MEP offer a wide range of Sieve Bends for use in many processes and industries. They are used in high capacity, wet screening applications to classify and dewater different forms of mineral. Our Static Sieve Bends are the result of sixty years experience in supplying complete processing plants and systems.
Our Static Sieve Bends are supplied complete with feed boxes, profile wedge wire or polyurethane decks, wear surfaces and flow diverters.
Our products are manufactured using high quality mild steel and can be supplied with, if required, galvanised support frames with a range of abrasion resistant linings to suit the application or customer preference.
Standard Sieve Bend units are available in 0.5m to 3.0m widths in 0.5m increments.
Overview
In general terms the Sieve Bend is used where there is a high proportion of water with the solids. It is therefore suitable, for example, as part of the process to remove contaminants from sand or to carry out a dewatering function in advance of a slurry centrifuge when dewatering coal fines.
The material that passes through the screen surface is approximately half the size of the slot aperture.
The shape of the particle, the volume of undersize and the amount of near size material in the feed determines the separation size as well as the volume that passes through the screen.
A Sieve Bend benefits over a flat sieve screen as the curved panels induce centrifugal forces that force the slurry onto the screen surface.
When dewatering and classifying particles of < 0.25 mm, a lower percentage of solids concentrate will increase the efficiency of the Sieve Bend.
The dewatering ability of the screen is determined by the percentage of open area. The wedge wire profiles used provide up to 50% more open area because of the narrower wire profiles.
Feed boxes are designed to reduce kinetic energy in the feed slurry before cascading onto the screens surface.
