Wedge Wire Sieve Bend Dewatering Screens

Structure and Features:

    This series arc vibrating screen is a kind of grading equipment for fine material. It is mainly composed of arc sieving frame, stainless steel slot screen plate, vibration motor and distributing device. This machine has simple structure and easy installation. Also it has a good adaptability for fine mine sieving and is easily through sieve plate.ecialized in producing and distributing wedge wire screen,, sieve bend screen,sieve plate screen,water strainer&nozzle,screen nozzles,centrifuge screens and baskets,header-lateral etc.

Sieve Bend Screens

Sieve Bend Screens have another name as DSM sreens.Sieve bends are manufactured to suit a wide range of industries such as Sugar, Coal Mining & Quarrying, Mineral Processing, Cement, and Industrial & Urban Effluent Treatment etc. Widely used for fiber removal in Starch industry.

A sieve bend consists of a concave curved profile wire screen mounted in a frame with the screen openings perpendicular to the flow. A curved screen has greater capacity than a flat screen due to forces exerted as material flows against the curved surface.

As slurry flows down the screen each wedge wire’s sharp leading edge slices away a thin layer of water and small-particle solids. Larger particles continue down the screen surface, with much of the liquid removed. Separation size is considerably smaller than screen openings, usually about one half the opening size.

Sieve Bend Features:
Energy Efficient – operates with no moving parts and with no energy input.
Space Efficient – treats up to 122 litres per second per square metre of floor space.
Quiet Operation – no moving parts means no mechanical or electrical vibrations.
Accurate Sizing – can be used for sizing solid particles down to 20 micros.
Low Maintenance – the profile wire screen resists clogging by near-size particles, and the all-stainless steel construction ensures a long, corrosion-free installation.
Easy Screen Replacement – a typical screen can be replaced in 10 minutes with no tools.
Flexible Design – we can supply units with any features you may require.

Vibrating sieve screen plate Welded wedge wire screen

Vibrating sieve screen plate Welded wedge wire screen is manufactured by flat welded screen in panel or cylinder type.
Flat welded wedge wire panels offer a perfectly flat and smooth surface with rectangular openings. Flat Wedge Wire Screen Panels can be constructed using rectangular support rods or round support rods. Flat Wedge Wire Screen Panels can be designed to maximize the open area, strength and wear life to suit any application. Welded Wedge Wire Screens are made from V shaped profile wire, with an unique welding process, offering great strength, precision, long service life and a wide range of applications in the field of process, engineering such as sugar juice filtration, waste water treatment, crude oil and natural gas production and vessel internals solving problems of solid / liquid and solid / gas separation, filtration of oils, greases, paints, food products, water, fuels, liquid cooling agents, chemicals etc.

This kind of wedge wire can replace conventional media like wire mesh cloth, perforated plate and other metal sifting materials as components for rotary screen,well screen and etc.

Pressure screening in pulp and paper production

Pressure screening is the key process in pulp and paper production and is used to enhance the quality of a wide range of pulp and paper products. While theusual goal of screening is to remove oversize contaminants from the pulp with minimal fiber loss and acceptable cost, screening is finding increased use for fiber fractionation which means that the pulp can be split into fiber classes,

which differ in their average properties. For these reasons, pressure screen are an increasingly important unit operation in pulping, recycling and papermaking. In approach flow applications, pressure screening is the final stock cleaning stage before the headbox, and the machine is called headbox screen or machine screen. It is used to protect the headbox and paper machine from foreign material, to remove debris and dirt, to deflocculate the stock and to improve formation.

Johnson Stainless Steel V Wire Water Well Screen

1. Production process continuity: V-shaped profile wires creating slots which enlarge inwardly and therefore avoid clogging and minimize downtime.
2. Low maintenance costs: Separation at the screen surface which can easily cleaned by scraping or back washing.
3. Maximum process output: Precise and continuous slot openings resulting in accurate separation without loss off media.
4. Low operational costs: Large open area with an effective flow, high yield and a low pressure drop .
5. Long live: Welded at each intersection creating a strong and durable screen.
6. Reduced installation costs: supporting constructions eliminating costly support media and enabling a maximum flexibility in the design of components.
7. Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.
