Rotary kiln mineralization agent and method for manufacturing same

Abstract

The invention discloses an increasing production and energy-saving rotary kiln mineralizer of cement, allocating raw material according to mass percent as: 0-5 wt grammite, 5-15 wt sanbornite, 5-45 wt dolostone, 5-15 wt fayalite, 10-40 wt zeolite and 0-10 wt flour. This invention also discloses a preparing method of rotary kiln mineralizer, which comprises by the following steps: bruising separately; mixing dosage; packing; getting end product.

Description

technical field [0001] The invention relates to a rotary kiln mineralizer and a manufacturing method thereof. Background technique [0002] Portland cement is a kind of hydraulic gelling substance, its properties depend on the mineral composition of cement clinker, among which tricalcium silicate (C 3 S), dicalcium silicate (C 2 S), tricalcium aluminate (C 3 A), tetracalcium aluminoferrite (C 4 AF) and other minerals. Since these minerals are composed of main oxides through high-temperature calcination, especially tricalcium silicate (C 3 S) It needs to be produced at a high temperature of 1350-1450°C. In addition, the cement production equipment is old and bulky, with high horsepower and low efficiency, which makes the cement industry a high energy consumption, large power and coal consumption, low utilization rate and high cost. Contents of the invention [0003] The invention provides a rotary kiln mineralizer capable of saving ene...

Problems solved by technology

Since these minerals are composed of main oxides through high-temperature calcination, especially tricalcium silicate (C 3 S) It needs to be produced at a high temperature of 1350-1450 ° C. In addition, the cement production equipment is thick, old and heavy, with high horsepower and low efficiency, which makes the cement industry a high energy consumption, high power consumption, large coal consumption, low utilization rate and high cost.
