Bead Mill: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Grinding Volume The grinding volume available for the material	0.0 L	Positive
◙ Max Grinding Volume The maximum grinding volume the vessel can handle	275.0 L	Positive
○ Packing Density The packing density of the beads within the vessel	85.0 %	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Grinding Volume and the system computes the Number of Units and the Grinding Volume.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Grinding Volume.

For more information on the sizing of the bead mill, see Bead Milling: Modeling Calculations.

Costing

The purchase cost of the equipment is based on the grinding volume. By default it is calculated by the programs built-in model for a bead mill with a minimum volume of 1 L.
