Aug 27 2014 · Purchasing an auger conveyor can be a tedious and overwhelming experience The nature of how product moves in an auger conveyor sliding through a tube with a screw or auger as opposed to just sitting on a belt requires the manufacturer to know a lot of detailed information about the product being conveyed and where it’s being conveyed information that most customers aren’t
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
A dual auger design can determine if the material will move left or right to accommodate your needs Screw conveyors are flexible and depending on their diameter can be curved to some extent A special heattreated tempered carbon or stainless steel spiral rotates with an ultrahighmolecularweight polyethylene UHMWPE foodgrade tube
Screw Conveyors JPM are leaders in the design manufacture and installation of screw conveyors and augers screw feeders and surge bins associated with mining rendering food processing pulp and paper and many other bulk materials handling sectors
Calculation of Conveyor Speed Conveyor Speed can be most conveniently calculated by use of the nomographs supplied on pages To use this nomograph – first locate the two known values screw diameter and required capacity in cu ft per hour then with a straight edge connect these two points
An auger conveyor or screw conveyor consists of a helicoid screw rotating within an enclosed tube or open Utube Fig 37Its invention is credited to Archimedes 287212 BC who used it to pump water from the holds of ships CEMA 2003With only one moving part in contact with grain lowcost augers are simple and find extensive use especially in intermittent use conveying systems
