Abstract: The common problems such as blockage, abrasion, electrostatic, low transporting ability of pipe, and high density with long distance transporting in powder transporting are ordinarily existed. The methods of improvement, renewing the key transporting pipes, etc to solve the above mentioned problems were introduced. The thought of design, transporting principles and the applicable industry of the particular pipe were brought forward. 

Keywords: high-density; transporting technology of powder; particular pipe
