Enzymatic saccharification (Hydrolysis) is one of the technologies to hydrolyze lignocellulosic biomass. In this study, Bangladeshi bagasse is used as feedstock for enzymatic saccharification and ethanol fermentation. Cutter mill and Mechano-chemical treatment (Ball mill) are used for pretreatment. The main objective of this study is to investigate the effect of substrate concentration, pretrea...

This study was designed to examine the physical disintegration of graphene (GN), an excellent heat conductor, by using the planetary ball mill, a simple and convenient means to produce particles arbitrarily. The conditions for the disintegration of GN were distinguished by the rotation of the planetary ball mill (200 rpm, 400 rpm, and 600 rpm) and by the duration of its operation (30 min, 60 mi...

Milling is a vital unit operation in various material processing operations and consumes around 2% of the energy produced in the world [1,2]. It dictates the cost economics of mineral, cement, power, pharmaceutical and ceramic industries. Grinding is an important unit operation for chrome ore pelletisation process. Chromite ore along with 5% coke is milled in the wet ball mill and filtered ore ...

In this work, a blend of Ti, Nb, and Mn powders, with nominal composition 15 wt.% Mn, balanced Ti Nb wt.%, was selected to be mechanically alloyed by the following two alternative high-energy milling devices: vibratory 8000D mixer/mill® PM400 Retsch® planetary ball mill. Two ball-to-powder ratio (BPR) conditions (10:1 20:1) were applied, study evolution synthesized phases under each mechanical ...

A detailed mathematical analysis is presented to advance the current understanding of the mechanics of milling operation in a planetary ball mill in terms of a global Cartesian reference space. The ab initio calculations have identified the role of milling parameters in determining the condition of detachment of the ball from the vial wall. The condition of an ‘effective’ impact has been identi...

This paper presents a solution for the detection and control of coal loads that is more accurate and convenient than those currently used. To date, no research has addressed the use of a grinding medium as the controlled parameter. To improve the accuracy of the coal load detection based on the kinetic energy of balls in a tubular ball mill, a Discrete Element Method (DEM) model for ball kinema...
