Brass Frame Sieves

Brass Frame Sieves

Complete range of full depth testing sieves 200, 250, 300, 315 and 450 mm dia.
All frames, except the 450 mm dia. -made of sheet steel- and wire cloth sieves are manufactured from stainless steel.
Perforated plates are made from tinned steel.
Sieves having the same nominal dia. are designed to nest one in each other.
Using 200 mm sieves (8”) is possible to test up to 1000 g of aggregates and 3000 g with 300 mm (12”) dia.
The sieves specifications are clearly marked on the label comprising the serial number and other information for the identification and traceability of the product.
Important note :
The EN standards specify that: “Sieves with aperture size of 4 mm and above shall be perforated plate square hole test sieves.
Below that size they shall be woven wire test sieves”.
