floor space, low initial cost. Also the quantity of nano powder required for testing is usually less. So the above mentioned machine can be used effectively Key Words: Ball milling, Cost effective, Nanopowder
ball milling, has been widely exploited for the synthesis of various nanomaterials. Various types of high-energy milling equipment are used to produce nanopowder. They differ in their capacity, efficiency of milling and additional arrangements for cooling, heating, etc. 1. SPEX shaker mills 2. Planetary ball mills 3. Attritor mills. These methods although cheaper than the chemical method but still are very high priced. Hence in this project we have developed a machine which will manufacture nanopowder cheaper than the above mentioned methods. A principle of high-energy ball milling is used in order to produce nanopowder. Our project is beneficial to most of the educational institutions to carry out research work related to nanotechnology. It is a simple process and does not include working with hazardous chemicals.

1. INTRODUCTION Nanotechnology is the science that deals with matter at the scale of 1 billionth of a meter (i.e., 10−9 m=1nm), and is also the study of manipulating matter at the atomic and Molecular scale. A nanoparticle is the most fundamental component in the fabrication of a nanostructure, and is far smaller than the world of everyday objects that are described by Newton’s laws of motion, but bigger than an atom or a simple molecule that are governed by quantum mechanics. In general, the size of a nanoparticle spans the range between 1 and 100 nm. There are several Synthesis methods for creating nanoparticles like, Physical vapor deposition, Chemical vapor deposition, Sol-gel Method, RF Plasma Method, Pulsed Laser Method, Thermolysis and Solution Combustion Method. But these methods are Very costly, so comparatively cheaper method has to be developed. Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience. Various different processes have been developed for the commercial production of nanomaterials. Among all top down approaches, high energy
