Abstract:
Ball Milling is a tool that plays an important role in synthesizing magnetic nanoparticles
from natural sand. The purpose of this research is to design and do the experiment of a
Ball Milling machine. Our effort in this research is to minimize the cost of synthesis of
magnetic nanoparticles by providing alternative machine. The advantages of this
machine include simple, efficient and low cost production. In order to synthesis
magnetic nanoparticles, then the natural was inserted into ball milling tube with several
balls in it and rotates continuously. In the tube the balls will collide with each other. As
a result of this ball collision, the sample that is inserted into ball milling tube is caught
between the balls. The particles inside the ball milling tube break off so on until the
particle size reaches the desired size. Testing of the Ball Milling machine was done
using natural sand samples from the Arta beach Pariaman West Sumatera as function of
milling time such as 10 hours, 20 hours, 30 hours and 4o hours using milling ball size of
1,5 cm. The magnetic properties studied were magnetic induction, magnetic
susceptibility and mass susceptibility and magnetic degree. The results shown that
increase in milling time decreased particle size of the sample and therefore, incease the
value of magnetic susceptibility decrease the magnetic degree
