Batch Ball Mills Option

If you are unsure of the size ball mill you may need, but you know the quantity of product you would like to process in each batch, then there are a couple of things you need to know.

First, ball mills are understood by the total volume in the cylinder when it is empty; This volume is based on the ball mill's diameter and the cylinder's length from the inside (refer to the Chart below for sizing). As a rule of thumb, 25% of the total volume of the ball mill is considered the "working" part of the ball mill.

Next, know that proper filling of the ball mill proportionately between the grinding media and the product depends on whether your process is wet or dry.

Dry process example:

• 200-gallon mill
• 100-gallon grinding media
• 50-gallon product
• 50 gallons of working space

Wet grinding is a little bit different and varies tremendously based on the viscosity of the liquid, the ability of the solids to coagulate in the solution, the number of solids in the liquid, the introduction of wetting agents to disperse the solids, and whether or not the solids are organic versus non-organic.

Typically, the product fill line for wet milling is between 25% and 65% of the ball mill's total volume, but this is just a generality for argument's sake.
