Arc-sieves
Arc-sieves are used in the processes of filtration, dehydration, separation, slag-disposal. The productivity of one sieve depends upon the empty space and the type of profile wire. Approximate productivity of a sieve with the slot of 1 mm is 75-110m.
The usage of arc-sieves means the separation of hard substance from liquid on the slotting arc. Suspension is moved on all width of a sieve, liquid goes through the slot and the rest moves to the foundation of a sieve.
Thanks for the profile wire of triangle form and with wedge-shaped slit, self-purifying of a sieve is possible; it executes their blocking with the hard material.
Herewith it is very easy to change the sheet of a sieve on the condition of changing of parameters of the process and deterioration.
Arc-sieves are also used at the plants of food, pulp and paper and chemical industry, in filtration and recycling of water, in sewage disposal.
Also it is possible the production of flat (arc, cylindrical) sieves with the profile wire welded at the angle of regarding to the rigidity ribs. These sieves are used in the settling tanks with pneumatic movement of material and in the pulp and paper industry. During the work of such sieve carrying capacity depends upon the size of slot, and separation level depends upon the size of corner. The maximum angle of inclination is 12 degree.
