Markham's successful development of technology based on the use of low-pressure blowers extended the scope of pneumatic stowing and led to its adaption to the production of efficient conveying systems for the mining industry.
In pneumatic stowing, a high terminal velocity is necessary to ensure good compaction, whereas in conveying the aim is to achieve a low terminal velocity consistent with preventing fall-out which could result in pipe blockage.
