Performance of laboratory mixer and stirrer

Let’s take a step-by-step look at how the mixer works.

First of all, you must first turn on the device.

Then, before setting the device from the control panel, you can measure and place the necessary materials.

Step one:

Rotor blades that move or rotate at very high speeds apply very powerful suction.

Suction pulls liquids and solids from the bottom of the container upwards.

The mixture of liquids and solids moves to the center of the work.

second stage :

The centrifugal force directs the material to the working edge of the machine.

The machine grinds the material between the end of the rotor blade and the inner wall of the stator.

third level :

Intense hydraulic cutting is followed by high-speed material movement.

The material moves through the holes inside the stator.

After that, the materials circulate in the main body of the mixture.

Step 4:

At this stage, the material moves radially from the head to the mixing vessels at a very high speed.

As this process continues, your supply of fresh ingredients will continue.

This allows the work to absorb more material to maintain the mixing cycle.

Horizontal radial suction and discharge creates a circulating pattern that minimizes aeration.

Aeration is often the result of a disturbance in the fluid level.

From the edge of the mixer, you can now collect the mixture and continue the other steps.
