Micro-perforation for nominal sized screen holes

Special Perforation Sheet

Micro-perforation technique is a logical enhancement of mechanical perforation method and is utilized when the nominal sized screen holes are needed. This makes it feasible to create Micro-perforation with hole diameters about 0.3mm for the extraction of fruit and vegetable juice or 0.1mm for fiber reclamation from process water.

The jet drilled screens are produced from stainless steel, carbon steel and special alloys. They have millions of small conical holes or slots. The smooth surfaces and conical open areas confirm the excellent material flow and large efficiency in the filtration process.

Applications of micro-perforation sheets

Centrifuges in the sugar, food and chemical industries, preparation technique, screening of starch, fruit juice and other food industries, for producing chemical sludge and running waste water, high functionality screens for plastic recycling, paper and cellulose units, screens for color and pigment preparation, process filters and screens for catalyzers, ion exchangers, resin traps and more.
