With the rapid development of concrete production technology, people have higher and higher

requirements for the quality of concrete precast products. In particular, the color difference requirements 

and proportion of blocks should be consistent as far as possible. However, at present, the mainstream 

method of adding pigments is still that workers directly pour the weighed pigments into the blender, 

which has a great impact on the final product quality. At the same time, it also brings production safety 

problems.

Germany's Würschum pneumatic pigment adding equipment can be used for coloring all kinds of concrete 

products.

In production, a certain amount of pigment can be directly blown into the blender, which greatly maintains 

the consistency with the proportioning design.
