Embodiment Construction

[0009] The embodiment of method of the present invention and purposes are as follows:

[0010] First collect the pulpy waste produced in the wastewater treatment process of titanium dioxide production, press filter it, remove part of the water to make it into a block, and then dry the block to reduce the water content to 10%. SO in material 3 The content is about 38% to 40%. The dried material is crushed by crushing equipment to a granular or powdery particle size ≤ 10mm, which is the finished cement additive. The cement additive is used as a mineralizer and a coagulation regulator in the calcining and grinding processes of cement production, and its usage and dosage are the same as those of the original natural dihydrate gypsum mineralizer and coagulation regulator. In the grinding process of cement production, the above-mentioned cement additives are used as grinding aid carriers. The method of use is to fully mix and homogenize the cement additives and grinding aids accord...

Abstract

The invention relates to a method for producing cement adjuvant using industrial waste and uses thereof, wherein the production method comprises the steps of, filter-pressing the waste materials containing CaSO4, removing part of the moisture to obtain block-shaped material, subjecting the block-shaped material to seasoning, lowering its water content to 8-10 wt%, and making blocks from the dried materials, or disintegrating into granular form or powdery form.

Description

technical field [0001] The present invention relates to a kind of industrial waste (particularly the waste water that produces in the production of titanium dioxide is processed and contains CaSO2 4 The waste material) the method for producing cement additive and the purposes of this cement additive. Background technique [0002] In the calcination process of cement production, in order to improve the flammability of raw meal and complete the formation process of cement clinker faster, especially when the calcined lime has a high saturation coefficient or the raw material contains alkali and quartz sand in the raw material, the existing The technology usually requires the addition of natural dihydrate gypsum, calcium fluoride, phosphogypsum and other additives as mineralizers during the calcination process. In addition, in the grinding process of cement production, it is usually necessary to add a certain amount of dihydrate gypsum as a coagulant to improve the early streng...
