screw conveyor factor


A decanting centrifuge consist of a conveyor screw inside a rotating bowl. Screw conveyor is an important part of a horizontal decanter centrifuge. Its role is to convery the solids settled against the wall of decanter bowl and push them across a drainage deck, or beach. Dewatering actually takes place on beach, with the decanted solids dischareged through a series of underfow ports.

The angle of inclination is a capacity limiting factor; the capacity falls-off sharply as the angle is increased. Other design factors that limit the screw conveyor capacity include the rotational speed, clearance between the blades and casing, screw pitch, overall dimensions of the unit and type of material conveyed.

Primary considerations for the selection of a screw conveyor are: 1. Type and condition of the bulk material to be conveyed including maximum particle size and specific bulk density 2. Capacity or feed rate of bulk material to be conveyed expressed in pounds per hour, tons per hour, or cubic feet per hour 3.

A standard Screw Conveyor inclined 15° upward will carry 75% of its rated horizontal capacity. At an inclination of 25°, a standard conveyor may only handle 50% of its horizontal capacity. These are estimated figures and will vary with the characteristic of the material being handled. Inclined Screw Conveyor capacities can be increased over ...

Screw conveyors, or auger conveyors, are industrial equipment used in transporting bulk quantities of granular solids (e.g., powder, grains, granules), semi-solids, liquids, and even non-flowing materials from one point to another. They uphold high operational efficiency by eliminating the need for the workers to manually move around loads.

The first step in sizing a screw conveyor is to determine the diameter. The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are ...
