Conturbex Screen Scroll Centrifuge
The construction and working method of the Conturbex Screen/Scroll Centrifuge is shown in the cross sectional drawing. Drive unit, bearings, rotating parts in the liquids chamber and the solids discharge are clearly visible and easily accessible for maintenance. The drive is by vee-belts and the speed of the rotating parts is chosen to sult the process requirements. A cyclo gear unit ensures the necessary differential speed between worm and basket, even with a high friction between the two. An overload protection system prevents damage to the cyclo gear unit.
Gearbox and bearings have a pressurised lubrication system, with the exception of the H 200 which has a oil filled gearbox. Machine and drive motor are mounted on a base frame provided with rubber feet which can be bolted to the support construction.
Even our largest centrifuge can be installed without special foundations or balancing weights. The relative movement of the worm, ensures even distribution of the solids on the screen, thus preventing undue vibration. No potentially unbalancing solids remain in the worm when the machine is stopped.
Materials of Construction.
The contact parts are made from austenitic steel, special bronze, hastelloy, nickel, titanium or similar depending on the application. With abrasive materials, the vulnerable zones are protected by abrasion resistant materials.
