AI Technical Summary
Existing heavy calcium carbonate is difficult to mix quickly in the initial stage of the stirred reactor, resulting in long stirring time and low production efficiency, which makes it difficult to meet the efficient production needs of modern industry.
A two-stage mixing component is adopted, including a first mixing hopper and a second mixing hopper. The first mixing hopper is provided with a bulk material protrusion and a material guide slope, which cooperates with the rotation of the stirring shaft to achieve preliminary mixing. The second mixing hopper throws out the material through centrifugal force to increase collision and fusion, thereby improving mixing uniformity.
It significantly improves the material mixing uniformity and stirring efficiency, shortens production time, and improves the efficiency of the production process and product quality.
