Title:
METHOD FOR SUPPRESSING FACILITY DISORDER DUE TO MINERAL RAW MATERIAL
Document Type and Number:
Japanese Patent JP2022156426
Kind Code:
A
Abstract:
To provide a method for suppressing facility disorders due to a mineral raw material by suppressing natural oxidation and heat generation of the mineral raw material having a particular water content and particle diameter during transfer and storage of the mineral raw material and improving handling of the mineral raw material during the transfer and storage.SOLUTION: A method for suppressing facility disorders due to a mineral raw material comprises a contact step of bringing a polymer dispersant into contact with a mineral raw material including 70 wt.% or more of a particle having a water content of 1 to 30 wt.% and a particle diameter of 8 mm or less to obtain a dispersant-containing mineral raw material. In the contact step, the mineral raw material and the polymer dispersant are brought into contact with each other so that a particle diameter of 95 wt.% or more of the polymer dispersant after the contact step is 110% or more and less than 500% relative to an average of the particle diameter of the polymer dispersant before the contact step and a water content of 95 wt.% or more of the dispersant-containing mineral raw material after the contact step is 1 to 12 wt.%.SELECTED DRAWING: None
