Loading : Period during which the mixer is filled with sand. During this period, the motor speeds increase from nominal speed to the necessary speed for lump breaking.
Dry Mixing : The sequence is designed to eliminate as many sand balls as possible from the sand and efficiently mix the additives. The tool speeds are increased significantly to achieve this.
Wet Mixing : This is the most important process phase. After adding the necessary water, tool speeds automatically self adjust as the sand properties are achieved resulting in optimized power input and '0' temperature increase.
Aeration : At the end of the preparation sequence and after the sand reaches its nominal characteristics, the speed ratio can be judiciously chosen to give well-aerated sand, extremely silky in touch and ideal for moulding fine parts.
Emptying : Sand is emptied from the mixer and the two motors return to their normal speed.
