depicted above in the computer generated illustration are very common
to the screening plant industry. There are several manufacturers
offering different variations of a vibrating or shaking screen deck,
mounted on a box shape with a hopper fitted on top.
use, a load of material to be screened is placed over the hopper, the
load is then dumped in the hopper and on to the screen deck, usually by
jogging the bucket to spread the material out minimizing momentary
fines, material that passes through the screen is collected in the box.
The overs, material that will not pass through the screen is dumped
along the long side of the box.
the load has been dumped, the loader goes to fetch another load,
repeating the process until the box is full. Once the box is full, it
must be emptied to proceed with the project.
capacity of the screen deck is variable with the size of the deck,
usually measured by length and width. This type of a screening machine
is considered by many to be the simplest and lowest cost of all
screening plant methodologies.
