Welded wedge wire sieves

OPTIMA Slotted sieves, made of longitudinal profil wires and cross bars to a rigid sieve panel, are available in mild steel, in alloyed, wear-resistant and corrosion-proof steel grades and also in special qualities. The slots do not impede the material flow. The slotted openings widen downwards, thus effectively preventing pegging by marginal particles. OPTIMA slotted sieves are supplied ready to be build in, with or without reinforcement. OPTIMA slotted sieves are used for dewatering, deslurrying and classifying on screening machines, sieve bends, centrifuges and dewatering troughs, as...

OPTIMA plain sieve panels for screening machines. Front rail Plain sieve panels are ready-to-install sieves, with or without frame and/or reinforcement depending on: the load of the sieves, the distance between supports and the frame construction. The reinforcement is understood to be a frame which is firmly connected to the panel, as well as support rails etc. Vibration-proof fastening to the machines substructure is important to prevent premature damages and loss of production. Crossbar Side rail Support rail Plain sieve panels are fastened by slats and wedges along the sides of the...

Mild steel, chromeand chrome nickel steel grades For all profiles except 76 sbb, 150 sbb and Hs-profiles. Apart from the profile shown, longitudinal profiles can also be used as crossbars, or flat bars 10 x 2 to 60 x 3 mm. Other shapes of crossbars on request. Weight (kg/m²) Weight (kg/m²) Weight (kg/m²) Weight (kg/m²) MATERIAL QUALITIES Mild steel For sieves and reinforcements when the feed material is neither abrasive nor corrosive. For slot widths under 1 mm chrome and chrome nickel steel are to be preferred, for slot widths below 0.63 mm only these materials are used, to prevent the...

OPTIMA slotted sieves as plain panels, sieve bends, cylindrical sieves can be supplied with any technically possible reinforcement and/or frame. Many different profiles, slot widths, qualities and material combinations are available. OPTIMA sieve bend panels have a large open screen area allowing a high throughput. Sieve bends have the slots running across the flow direction. The feed causes unproportional wear of the profile edges on one side only, leading to an inscreasingly inaccurate cut size. This can be kept within limits by early turning of the sieve bend. This turning can be...

OPTIMA kiln floors for germinating and kiln-drying Ready for installation and reinforced as plain panels for rectangular and round kiln floors as well as for tipping and vertical kiln devices. Advantages: light weight, throughgoing slots, large open screen area, good ventilation, easy cleaning and maintenance. As a rule, we supply OPTIMA kiln floors with slot widths between 1.25 and 1.75 mm, preferable 1.5 mm. If the corrosion risk is low, they are made of mild steel, untreated or galvanised, in rare cases of chrome or chrome nickel steel grades. Picture 12 shows a modern, round OPTIMA kiln...
