Practical 1 : Ball Milling TF Lab 1

2013. 12. 23.  We have cutting methods, impact method, compression method and attrition method. Ball mills uses combined impact and attrition methods. In this experiment, we are required to break the coarse salt down using a ball mill and then by using a sieve, the particle size distribution is known. Method: Materials: Coarse Salt. Apparatus: Ball milling machine
