Abstract
The invention discloses powder grinding addictive for coal-series hard kaoline. The main preparation process comprises the following steps of: adding various components including less than or equal to 1 percent of coal refuse (Fe2O3+TiO2), more than or equal to 2.5 of sodium water glass modulus, sodium hexametaphosphate, polyvinylalcohol, tributyl phosphate and gylcol ester into a ball grinder in turn according to the proportion, mixing, grinding, discharging and packaging. A non-metal grinding body must be adopted in the ball grinder. By using the powder grinding addictive, the powder grinding addictive enables the power consumption of a dry fine powder grinding work section of the coal-series hard kaoline to reduce by 6.5 to 8 percent and has the advantages of simple production, convenient use and low cost.
Description
Technical field
The present invention relates to a kind of powdery grinding aid that is used for coal-measure hard kaolin, refer in particular in coal-measure hard kaolin " the do wet method in conjunction with " production technique, a kind of powdery grinding aid that is exclusively used in dried regrind mill workshop section.
Background technology
In the present domestic coal-measure hard kaolin production process, the technological process of production of most employing the " do wet method in conjunction with ", dried regrind mill workshop section is one of them important unit production process; In total power consumption of coal-measure hard kaolin production process, the current consumption of dried regrind mill workshop section accounts for 35%～48% of total power consumption, and the approach that cuts down the consumption of energy has two, and the one, improve the performance of grinding machine; The 2nd, improve mill efficiency by adding grinding aid, present developing direction is a research and development advanced person grinding aid efficiently among both.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of powdery grinding aid that is used for the dried regrind mill of coal-measure hard kaolin workshop section, and this powdery grinding aid is by coal gangue (Fe
2O
3+ TiO
2)≤1%, sodium silicate modulus 〉=2.5, Sodium hexametaphosphate 99, polyvinyl alcohol, tributyl phosphate, glycol ester is compound formulated, and the addition when using is 0.1%～0.5% of grinding material.
The technical problem to be solved in the present invention is realized by following scheme: a kind of powdery grinding aid that is used for the dried regrind mill of coal-measure hard kaolin workshop section is characterized in that: the each component of forming the powdery grinding aid is by weight percentage: coal gangue (Fe
2O
3+ TiO
2)≤1% 75%～85%, sodium silicate modulus 〉=2.5 5%～10%, Sodium hexametaphosphate 99 2%～5%, polyvinyl alcohol 2%～3%, tributyl phosphate 2%～4%, glycol ester 1%～3%.Preparation process is as follows: quantitatively take by weighing each component in proportion, add in the ball mill and ground 1～3 hour, the grinding element in the ball mill must adopt non-metallic material, and ground and mixed evenly back discharging packing is the powdery grinding aid that is used for coal-measure hard kaolin.
Advantage of the present invention is: the use of powdery grinding aid makes the power consumption of the dried regrind mill of coal-measure hard kaolin workshop section reduce by 6.5%～8%; The powdery grinding aid also has simple, easy to use, the lower-cost advantage of production.
