Solids Heavy Design
The solids heavy design is used for abrasive bulk solids as well as corrosive bulk solids and/or higher temperature processes in compliance with the Machinery Directive without Annex 1(2.1). Food processing machinery. For high loads in potentially harsh operating conditions.
- Carbon steel or stainless steel versions, or equivalent casting materials
- Surface casting sandblasted on the outside Ra = approx. 12.5 µm, permissible casting defects according to quality class VC3 to DIN EN 1370
- Wear resistant and/or temperature resistant
- Very stable and robust constructions
- Dimensioning and design according to relevant standards and guidelines
- Wall thicknesses and welds according to strength requirements
- Interrupted weld seams are permissible
- Welds in principle according to EN ISO 5817 quality level C
- Pressure proof or pressure shock resistant components with the required verifications
- Support constructions where necessary with static calculations
- Carbon steel surfaces chemically descaled, primed and painted
- Optionally sandblasted, degree of purity SA 2.5 according to DIN EN ISO 8501-1
- For stainless steels: Weld seams pickled and passivated
