Is it effective to grind the paint raw materials together?

Coating raw materials include kaolin, limestone, calcite, talc, gypsum, etc. Some putty powder factories directly purchase these finished powders, and then mix the materials evenly through a dry powder mixer according to the proportion, and then they can be made into coatings for use.
There are also many paint processing factories. In order to save costs and have abundant raw material resources, they often use Raymond mill for powder processing, grinding talc, gypsum, etc. into powder, and then discharging the materials. Use a screw conveyor to transport the powder to the mixer and mix it with other powders. At this time, the powder can be ground separately or mixed and ground together.
So is the effect of grinding the paint raw materials together? The talc, gypsum, limestone, etc. are directly put into the main machine for grinding according to a certain proportion according to the weight. There is no need to worry about whether the material proportion can meet the standard. What needs to be considered is, After these raw materials are ground, they have different densities and different weights. After passing through the air separation analysis machine, whether they enter the powder collector are uniform. If they are not uniform, you need to use a dry powder mixer to mix the discharged materials evenly before packaging. .
