Dense phase pneumatic transmission<\/strong> is a material handling technique in which bulk materials are transported in a closed pipeline at low gas velocities and high material concentrations. This industrial transport method reduces material wear and degradation compared to traditional pneumatic transport. Dense phase technology is particularly suitable for sensitive and valuable materials over long transport distances.<\/p>\n\n\n\n

What is dense phase pneumatic transport and how does it differ from conventional pneumatic transport?<\/h2>\n\n\n\n

Dense phase pneumatic transfer works at low flow rates and high pressure levels, allowing the material to pass through the pipeline as a dense mass. Dilute phase transport, on the other hand, mixes the material with the air flow and moves at high velocities along the walls of the pipeline.<\/p>\n\n\n\n

The key difference between these techniques is the behaviour of the material in the pipeline<\/strong>. In a dense phase system, the material forms dense \u201dplugs\u201d or flows in a slow layer at the bottom of the pipe. This requires a higher pressure, but allows much lower gas volumes to be transported.<\/p>\n\n\n\n

Pressure levels for dense phase transport are typically 1-6 bar, while dilute phase systems operate at 0.5-1 bar. Flow velocities range from 3 to 15 metres per second, while dilute phase systems have velocities of 15 to 30 metres per second. This helps to preserve the properties of the material and significantly reduces wear in the piping system.<\/p>\n\n\n\n \n
