This issue is crucial! The working principle of the roller extrusion granulator directly determines the core quality indicators such as the forming effect and uniformity of the particles, and the core influence is concentrated on the physical properties and consistency of the particles.

Core impact dimension

Squeezing force affects particle strength: the greater the squeezing force generated by the rolling mill, the higher the degree of densification of the material in the mold hole, the stronger the compressive strength of the particles, and the less likely they are to break; If the pressure is insufficient, the particles will become loose and prone to pulverization.

The speed of the rolling mill affects the uniformity of particles: too fast a speed can cause uneven material feeding, and some materials may detach from the rolling mill before being fully squeezed, resulting in large differences in particle size; If the speed is too slow, the production efficiency will be low, and the particles may deform due to excessive squeezing.

The design of the mold hole affects the particle morphology: the shape of the mold hole (circular, square, etc.) determines the particle shape, and the size directly controls the particle size; The smoothness of the inner wall of the mold hole can affect the demolding effect of the material, while roughness may lead to irregular and adhesive particle surfaces.

The uniformity of material force affects the overall quality: the synchronization of the relative rotation of the two rollers is crucial. If the speed is not consistent or the gap between the rollers is uneven, it will lead to an imbalance of material force, resulting in some particles being compact and some being loose, and poor overall quality stability.
