Jaw Crushers: These are the oldest type of and most commonly used crushers in use and have changed little from the original 14 design. In Jaw Crusher the feed is compressed between a stationary and a movable surface.
Impact Crusher: The Impactor or Impact Breaker or double impeller breaker crusher uses the energy contained in falling stone, plus the power imparted by the massive impellers.
Screening is a process of separating into groups of different products of various sizes. Each group consists of products of approximately same size. Screening is generally classified into two types.
Sand and gravel often can be washed during the screening process but if the material carries undesirable matter a scrubber washer should preceed the screening process. When the stone from the crushing plant is coated with clay or other sticky substances they are put through rotary scrubber to scour the gravel before it goes to the screen. Material that contain smaller amount of clay and silt may be cleaned satisfactorily by a log washer. Washing is very rarely employed in Indian crushers, but it is common in developed countries.
