Ball Milling A Green Technology For The Preparation And
the effect of ball mill on the morphological and structural features of cellulose has been described by okajima and co-workers. they treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for hours in dry and wet conditions with three solvents they observed that however, the ball mill has the disadvantages of low working efficiency and high energy-consumption. To improve the grinding performance, the ball mill load must be tweaked to levels where the plant can get desired product size and maximum production rate. however, the ball mill load is difficult to be detected by instruments directly.wet milling. the most common method of producing nanoparticles, wet milling is a more effective milling technique than the well-known dry milling. media milling is known as the classical wet milling technique; this process treats a dispersion of concentrated drug in an aqueous or non-aqueous liquid medium with milling balls.
