Product features
Wastewater treatment plants and industrial applications like food or paper mills, require mechanical treatment to process wastewaters as a first step to remove the floating, settling and suspended materials as much as possible. The aim is to reliable and efficiently achieve the maximum separation under the prevailing hydraulic conditions.
The YMX Rotary Drum Screens are based on a unique system that allows the combination of screening, washing, transport, compaction and dewatering in a single unit.
Depending on the screen bar spacing (0.5 - 6 mm) or perforation/slot sizes (1 - 6 mm) and screen size (screen basket diameter of up to 3,000 mm), the throughput can be individually adjusted to the specific site requirements.
The YMX Rotary Drum Screen is completely made of stainless steel 304 or 316, and acid treated in a pickling bath.
With an inclination of 35°， the YMX Rotary Drum Screen units are either installed directly into the channels. The wastewater flows into the open end of the inclined screen basket. The floating and suspended materials are retained by the screen basket. Blinding of the screen surface generates an additional filtering effect so that solids smaller than the basket opening can be retained in the basket, and thus rotate with the upstrreat water level. The rotating screen drum lifts the screenings and drops them into the centrally arranged trough. Screenings removal from the drum is supported by a scraper brush and a spray nozzle bar. A screw conveyor in the trough rotates with the drum and transports the screenings through a closed and inclined pipe. The conveying screw transports, dewaters and compacts the screenings, without any odour nuisance, and discharges them into the customer‘s container or a subsequent conveying unit.

Benefits of the YMX Rotary Drum Screen
■ No by-passing
The entire flow enters the screen drum through its open front end and can only leave the drum through its screen area. This prevents plant overflow and guarantees that the screenings are always retained within the screen drum.
■ Several functions combined in one system
Perform the functions of screenings removal, transport, washing, dewatering and compaction in a single space saving unit.
■ Retrofitting
The design of the RO Screens allows for later modification so that the systems can be adapted to changing requirements. The heating and/or integrated screenings washing can be retrofitted. The bar spacing can also be reduced to meet more stringent requirements.
■ Low maintenance
No lubrication. Regular checking and visual inspection are sufficient.
