Screening Considerations A Guide to Selection

The Step Screen has the highest hydraulic capacity of any fine screen due to its larger open surface area when compared to any other Fine Screen technology. Step Screens are available with either 3mm or 2mm thick movable and 3mm or 2mm fixed lamellas. For the 2mm option, the open surface area for a clean screen is 75% (3mm thick lamellas = 60%).

FUNDAMENTAL PRINCIPLES OF ROTARY METERS

The sizing of a rotary meter is simply the selection of the appropriate capacity meter for the given flow conditions. The actual flow rate should not exceed the rated capacity of the meter. Line pressure and line temperature should be considered. Applying the basic gas laws, the following formula may be used to size a rotary meter: Qs = Qd X Fp

Trommel screen Wikipedia

A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material

Powder Handling Chemical Processing Expert Forum: Re

The capacity of a rotary valve is the revolutions/minutes times the effective volume of the pockets. The volume of the pockets is the volume of each pocket times the number of pockets (usually 6 or 8). The effective volume is the effective fill of these pockets and is limited by the amount of aeration, speed or any restrictions to the flow path
