Component Specifications

Definition
A structural component integrated into the main hopper of industrial machinery, designed to provide safe and convenient access for inspection, cleaning, maintenance, and emergency interventions. It typically features a sealed closure mechanism to prevent material leakage and maintain operational integrity during normal production cycles.
Working Principle
The access hatch operates on a hinged or removable closure principle, allowing it to be securely sealed during operation to contain materials and maintain pressure/vacuum conditions, then opened manually or with tools to permit entry for maintenance tasks. Sealing is achieved through gaskets, latches, or bolts that ensure a tight fit against the hopper structure.
Materials
Stainless steel (AISI 304 or 316 for corrosion resistance), carbon steel with protective coating, or aluminum alloy, depending on application requirements. Gaskets made from food-grade silicone, EPDM, or nitrile rubber for sealing.
Technical Parameters
  • Diameter 300-600 mm
  • Seal Type Gasket or O-ring
  • Thickness 3-6 mm
  • Pressure Rating Up to 0.5 bar
  • Opening Mechanism Hinged with latch or bolted
  • Temperature Range -20°C to 150°C
Standards
ISO 14122-3, DIN 2501
