A screw conveyor suits short, enclosed runs of heavy, wet, or abrasive material, while pneumatic conveying suits dry powder that must travel far, change elevation, or feed several points. This guide compares them on material, route, throughput, energy, wear, and dust, then shows how to choose in the right order.

Carrying, return, and impact idlers do three different jobs on a belt conveyor, chosen by position and duty. This guide covers what each type does, where it sits, and how to match the type, CEMA class, and spacing to the belt and material.

The flight is the helical blade that moves material along a screw conveyor, and its geometry is set by how the material behaves. This guide covers the flight and pitch types and how to match standard, cut, ribbon, and paddle flighting to sticky, abrasive, lumpy, or free-flowing material.

A belt conveyor moves bulk material on a continuous powered belt looped around pulleys. This guide covers what it is, how it works, its parts and types, and what engineers evaluate when specifying one for a given material, capacity, and path.

A conveyor runs on several pulleys, and each does a different job. The drive moves the belt, the tail turns it around, the snub adds traction, the bend changes direction, and the take-up holds tension. Here is what separates them and how the sizes are set.

A dust-tight seal stops solid particulate. A gas-tight seal holds a gas or pressure boundary. ANSI/FCI 70-2 puts numbers on the gap, and the seat you choose decides which one you get. Here is how to specify the class your duty needs instead of asking for tight shut-off.
