Click on the hotspots for pop up information about that part of the image.

There are three hotspots to find, once you’ve read them all, move on!

Close it off

Mixer lids and other access points (covers, access doors, etc.) should be sealed and securely closed before starting the mixer to prevent the escape of dust.

Extraction

Extraction systems should be designed so as not to draw excessive amounts of raw materials from the mixer. When producing a dry mix, consider arrangements for a dust-free discharge of the mixed product.

Local exhaust points

The mixer charging point should be enclosed and provided with a local exhaust ventilation. Or, local exhaust ventilation can be supplied at points inside lid or rear of the mixer casing, in order to ensure a net influx of air through the mixer.

If you click or tap on the indicated hotspots on the image, more information will appear in a pop up box.
