Abstract

The invention discloses a preparation method of a stone powder exciting agent, and relates to the technical field of exciting agents. According to the key points of the technical scheme, the preparation method comprises the following steps: step 1, taking 86.4-96.6 parts by weight of stone powder as a mixture I, and mixing 2.86-3.22 parts by weight of sodium thiosulfate, 1.62-1.83 parts by weight of sodium hydrogen sulfite, 0.66-0.75 part by weight of sodium silicate, 0.37-0.41 part by weight of aluminum hydroxide and 0.22-0.28 part by weight of hollow glass beads to obtain a mixture II for later use; step 2, grinding the mixed material I in a grinding machine, and drying during grinding to obtain a ground material I of which the specific surface area is greater than or equal to 320m < 2 > / kg; the second mixture is put into a mixer and dried during stirring and mixing, and a first mixture is obtained; 3, the first grinding material and the first mixed material are guided into a friction combining machine according to the proportion and guided into a stirring and mixing machine located at the bottom of the friction combining machine to be stirred under the dual action of horizontal friction force and gravity, and the finished stone powder exciting agent is obtained. The cement compound has the effects of improving the activity of the cement compound and achieving the purpose of eliminating solid waste.

Description

technical field [0001] The invention relates to the technical field of activators, and more specifically relates to a method for preparing a stone powder activator. Background technique [0002] At present, the production and use of cement in my country has reached a peak period. The large amount of slag and other active cement mixed in the cement production process makes the supply of slag in short supply, and when the slag is stored for too long, the internal active components are prone to hydration reaction, which greatly reduces its activity, and at the same time, the slag is easy to grind. The coefficient is relatively high, which leads to a reduction in the output of cement mills per hour, an increase in power consumption for grinding, and an increase in the cost of cement enterprises year by year. Since the activity of cement comes from cement clinker, the cement mixture will reduce the neutralization activity, but because the cost of clinker is much higher than the ...
