HOW DOES PRIMARY SCREENING WORK. Influent wastewater passes through the slots (slot sizes 0.25-2.50mm) of a mechanical screen, and the solid waste that exceeds the dimension of the slot remains on the external surface of the rotating slot tube from where it is scrapped and falls down into a sludge container.

screening media or steel plate on the top deck. They are heavy and have more powerful motors and drives than a regular circular motion screen. The primary screens have been designed for screening immediately after a primary crushing operation, allowing a maximum feed size of up to 400 mm. CS CLASSIFICATION SCREEN The CS classification screens ...

Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the ...

used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification.

Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • …

The roller device is obliquely mounted on the frame, and the motor is connected to the roller device through the coupling through the reducer and driven the roller unit. The material is separated from the top down through the screening cylinder, and the fine grade material passes through the screen hole of the cylindrical working surface.
