Multotec manufactures a complete range of polyurethane and wedge wire sieve bends and housings for classification and separation applications in the gold, diamonds, platinum, coal and iron ore processing industries.
Engineered to achieve an even spread of feed and adjustable flow control, Multotec sieve bends are used in:
Our sieve bends are manufactured in standard arc lengths of 800, 1 200 and 1 600 mm. We also manufacture non-standard sieve bends, with customised arc angles, radii and developed lengths, for existing installations.
Designed for excellent abrasion and impact resistance, with modular screen panels enabling fast and easy maintenance, Multotec sieve bends help improve your process efficiency and overall plant performance.
Your local Multotec branch will assist you with optimising your sieve bend installation.
Maintain a constant cut point over a long service life. Self-supporting internal frame provides excellent strength and durability.
Wedge wire sieve bends provide maximum open area and drainage, with a sharp cutting action. Wide range of profiles available.
Made from steel or HDPE, Multotec sieve bend housings are a high-quality frame for your polyurethane or wedge wire screen.
Reversible sieve bend housings can be equipped with pneumatic or hydraulic tilting systems as required.
The sieve bend (or DSM screen) is an important and effective solution in size classification and dewatering fine particle slurries in heavy minerals processing applications. Sieve bends do not require power to operate (unless a tilting system is integrated), and are a low-cost, quiet and efficient part of your screening process. The curved screen of the sieve bend provides greater capacity than flat wedge screens due to increased gravitational forces on material flowing against the curve, offering higher material throughputs.
Slurries are delivered to the feed box above the sieve bend and overflow onto the screen, which separates water and smaller particles from larger particles, which continue down the screen surface until most of the liquid is removed.
Multotec will match the required cut point, feed rate and solids concentration of your application with the optimum polyurethane or wedge wire sieve bend screen for maximum separation efficiency.
Our sieve bends are manufactured in three standard arc lengths. Customised sieve bend sizes, with 60 arcs, various radii and developed lengths, can also be supplied as your application requires.
800 mm Arc Length
1 200 mm Arc Length
1 600 mm Arc Length
Multotec manufactures sieve bend screens in both polyurethane and wedge wire to provide the most efficient solution for your plant.
Wedge wire is the optimum dewatering screen, with a sharp cutting action and maximum open area and drainage. Multotec supplies a wide range of profile wire sieve bends, manufactured with abrasion resistant 430 stainless steel and corrosion resistant 304 stainless steel.
Polyurethane screens are a cost-effective screening solution that maintains a constant cut point over a long service life. The continuous slot modules are designed to replicate the benefits of wedge wire. Deflector strips helps improve wear life on the screen panel, which requires less frequent turning for greater uptime.
