Apron Feeders – MEKA
MEKA Apron Feeders provide reliable means of controlling the feed rate to prevent surge loads to the Primary Crusher or other plant equipment. An Apron Feeder is run at very low speeds and at a controlled feed rate as it absorbs the impact loads of the material falling from a dump truck or a front-end loader. Apron Feeders are of rugged, heavy ...

Feeding the facts: Apron feeder basics
Normally, the optimal speed an apron feeder is 0.05 – 0.40 m/second (10–80 fpm). If the ores are non-abrasive, the speed can increase to above 0.30 m/second because there will be less wear. Higher speeds would hurt an operation. If your speed is too high, you run the risk of accelerated wear of components. Energy efficiency decreases due to ...
Apron feeders: the material handling workhorses
In simple terms, an apron feeder (also known as a pan feeder) is a mechanical type of feeder used in material handing operations to transfer (feed) material to other equipment or extract material (ore/rock) from storage stockpiles, bins or hoppers at a controlled rate of speed. These feeders can be used in a variety of applications in …
