Table feeder is a circular plate or disk-mounted off-center and sealed against the bottom of the feed hopper. As the motorized table rotates, a groove in it fills the material from the hopper above and a knife or plugs scrapes the material from the table to the intake of the dryer. Flow can be controlled by changing the height of an adjustable feed collar or by regulating the variable speed drive of the table. Some of the advantages of table feeders is they can be used for materials that require wide hopper openings to eliminate arching, for sticky granular materials and for abrasive materials, the table feeders work well with materials that are highly cohesive or have very high shear factors and also it has low spillage problems.
