Application of carbonaceous calcium mud rook in cement raw material

Abstract

An application of carbon calcio-pelite in preparing cement is disclosed. Said cement is prepared from said carbon calcio-pelite (40-50%), lime stone (45-55%) and Fe correcting material (3.5-6%). Said carbon calcio-pelite can replace clay, part of lime stone, and coal.

Description

technical field [0001] The invention relates to a kind of cement, in particular to a kind of cement produced by using carbonaceous calcium mudstone as the main raw material. Background technique [0002] The traditional cement production ingredients are limestone, clay, anthracite, iron raw materials and mineralizers, among which the clay is first dried before use, and then processed into cement clinker after grinding and calcination. The clay in the raw material needs to be dried, which not only increases the investment in the configuration of drying equipment, but also increases the electricity consumption and coal consumption; the anthracite in the raw material is due to the high price of coal, and the production of cement is high energy consumption. The cost of cement has increased significantly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of cem...
