The paper introduces selection,effect after putting into operation,existing problems and reformation conditions of process equipments reconstruction plan of matched copper concentrate steam drying system,dry ore dense phase conveying system and flue dust dense phase conveying system of 350 kt/a expanding reconstruction project of Jinlong Company.

The Design and Realization of a Monitoring and Control System for Series Ⅲ Dense Phase Conveying;

For dense phase conveying of pulverized material there is a close relationship among many parameters, such as fluidization velocity, carrier gas flow rate, pipe diameter etc.

Technology of dense-phase transport was applied to pulverized coal injection system for BFs at Hangzhou Iron & Steel works,1991.

Some new techniques were adopted in injection system, shch as 2 tanks in parallel ,single pipe with distributor and dense phase transport.

dense phase pneumatic conveying control system based on fuzzy neural network;

The low speed, high efficiency dense phase pneumatic conveying equipments can solve the difficulties of the breakage of the materials, the blockage and abrasion of the pipelines and reduce the consumption of gas.

The effect of materiel factor on alumina hyper dense phase conveying;
