(
China Coal Research Institute Tangshan Branch ,Tangshan 063012 , China)
Abstract :In order to meet the new demand from dense medium coal prepreration plants , computational electro2
manetics arithmetic and it tools were introduced to the magnetic - system design field. Using this method a new
type magnetic system had been developed. The design level and quality were greatly improved to meet interna2
tional level with this method by practice. It paved the way for TDC1030’s successful development.
Key words :high - efficient ; magnetic separator ; magnetic - system design ; computational electromanetics

Study on Quick Shield Advancing System by Programmed
Complete Hydraulic Control
WEI Yong - gang , YANG Bao - liang , WANG Ming - pu
(
Taiyuan Branch of China Coal Research Institute , Taiyuan 030006 ,China)
Abstract :By analysing of the relationship between pump station flow and shield leg in the domestic traditional
shield control system , gives out an economic programmed complete hydraulic control , which will attain a quick
shield advance under a non - electric - hydraulic control. A brief description is done to the characteristics of
the system and its elememts.
Key words :advancing rate ; flow ; programmed control ; shield lower and advance interlock
