    After the dust and ignitor were placed in the chamber, the hinged top was closed and bolted, and then the chamber was partially evacuated to an absolute pressure of 0.14 bar,a. Then a 0.3-s blast of dry air (fiom a 16-L reservoir at 8 to 9 bar pressure) dispersed the dust and raised the chamber pressure to about 1 bar,a at ignition.

    The drying of the concentrates should also receive careful study, and no concentrates should ever be so dry that there is danger of loss in transit from dusting. The finer the concentrate the more water must be left in it to prevent this. It is much better to pay freight on a little water than to lose valuable concentrate in the form of fine dust.
