It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4ft by 8ft screen would be acceptable. The 1in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is and that screen capacity is x = tph/sq ft. The screen area needed under the jaw crusher is 38/ = sq ft.

ing (, plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (, plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill.

As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the ...
