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 ...

Screening is the separation of material into 2 - 6 different sized products. The material is separated by passing it through a vibrating screen box which has a number of different sized screens, or meshes, which the material falls through like a seive. The material falls onto attached conveyors which stock pile the end products.
Screening is the process of deciding on whether an EIA is required. This may be determined by size eg greater than a predetermined surface area of irrigated land that would be affected, more than a certain percentage or flow to be diverted or more than a certain capital expenditure.
The Manufacturing Process The preparation of sand consists of five basic processes natural decomposition, extraction, sorting, washing, and in some cases crushing. The first process, natural decomposition, usually takes millions of years. The other processes take considerably less time.
