Working up to 10 times faster than conventional laboratory ball mills (sometimes referred to as jar mills or pebble mills), the lab Attritor has a compact, vertical profile, requiring minimal space, and can be equipped or retrofitted easily and inexpensively with a variety of components and accessories.
Fritsch Planetary Ball Mills are perfectly designed for a variety of lab needs. Ideal for wet and dry combination of hard, medium hard, brittle and fibrous materials. Grind from a few milligrams to several kilograms into less than nano size.
Ball Mill Scale up by this method is known as collision energy based population balance model. The appropriateness of this model is shown for 38 cm ball mill. Comminution in ball mills account for a significant amount of power consumption in mineral processing plants. Therefore, accurate modeling of the process is extremely important to optimize the power consumption, which can lead to

The scale up method of planetary mill will be proposed in this section based on the impact energy. The impact energy, E i, which was defined by Eq. , in the virtual planetary ball mill was calculated from the simulation to clarify the effects of the diameter of the pot, d M, the depth, h,
Laboratory Ball Mills; Ball Mills use grinding media in spherical or cylindrical shapes in rotating containers to grind a wide range of material types to very fine sizes. Jars and grinding media are available in a wide variety of material types to optimize performance characteristics for long term wear resistance, low contamination levels, or
Speed up your synthesis lab Planetary Ball Mills as a tool in organic synthesis . prove that large scale Planetary Ball Mills operate more efficiently. Although, the net power input is higher for those the efficiency is significantly increased, thus from a relative point of
Apr 03, 20130183;32;Figure 1. Planetary Mono Mill PULVERISETTE 6 premium line. Planetary Ball Mills. Planetary ball mills are the most commonly used ball mills in laboratories for preparing samples ranging from soft to hard to brittle and fibrous materials.
The rule of thumb for mill scale up is approximately 1 (D/d) where d is the diameter of the smaller mill and D the diameter of the larger mill. So going from a 12quot; lab scale mill to a 24quot; mill, 1 (24/12) = 0.4, so the larger mill may perform as much as 40% more efficiently.
The objective of this paper is to investigate the scale up method of the planetary ball mill by the computational simulation based on Discrete Element Method.

In this work, a scale up model for describing this ball milling process is developed. The thesis is a combination of experimental and modeling efforts. Initially, Discrete Element Model (DEM) is used to describe energy transfer from milling tools to the milled powder for shaker, planetary, and attritor mills.
