Ultrasonic modification of alumina powder during wet-ball milling
Materials Letters, 1996The comminution of unagglomerated alumina powders was enhanced by applying ultrasonic energy during wet-ball milling for 16 h. The resulting powders had significantly finer mean and median particle sizes, narrower particle-size distributions, and less angular morphologies than powders which were conventionally wet-ball milled.

Suspension rheology during wet comminution in planetary ball mill
Chemical Engineering Research and Design, 2008Obtaining and controlling desirable system behavior in terms of rheology is important issue in many engineering problems. This study monitors rheological behavior of dolomite suspensions produced by wet comminution in planetary ball mill. Dolomite has a number of uses, in agriculture, steelmaking, glass making, ceramic industry, pharmaceutical industry

The Scalability of Wet Ball Milling for The Production of Nanosuspensions
Pharmaceutical Nanotechnology, 2019Background: Miniaturization of nanosuspensions preparation is a necessity in order to enable proper formulation screening before nanosizing can be performed on a large scale. Ideally, the information generated at small scale is predictive for large scale production.

An overfilling indicator for wet overflow ball mills
Minerals Engineering, 2016The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.

Biotechnology and Bioengineering, 1990
AbstractSimultaneous wet milling and enzymatic hydrolysis of newsprint in a ball mill reactor (BMR) and in an attrition mill reactor (AMR) were studied. The effect of milling on the enzyme deactivation was also investigated. Variables studied included milling media size, material, and the presence or absence of an air–liquid interface in the reactor ...

Effect of ball size and powder loading on the milling efficiency of a laboratory-scale wet ball mill
Ceramics International, 2013Abstract Alumina powder was wet-milled by zirconia balls with varying diameter at varying rotation speed, and the resultant particle size of the milled powder was analyzed. At a given rotation speed, there exists an optimum ball size to yield minimum particle size of alumina. The optimum ball diameter decreases as the rotation speed increases.

Kinetics of fine wet grinding in a laboratory ball mill
Powder Technology, 2001Abstract The kinetics of batch wet grinding of quartz from a feed of 600×425 μm to a product of 80% less than 8 μm have been determined using sieving and laser diffractometer sizing for size analysis. A dispersing agent was added while proceeding to longer grinding times to prevent particle agglomeration in the mill.

Grinding kinetics of quartz and chlorite in wet ball milling
Powder Technology, 2017Abstract Under an invariant and self-similar mill environment, batch wet grinding studies were carried out by grinding mono-sized fractions of quartz, chlorite and their binary mixture at different blending ratios. The results obtained indicate that the breakage behavior of both minerals as well as their mixture followed a first-order model.

A Quantitative Treatment of Size Reduction in Wet Ball Millings
Drug Development and Industrial Pharmacy, 1979AbstractThe decrease in geometric mean particle size during wet ball milling follows a reciprocal relationship, which predicts an initial rapid rate of comminution, followed by a slow rate of reduction which develops into a situation where the mean particle size virtually remains constant.

Acceleration and deceleration of breakage rates in wet ball mills
International Journal of Mineral Processing, 1992Abstract Wet grinding is a nonlinear process and hence, estimation of breakage rates based on the linear model cannot be strictly used. Also the use of a functional form for breakage rates in an estimation scheme can produce artificially unrealistic values.
