What does the scrubber do? And why do I need it?

The primary function of the dust and vapour scrubber is to reduce and minimize the dry solids feed inlet chute plugging. This is equally true for both cases where quicklime is being slaked and for cases where any dry powder is being prepared in a mix tank.

The scrubber will draw air through it, keeping the slaker or mix tank under slight negative pressure. Typically the air make up is drawn from as near the feed inlet chute as possible.

The key to successful scrubber operations is to correctly set up and adjust the airflow and water sprays as per the manual. Inspection of the scrubber is necessary from time to time, with that inspection interval varying depending on operations.
