Abstract
The invention relates to the field of grinding aids and discloses a mineral powder grinding aid. The mineral powder grinding aid is prepared from the following raw materials in percentage by weight: 15-22% of triethanolamine, 5-15% of sodium stearate, 10-24% of polyacrylamide 5-10% of sodium hexametaphosphate, 5-10% of sodium pyrophosphate, 2-7% of sodium silicate, 1-5% of dihydrate gypsum, 0.5-1.2% of polytetrafluoroethylene and the balance of water. The invention provides the mineral powder grinding aid which is good in grindability and high in activity and aims at solving the problems of poor grindability and low activity of the existing commercial mineral powder grinding aids; after the mineral powder grinding aid is added, the grinding efficiency of the mineral powder is improved, the yield of the mineral powder is increased, the power consumption of grinding aid is reduced and the specific surface area of the mineral powder is increased.
Description
Technical field
The present invention relates to mineral grinding technical field, particularly a kind of breeze grinding aid.
Background technology
The main component of breeze is by CaO, MgO, Al
2o
3, MgO, SiO
2, MnO, Fe
2o
3deng silicate and the aluminate of composition.Under the prerequisite not changing original undertaking's production technique, use grinding aid, have and improve quality, increase yield, reduce costs, reduce effect of power consumption, improve effects.This is to the state of the art promoting breeze manufacturing enterprise, and strengthen the market competitiveness of enterprise, the development of promoting enterprise is significant.Breeze grinding aid is the needs produced according to breeze, and develop the new high-tech product successfully with independent intellectual property right, it is by physics, chemical twin effect, and a kind of composite powder material of special process processing.Breeze grinding aid is in breeze is produced, and the effect energy between energy dispersed material, reduces the poly-power between a material and resistance, eliminates machinery and keeps in obscurity, reach raising material specific surface area, reduce screen over-size, thus realize grind-aiding effect, exerting oneself of raising grinding machine.
Breeze grinding aid is in the market a kind of material with good lateral reactivity, and it has become the important sources of Cement industry active mixed material.Cement production enterprise uses breeze can expand cement type, improve cement performance (corrosion stability etc.).But breeze grinding aid grindability is in the market poor, and active not high enough, therefore research and develop a kind of grindability good, active high breeze grinding aid become this area in the urgent need to.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of breeze grinding aid, uses grinding aid of the present invention to improve breeze grindability, enhances the activity of breeze, promotes the utilization ratio of breeze.
For achieving the above object, the present invention adopts following technical scheme:
A kind of breeze grinding aid, be made up of the raw material of following weight percent:
Preferably, breeze grinding aid of the present invention, be made up of the raw material of following weight percent:
Above-mentioned tetrafluoroethylene and the particle diameter of dihydrate gypsum are preferably 1 ~ 5 μm.
The present invention also comprises the application of breeze grinding aid in grinding breeze described above.When being specially grinding breeze, described grinding aid incorporation is into ore grinding powder total amount 0.03 ~ 0.07%, can significantly improve the mill efficiency of breeze, reduces energy consumption, improves breeze active.
Preferably, during grinding breeze, described grinding aid incorporation is into ore grinding powder total amount 0.05%.
Beneficial effect of the present invention is:
The trolamine that the present invention adds and stearic acid sodium are tensio-active agent, play and reduce the capillary effect of mineral powder granular, thus reduce breeze surface energy, overcome the magnetism between breeze, reduce viscosity, reduce resistance, improve the mobility of breeze, thus raising grindability, also can increase substantially the specific surface area of breeze; Polyacrylamide and tetrafluoroethylene have lubrication, reduce grinding resistance, and improve wear resistance, wherein tetrafluoroethylene is the particle of water insoluble alcohol, and hardness is higher, can improve the intensity of breeze; Water glass and dihydrate gypsum can improve the intensity of breeze, and wherein water glass can also improve the intensity of breeze; Sodium hexametaphosphate 99 and trisodium phosphate are as dispersion agent, avoid breeze to assemble and affect grinding, wherein Sodium hexametaphosphate 99 is for the dispersion of the compositions such as aluminum oxide, titanium oxide, magnesium oxide, trisodium phosphate is for the dispersion of the composition such as silicon oxide, calcium oxide, and dispersion agent is with strong points, improves breeze mill efficiency, improve output, reduce power consumption, can also promote that each feed composition plays synergy, improve the adaptability of breeze grinding aid and breeze.Joined in breeze by breeze grinding aid of the present invention and carry out grinding, output increased more than 20%, energy consumption reduces by more than 15%, and specific surface area increases by 19 ~ 31m
2/ kg, 28d activity index rises to S85 level from S75 level, improves a rank, and 45 μm of screen over-sizes are reduction by 1.59 ~ 1.95%.
