The screening a Static Grizzly separator does is sort and classify the rock according to size. The first stage is SCALPING. This is the practice of removing any material that may slow production. It may be rock that is too big for the equipment to effectively handle, or fine material that is taking up valuable space and will consume precious energy if there is further handling. The name of the ...

Wheat Cleaning Basics

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 ...
