Process for manufacturing panels for floor and wall coverings

Process for the production of panels for floor or wall coverings comprising the steps of (i) mixing and homogenising raw materials, thereby obtaining a dryblend, (ii) extruding said dryblend, thereby obtaining one or more thermoplastic layers, (iii) laminating the afore-mentioned thermoplastic layers, thereby obtaining a panel for floor or wall coverings, whereby said raw materials and/or said dryblend are predominantly transported vertically downwards during the weighing, mixing and/or homogenising of said raw materials and during the feeding of said dryblend to extruders via feeding units, wherein said dryblend after homogenisation, is stored in an insulated buffer tank.
