Apron Feeders - Osborn

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 and is ideal for withdrawing material from under a stockpile or from under a Primary Crusher. Apron Feeders are of rugged, heavy duty construction and designed to handle feed sizes of up to 1500mm and where no fines removal is ...

High Torque, Low Speed Wins - MRO MagazineMRO Magazine

High shear force will increase the starting torque of apron feeders a minimum of 100% — and 50% to 75% for belt feeders. Coarse ore feeders withdrawing materials of greater than 305 mm in size may require additional starting torque (figure 5). In addition to starting torque, allowance should be made for filling pressure (figure 6).

SHEAR STRESS - American Excelsior Company

Shear stress is the force applied by flowing liquid to its boundary. In this case, the liquid is storm water and the boundary is the channel surface. Shear stress is also occasionally referred to as the “tractive force.” Put simply, shear stress describes the force of water that is trying to drag the channel surface downstream with it. Shear stress is calculated based on the principle of ...
