Working Principle of SENTEC 3D Printing Intensive Sand Mixer

Mixing Principle

The high-speed rotating agitator drives foundry sand, binders, and hardeners into intense convective mixing inside the mixing chamber.
The agitator geometry, dimensions, and rotational speed are precisely optimized to ensure uniform material distribution, providing stable molding performance for 3D printed sand molds.

Temperature Control Principle

Equipped with a hot air heating system and temperature sensors, the mixer continuously monitors sand temperature in real time.
The system intelligently adjusts hot air temperature and airflow to maintain constant sand temperature, ensuring reliable binder curing and optimal sand performance.
