For ball milling, you can assume a porosity of about 0.35 to 0.40 (the volume of space between the balls) and you can normally assume the pulp surface level is equal to the ball charge surface level. So do a crash-stop and measure the volumetric filling of the charge, then multiply that volume by 0.35 or 0.40.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
