Embodiment 1
[0032] A method for preparing heavy calcium carbonate for high-activation silicone rubber, which sequentially includes ore storage, cleaning, mineral processing, crushing and homogenization, grinding, grading, powder collection, quality inspection I, activation, cooling, and quality inspection II steps ;
[0033] The described ore storage steps are: storing the ore raw materials separately according to ore types and grades;
[0034] The cleaning steps are: cleaning the mud stuck on the surface of the ore with water;
[0035]The ore dressing step is: selecting the unqualified ore entrained in the ore; the unqualified ore is the ore with low whiteness, skin and other impurities;
[0036] The crushing and homogenizing step is as follows: crush the qualified ore into 18mm ore, and then send it into a 10,000-ton level homogenizing tank for homogenizing;
[0037] The grinding step is: sending the mineral material into the grinding equipment for grinding;
[0038] The grading step...
