Description

This unit is for extraction of the constituents of an asphalt mixture using the non-flammable solventtrichloroethene.


Centrifuge

Steel casing with powder coating. Light-alloy spindle with maintenance-free ballbearings, speed 5500/11000 1/min, driven with a three-phase motor via flat belt. Thespindle is foreseen for centrifuge cups 120 mm dia., catalogue no. 20-0330 for up to 200 gof filler or 20-0335 for 200 up to 300 g of filler. In addition we recommend using cup insertpaper 20-0340.


Sieving /washing unit

Sieve vibrator with potentiometer at control box for setting sieving intensity. The solvent issupplied by a pump from the recovery unit to the spray nozzle in the sieve cover.


Recovery still

Two internal chambers, left one for distillation and right one serving as a clean solventreservoir. Distillation chamber heated with tube-type heating elements comprising the mainheater of 1500 W and two supplementary heaters each of 1000 W. Distillation capacity fortrichloroethylene and cooling water temperature of about 8°C with main heater approx. 10l/h, with supplementary heaters switched on add. approx. 35 l/h. At a solvent level of around2 cm above the heating elements, level switches start the elements automatically. Whenthe solvent level drops to about 5 mm above the elements, they are switched off.Additionally, two temperature limiters are fitted as a protection against excessive heating.This could occur in the event of malfunctioning of the level switches, or if the temperaturerises due to distillate consisting of almost pure bitumen. Should this be the case, then drainthe bitumen from the distillation chamber and reset the temperature limiter after the heatershave cooled. The distillation chamber can be cleaned by operation of a spray nozzlecontrolled by a pushbutton at the front of the recovery unit. For taking a solvent-/bitumensample during extraction, a drain valve is provided at the right front of the recovery unit.
