This was for a little vibrating screen plant. This is a good example of a choke feed hopper with plenty of hopper water.
The deck below is a screen deck we also fabricated.
On the subject of hoppers, you can have vibrating variants that in some cases, can assist in the liquefaction of introduced pay gravel.
Depending on the type of gravel you have, a vibrating hopper is sometime a good addition to your washplant. Be aware more moving parts and maintenance, not to mention cost!!
Most placer gravels are free flowing and feed out to a screening system just fine with a choke feed system. Millions of yards have been successfully treated with this type of hopper.
