The core of EB Drilled Screen Basket is Electron Beam (EB) drilling technology, a high-precision cold processing technique. The principle involves focusing a high-energy electron beam (energy up to 10-300kV) onto the metal material surface in a vacuum environment. Through electron-atom collisions, energy is instantaneously transferred, causing localized material to melt, evaporate, or even ionize, forming uniform micro-pores ranging from micron to millimeter scale. Compared with laser drilling, electron beam drilling offers smaller focal diameters (minimum 0.01mm) and heat-affected zones only 1/5-1/10 of laser drilling, completely avoiding material deformation or performance degradation.
EB Drilled Screen Basket performance is further enhanced: The smooth surface of EB-drilled stainless steel substrates reduces solid particle accumulation on basket surfaces, decreasing clogging probability by over 30%; Advanced surface treatment processes form wear-resistant protective layers on critical wear areas like basket edges and bottoms, extending service life 2+ times compared to standard baskets.
Its operational mechanism follows the "high-precision solid-liquid separation" principle: When filtration media passes through EB Drilled Screen Basket, uniform micro-pores formed by EB drilling (precision ±0.01mm) strictly retain solid particles larger than pore size while allowing liquids or qualified particles to pass through; Precise pore channel design ensures smooth media flow, reduces pressure differential losses, and guarantees long-term stable operation.
As a high-precision filtration component, EB Drilled Screen Basket parameters directly determine filtration performance. Hebei SLOT Filter implements full-process control of core parameters based on ISO 9001/SGS certified quality systems:
Pore Size & Precision: Pore size range covers 0.05mm-5mm with stable precision of ±0.01mm, far exceeding ordinary EB Perforated Screen Basket's ±0.1mm tolerance, meeting stringent requirements of precision filtration applications.
Open Area Ratio: Customizable 20%-40% open area ratio according to application needs. Through optimized pore pattern layout, open area ratio increases by 10% compared to industry average while maintaining mechanical strength.
Material Selection: Primarily uses 304/316L stainless steel (corresponding to Stainless Steel EB Drilled Screen Basket) with excellent acid-alkali corrosion resistance; Special scenarios can customize Hastelloy, titanium alloy, and other materials for highly corrosive media filtration.
Mechanical Strength: For Centrifuge EB Drilled Screen Basket, tensile strength ≥500MPa, dynamic balance precision reaches G2.5 grade, stably withstands 1000-5000rpm centrifugal speeds.
Surface Treatment: Passivation treatment enhances stainless steel corrosion resistance, polishing treatment reduces particle adhesion, special hardening processes improve wear resistance by 40%.

Compared with ordinary perforated baskets, EB Drilled Screen Basket improves filtration accuracy by over 40% and reduces clogging rate by 25%. EB drilling micro-pore precision is particularly suitable for fine particle retention, covering over 90% of industrial filtration applications.
Match Application Requirements: For centrifuge applications, prioritize Centrifuge EB Drilled Screen Basket and specify centrifugal speed requirements; For general industrial filtration, select Industrial EB Drilled Screen Basket.
Determine Filtration Precision: Select EB Drilled Screen Basket pore size based on D90 diameter of particles to be separated. For example: 0.2μm-1μm for pharmaceutical sterile filtration, 2mm-5mm for mining tailings processing.
Material Compatibility with Media: Choose 316L stainless steel for acidic media, Hastelloy for highly corrosive media, and consider special surface treatments for high-wear environments.
Verify Supplier Qualifications: Prioritize suppliers with ISO 9001/SGS certification and 15+ years experience (such as Hebei SLOT Filter) to ensure quality consistency.
Regular Maintenance: Perform ultrasonic cleaning every 2-4 weeks to remove residual particles from micro-pores and prevent clogging.
Customization Optimization: For special media or operating conditions for enhanced filtration efficiency.
Performance Monitoring: Install differential pressure sensors; when pressure differential increases by 20% or more, promptly inspect basket for clogging or wear.
A: Core differences lie in pore precision and uniformity. EB Drilled Screen Basket offers ±0.01mm pore precision with smooth pore walls, reducing clogging rate by 25%. Ordinary perforated baskets have ≥±0.1mm pore tolerance with irregular pore shapes that easily cause particle jamming.
