Nelson said that the farm traced these costs each month and summarized them after each stage in the process: harvest, wet milling, dry mill. "Other than the costs outlined above, some factors or categories that we need to consider when calculating production costs are informal labour agreements (ie, family labour, non-contractual work)," he added.

A method for increasing the bulk density and decreasing the time of wetting with water of a substantially anhydrous kaolin clay powder, comprising dry ball-milling the said powder using work inputs of from about 5 to about 40 HP-hrs/ton of dry clay, followed by pulverization in a high energy impact mill and classification to eliminate undesirable larger particles.
Indirect rotary or vibrating grate dryers are used to dry ball clay. Combustion gases from the firebox pass through an air-to-air heat exchanger to heat the drying air to a temperature of approximately 300°C (570°F). The clay is dried to a moisture content of 8 to 10 percent. Following drying, the material is ground in a roller mill and shipped.
