EM79 - ROTARY DRUM SCREEN
| Utilizzo | Screening of civil and industrial waste water. |
| Characteristics | The machine consists of a rotary drum. |
| Operation | The coarse solids are retained and remain outside the rotary drum. Then this material is removed by a cleaning scraper and the drum is washed by a washing system located inside the drum. |
| Materials | Compact machine: stainless steel. |
| Installation | Out of the channel. |
| Diametro del tamburo | 628 or 920 mm |
| Lunghezza del tamburo | From 500 to 3000 mm |
| Degree of filtration | From 0,25 to 3 mm. |
| Disadvantages | Cleaning brush. |
OPERATION DESCRIPTION
The machine operation is controlled by a Pause-ON timer.
If the water level in the tank of the water to be treated should increase and exceed a pre-set threshold, a level measurer can start the machine, even during the pause phase.
The water to be treated goes to the feed tank and is distributed all over the drum surface.
The machine is operated by a geared motor which controls its rotation.
The filtration process occurs from outside to inside the drum, so the filtered water comes out from inside the drum and keeps it continuously clean.
The solid material which remains outside the drum is scraped by a cleaning scraper which can be helped by a motorized brush which can be provided as an optional accessory.
The feeding is made by gravity or by means of a pump.
