Analysis of the magnetic susceptibility of the composition and particle size of the natural sand
of the Rokan River has been carried out using two-stage ball millng method.This study aims to
determine the value of magnetic susceptibility,percentage composition and particle size of
natural sand in the Rokan River which has been ball milled in two stages. The results of the
calculation of the magnetic susceptibility value using the two-stage ball milling method have
increased for the same current of 1000 mA, the magnetic susceptibility value for ball milling
stage 1 (𝐵𝐵𝑚1) is 32037.118 ร 10โ5and stage 2 ball milling (𝐵𝐵𝑚2) is 36084,843 ร 10โ5.
Identification of the composition was carried out using X-Ray Fluorescence (XRF) and particle
size testing using a Scanning Electron Microscope (SEM) for ball milling product stage 1
(𝐵𝐵𝑚2) and stage 2 (𝐵𝐵𝑚2) ball milling. The results of XRF identification showed that the Fe
composition increased from 18.510% to 20.039%, while the Si composition decreased from
51.329% to 50.093%. The results of the SEM test showed that with the two-stage ball milling
method the particle size decreased from 1.564 𝜇m in stage 1 ball milling and 1.353 𝜇m in stage
2 ball milling. |
