Abstract
A continuous dense phase conveying method and apparatus, for conveying large quantities of dry bulk material through a material conveying pipe, feed particulate material into the conveying pipe and supply a quantity of low pressure gas into the pipe to force particulate material to move therealong. A gas pressure within the conveying pipe is monitored. When this monitored pressure reaches a predetermined gas pressure level, a quantity of high pressure gas is supplied to the conveying pipe to force the particulate material to move continuously therealong.
