Pulp stirrer

The pulp stirrer drives the blades to rotate through an electric motor, ensuring the uniform dispersion of pulp fibers in water. It is used in laboratories to simulate the papermaking process and to measure pulp concentration and fiber distribution. It is commonly employed in papermaking process optimization and paper quality testing.
Selection
When selecting, consider matching the slurry characteristics with the rotational speed range, using stainless steel material to suit corrosive environments, and determining the stirring rod length based on container dimensions. The motor power must meet viscosity requirements, digital display facilitates data recording, and splash-proof design ensures clean operation.
