Study of residence time distribution and mill hold .Deze pagina vertalen

It is important to determine the residence time distribution (RTD) of a mill in order to predict the performance of the mill. In this study, the residence time distribution of a continuous centrifugal mill was measured experimentally by using aluminum powder as a tracer in a dry-grinding environment.

RESIDENCE TIME DISTRIBUTIONS IN BALL MILLS: .Deze pagina vertalen

The mean residence times indicate that some industrial mills are operated in the over–filled condition, leading to poor breakage conditions. Although all RTD's are somewhat similar on a dimensionless basis, there appears to be no consistent pattern to explain differences from one mill to another.

Residence time distributions normalized by mean residence time as a function of feed rate for centrifugal mill operated at G/D = 0.4, 60% ball filling, and mill revolution speed of 240 rpm. However, it was found that the shape of the RTD was changed somewhat with an increase in the mill revolution speed, as shown in Fig. 7 .

The engineers of DRAISWERKE designed a horizontal mill experiment to study the effects of product flow rate, agitator tip speed and slurry concentration on residence time distribution. The trials were performed on a 10-liter horizontal mill connected to two feed tanks and fitted with a g-ray emitter and scintillation counter to measure the solids concentration at the discharge pipe.

Residence time - WikipediaDeze pagina vertalen

The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
