What is the advantage of a low speed pulse phase transport?

An important development in pneumatic conveying technology is the emergence of low speed and plug conveying systems. These systems solve the problems of conveying delicate, granular and brittle materials and products such as plastic granules that form "streamers" in high-speed conveying systems. There are a number of commercial systems designed for low speed transportation. Most of these systems transport the product as a series of discrete plugs. All these systems have special peripherals to use the required power regime.
