Belt Feeders – MEKA
In belt feeders, the rotation speed of the belt is adjusted by means of a power and reducer connection, and the desired feed capacity can be ensured by adjusting the speed. Most of the time, the motion system of the belt feeder is connected to the belt scale on the belt conveyor to which the material is conveyed after the feeder.Web

Apron Feeders
The apron feeder consists of a series of overlapping pans or plates which form a continuous chain like a conveyor belt. They are generally installed on a slight decline and driven to throw material in the downward direction. Widths of feeders range from one to 15 ft and lengths vary from one (for the largest) to five times their width.Web
