Compactor compresses powdered materials
precisely
The Alexanderwerk 'Power Pactor' roller compactor, being demonstrated at Total Exhibition by UK agent Orthos Engineering, will compress a wide variety of powdered materials into robust flakes
It combines flexibility of operation with very high consistency of product quality A special screw feeder with vacuum de-aeration eliminates the explosive venting of entrained air through the rollers and facilitates the processing of light, voluminous material

New large diameter automotive catalyst extruder
Orthos introduces a BMS-KEMA high-pressure extruder, the VENR 500, for the manufacture of large-size catalyst honeycomb units for use in Selective Catalytic Reduction (SCR) systems for diesel engines
This can then be used in flake form or broken down into granules for subsequent dust-free use.
A new vibratory hopper and micro batch processing attachments will also be shown.
Ideal for laboratory/pilot scale production from 5g to 30kg/hr, the Power Pactor is FDA/cGMP compliant.
Powdered products which lend themselves to this form of densification include potash and metallic ores, sugars, citric acid or other food additives, salts, oxides, talc, urea and activated carbon, as well as pharmaceuticals.
The unit's screw assembly is fed by the Combi Vent Feeder, which ensures that recycled fines from the flake-breaking section and the dust collection system are proportioned uniformly into the main feed stream.
This, combined with de-aeration, produces a flake of outstandingly consistent thickness and density.
The two rollers are vertically mounted and fed by the integrated, horizontal double-screw feeder, with the top roller free to move up and down.
They are equipped with four 7.5kW geared motors and scrapers to eliminate scaling on their surfaces.
Each 250mm diameter x 200mm long roller is machined from a solid piece of special rolling mill steel.
Roller speed is continuously variable between 10 and 22 rpm by a frequency inverter and roller pressure is variable up to a maximum of 600kN (30kN/cm of roller length).
The rollers are water-coolable.
All product contact surfaces are of 316Ti stainless steel or FDA-approved plastics.
Total installed power is approximately 50kVA and cooling water demand is about 300 litres/hr.
Typical capacity figures are 4.0tph for NaCl and 1.6tph for talc. Request a free brochure from Orthos (Engineering) ...
