Standard Bond Ball Mill Grindability Test Method-Procedure
The Wi value from this equation should conform with the motor output power to an average overflow ball mill of 8 ft. interior diameter grinding wet in closed circuit. For dry grinding the work input should normally be multiplied by 1.30. However, ball coating and packing can increase the work input in dry grinding.

Milling tests with the Fritsch Planetary Ball Mill
The Planetary Mill PULVERISETTE 5 premium line provides two stations of grinding bowls with 500 ml volume (largest capacity on the market). Each grinding bowl can be filled 1/3 part of the volume (± 170 gr sample). So, if we use two grinding bowls, the optimum capacity is about 170 x 2 = 340 g per milling process. 3.

WetBulb Globe Temperature
The WetBulb Globe Temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account: temperature, humidity, wind speed, sun angle and cloud cover (solar radiation). This differs from the heat index, which takes into consideration temperature and humidity and is calculated for shady areas.
