in this work, nanostructured niti shape memory alloy with equal atomic percentage was produced through mechanical alloying. the result exhibited that after 60 h of mechanical alloying of high purity elemental powder mixtures of nickel and titanium by a planetary high-energy ball mill, the ti dissolved into ni lattice and niti (b2) phase with was obtained. the xrd investigations, sem observation...

Ball mills are the leading grinding equipment in mineral processing industry. Balls primary component of materials. Lifters lift these balls to shoulder position before cataracts them toe position. Almost all classical theories do not consider lifter's geometry calculating energy consumption ball and focus only on fill level charge, lifter dimensions, their number, mill's rotational speed. To i...

The equations governing the motion of steel balls and their impact onto shell liners in industrial Semi-Autogenous Grinding (SAG) mills are derived in full details by the authors and are used in order to determine the effective design variables for optimizing the working conditions of the mill and to avoid severe impacts which lead to the breakage of SAG mill shell liners. These design vari...

Planetary ball mill is a powerful tool, which has been used for milling various materials size reduction. The discrete element method (DEM) was to simulate the dynamics of particle processes in planetary mill. This work includes calibration DEM parameters using EDEM Altair 2021.2 software, provides both faster workflows and results. iterative input changed close correlation between simulation e...

The present work was focused on investigation of effect of solution concentration, contact time and pH variation on ability of the eucalyptus, neem and mango leaves in removing chromium ions form aqueous solution. The dried leaves were washed with deionised water, air-dried and ground using ball mill then sieved. The leaf powder was added to 1M stock metal ion solution made from potassium dichr...

The grinding process has become widely used to improve the fineness and performance of fly ash. However, most studies focus on particle size distribution ground ash, while morphology is also an important factor affect cement paste. This article aims at three different kinds ash from ball mill vertical mill, observed by scanning electron microscopy (SEM) calculate spherical destruction (the rati...

Grinding/crushing is a process of reducing the size in crushing plant to get desired size. The coal ball mill technique where collides with feed on tube wall, thus cracks will form which result smaller Limitation problem this study effect speed time and grain resulting from milling process, mass sample used 500 grams sizes that do not pass 10 mesh sieve, there are three types pulley variations,...

Grinding aids are commonly used in grinding to disperse the material system effectively and improve performance. Most of time, different with varying dosages tested laboratory conditions by trial error. A simple methodology is required compare results batch milling. In this study, utilization modelling approach comparing effect aid types were aimed. order achieve this, an experimental program h...
