Sludge moisture reduction through the use of manufacturer internal reserves ("MALTSOVSKIY PORTLANDCEMENT" COMPANY)
In this article is pointed out that the wet cement production has a significant disadvantage which reduces the competitiveness of this material, significant energy costs for the evaporation of water and overheated steam in the firing process. Reduction of moisture content of raw sludge solves the problem of high production costs to some extend. This is achieved through the use of supplements-liquefiers, preliminary heat treatment clays, using slag, ash and nepheline sludge with low water demand
