2. sonicated：Sound wave water process is mainly the colloidal ion group destroyed in water, make colloid group in water with it is net
Agent settles.
3. filtering：The suspended matter in water removal and part colloid are removed by gravitational settling, the turbidity of water is reduced, then passes through height
Activated adoption object is filtered absorption to supernatant liquor, removes residual molecule.
4. the thickening of water is handled：Thickener is added in 3. water that step obtains, stirs 10min, increases the viscosity of water, with
Sound wave dispersion is carried out afterwards, realizes the homogenization of water quality, it is required when obtaining grinding aid compounding to use water.
Processing parameter and correlated quality percentage are as follows described in each step：
(1) cleanser：3%~10% (percentage of water quality)；

The alcamines is one or both of triethanolamine, triisopropanolamine, diethanol amine, diisopropanolamine (DIPA).
The industrial waste is one or both of crude glycerine, resinol, glyceride, sugarcane waste residue.
The present invention provides a kind of technique improving grinding aid homogeneity, has the following advantages that：
(1) present invention avoids water-borne glue body and ion component pair by the processing to water in grinding aid compound process
The absorption and complexing of grinding aid active ingredient improve the active ingredient of grinding aid, improve grinding aid performance, reduce grinding energy.
(2) technique makes the viscosity of water increase, and is effectively improved the settlement issues of grinding aid, gained grinding aid stable homogeneous.
