78-1 magnetic heating stirrer is applicable to biological, physical and chemical, cosmetics, health products, food, reagents and other experimental fields. It is the experimental equipment for liquid mixing and stirring. The product concept design is novel, the manufacturing process is advanced, the low speed operation torque output is large, and the continuous use performance is good. The driving motor is a series excited micro motor with large power and compact structure, which is safe and reliable in operation; The operation state is controlled by a digital touch type stepless speed regulator, which is convenient for speed regulation; Digital display of running speed status and correct data collection; The output force amplifier adopts multi-stage non-metallic gears to transmit the force, with doubled torque, stable operation and low noise; Special rolling head for mixing bar, easy and flexible to unload. It is an ideal equipment for factories, scientific research institutions, colleges and universities, medical institutions and other scientific research, product development, quality control and production processes.

1. Determine the mixing purpose: whether it is necessary to realize heat transfer, absorption, extraction, dissolution, crystallization and other process purposes, such as liquid-liquid mixing, solid-liquid suspension, gas-liquid or liquid-liquid dispersion. The type of agitator is selected according to the process characteristics.

2. Calculation of mixing power: power required for mixing process
Reference formula: power=power criterion * liquid density * 3rd power of revolutions * 5th power of slurry diameter.
The calculation of power criterion is complex, which is related to tank diameter, slurry diameter, blade width, angle, number of layers, viscosity, number of baffles and baffle size.
