BS 4409-3 standard is a part of the BS 4409 series that discusses the method for calculating drive power for screw conveyors. Screw conveyors are used for conveying bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance.
BS 4409-3 establishes a method for the calculation of the drive power of screw conveyors. BS 4409-3 only applies to a screw conveyor, used in a horizontal or inclined position (up to approximately 20°), for a regular, controlled and continual supply of the bulk materials.
BS 4409-3 on screw conveyors applies to:
Screw conveyors are used for conveying bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix.
BS 4409-3 provides you with the method for the calculation of the drive power of screw conveyors. It also provides the calculation of the capacity of screw conveyors in which the nominal capacity is considered the capacity per hour of the maximum volume that is reached by a screw conveyor. This helps you in manufacturing the screw conveyors in a standardized manner.
Overall, BS 4409-3 helps you to build consumer trust and confidence in the product.
