disposers are pretty simple--and they all work on a similar
principle. They put a flat plate that has small, rotating, steel
mashers, and an inner disposer wall that has serrated
"teeth" to work to do the job of grinding your food
A motor inside the unit rotates the flat plate in the
food-grinding area. When you switch the unit on, the mashers are
forced to swing toward the outside of the spinning plate.
Note… Your disposer can jam if something solid or tough
gets lodged between the spinning plate and the inside wall of
the disposer. To find out how to clear a jam, see the
Troubleshooting section of our website.
There are two primary types of disposer:
you place food in the disposer and switch it on, the mashers
force the food against the serrated teeth of the inner wall and
shred it. The shredded food then falls through small holes
between the spinning plate and the inside walls, and is diverted
into the drainpipe.
The job of the rubber shield at the top of the disposer is to
keep fast-moving food particles from being ejected out of the
disposer. The stopper lets you plug the sink to hold water when
you're not using the disposer to grind food scraps.
feed disposers function exactly like continuous feed disposers,
except that, to switch them on, you place a special stopper in
the disposer opening and turn it. The stopper activates a switch
that turns on the disposer.
