Analisa Sifat Magnetik Dan Komposisi Partikel Pasir Alam Sungai Rokan Provisi Riau Sebagai Fungsi Waktu Optimum Ball Milling

---

The ball milling time affects the magnetic properties its product. Research on the
magnetic properties and the product composition of natural sand of the Rokan
River as a function of optimum time in ball milling has been done . The natural
sand samples of Rokan River that has collected with a mass of 10 Kg were dried
under the sun ray before the separation process between magnetic and nonmagnetic
particles using an Iron Sand Separator (ISS). The result of the separation
with the Iron Sand Separator is called product of ISS. The product of ISS was
milled as a function of time of 60 hours, 70 hours, 80 hours, 90 hours, 95 hours,
100 hours, and 105 hours with 16 pieces of iron balls that has 1.5 cm in diameter.
The product of the ball milling then separated using Neodymium Iron Boron
(NdFeB), the result of this separation is called ball milling product (BM product).
The results of this research indicate that the magnetic induction values of natural
samples of Rokan river, ISS product and BM product in the ranged from 12,338-
14,849 mT for the same current of 1000 mA, while the magnetic susceptibility
values obtained in the range 3393,950-24436,437× 10-5. The identification of
element content in natural sand was done using X-Ray Fluorescence (XRF) for
ball milling product (BM product) as a function of time of 95 hours, 100 hours,
and 105 hours. The results of XRF identification showed that the composition of
Fe increased from 30.043% to 55.082%, while the composition of Si decreased
from 36.715% to 25.434%. The results of research showed that the optimum time
for the ball milling method was 100 hours.
