Jan 11, 2007· The two main categories of pneumatic conveying technologies are low-pressure (dilute-phase) and high-pressure (dense-phase) systems. Utilizing air pressure under 15 psig, the first category uses either positive or negative pressure to push or pull material through the convey line at relatively high velocities (see Figure 1).
get pricePneumatic conveying - Dense phase pressure conveying - Pressure vessel. Rate: 2 to 100 t./h. Conveying of products with high abrasiveness This dense phase pressure conveying is convenient for very abrasive products.This equipment ensures slow and delicate transport of granules, powders and mixtures, with less compressed air and energy consumption.
get priceDense phase pneumatic conveying involves the transfer of powders, granules, and other dry bulk materials through an enclosed pipeline. In dense phase conveying, particles are not suspended in the conveying air and are transported at high pressure and low velocity. This results in a more gentle delivery process for the products being conveyed.
get priceDense phase systems convey materials at slower velocity than traditional dilute phase pneumatic systems. Unlike dilute phase conveying, in which all the material is suspended in a high speed gas stream, dense phase conveying moves material in a slower but more concentrated manner, especially along the bottom of the pipeline.

get priceJun 16, 2014· While a number of parameters will influence the performance of a pneumatic conveying system such as air flow rate, solids flow rate, pressure drop, equivalent length of the pipeline, solids concentration, and others, it is the gas velocity in the pipeline that is the key parameter for dense phase conveying.
get priceThe difference between dense phase conveying and dilute phase conveying is that, in the case of dense phase conveying, solid to air ratio is high (above 12) (i.e) and 1 kg of air or conveying medium is used to convey more of the solids. Normally, the three phases are represented as follows: Dilute Phase = solid to air ratio up to 6; Medium ...
