Delivery scope & origin
Machinery assembly supplyEMKO project portfolio. Supplier at the time of delivery: EMKO HOLDING s.r.o.
The project in context
Supply of two screw feeder assemblies for polyethylene production. One assembly was intended for wet filter cake, while the other included a variable-frequency drive panel and flexible inlet and outlet connections. Distribution boxes, local control boxes and accessories completed the scope.
The project included technical definition of the screw feeders, coordination of mechanical and electrical parts and export supply of two separate assemblies.
The first screw assembly was intended for wet filter cake. Its design sheet specified a powder-and-hexane mixture, a process temperature of 60 °C and a design flow of 55.2 t/h.
The second assembly was designed for a mixture of powder, pellets and stabiliser, with a design-flow range of 10–55 t/h. These values describe the equipment design conditions.
The technical design specified AISI 304 / EN 1.4301 stainless steel, a U-trough made from 6 mm plate and ribbon screw flights welded to a central pipe. Bearings were outside the trough, with nitrogen-purged sealing.
Both assemblies specified 11 kW SEW EURODRIVE geared drives. The design included cleaning and inspection openings.
The February 2024 invoiced scope comprised both feeder assemblies and their distribution and local control boxes. The second assembly also included a variable-frequency-drive panel and flexible inlet and outlet connections.
The reference covers the coordinated supply of mechanical assemblies and electrical accessories for subsequent process installation.
Two feeder assemblies were supplied with the accessories covered by the commercial invoice.
