The Decanter Centrifuge UCA 501-00-02 decanter centrifuge is a continuously operating horizontal solid wall bowl centrifuge for maximum dewatering requirements of municipal and industrial waste water sludge. The frame is of open design with either gravity or pressure discharge of the clarified phase.
All parts coming into contact with the product are made of CrNiMo stainless steel. All gaskets coming into contact with the product are made of NBR (Perbunan).
The machine is coated in Seevenax RAL 6011 green, a synthetic resin paint.
The housing consists of a welded frame with feet, motor bracket, guards and catcher of stainless steel grade 1.4401 for the product discharge. Vibration dampers between housing and foundation frame prevent largely the transfer of vibrations and are included in the scope of supply.
Bowl and scroll
The decanter is equipped with a flat angle cone bowl with grooves in cylinder and cone. The solids discharge is equipped with exchangeable bushes made out of tempered cast iron for protection against wear and tear. The conveyor scroll is of single-thread design.
The decanter bowl is driven by a standard 3-phase AC motor designed for controlled torque starting in a star delta circuit. Power transmission is via V-belts. For the decanter type with standard gear drive the motor drives the bowl and scroll with only one gear.
Equipped with a 2-gear drive system the differential speed is adjusted automatically, which ensures constant solids drying in case of fluctuating feed concentration and product volumes. The differential speed is analogue controlled for the solids loading as soon as a preset threshold value is exceeded. The differential speed adjustment could be necessary to react to a change in torque depending on the control gradient.
