The working principle of the device is shown in Figure 3. Put the dried and dispersed asphalt mixture
(conventional asphalt mixture does not exceed 3.5Kg, rubber asphalt mixture does not exceed 1.5Kg)
into the corresponding washing drum. Then put the washing drum in the washing chamber.The
system controls the automatic injection of solvent, turns on the ultrasonic wave and the washing
drum rotates at the same time. The washed mixture liquid is centrifuged to separate the mineral
powder, and then separate the solvent and asphalt by distillation. The aggregates in the washing
drum and the centrifugally separated mineral powder can be dried inside the equipment.
Component
The equipment is mainly composed of washing device (including conventional asphalt and rubber
asphalt), centrifuge device, distillation system and drying device.

As shown in Figure 4, the washing chamber is made of stainless steel. In order to improve the
washing efficiency, the washing drum is driven by the motor to rotate in the washing chamber, and
is equipped with an ultrasonic washing device.
The washing chamber is equipped with a safety lock, and the equipment cannot be started when the
cover of the washing chamber is open.
Conventional asphalt washing drum
The conventional asphalt washing drum is composed of the drum main body and the Closing lid, as
shown in Figure 5. The washing drum is divided into three specifications, 63μm, 75μm and 90μm
respectively, and the appropriate size can be selected according to the actual use.

The rubber-asphalt mixture washing bucket, as shown in Figure 7, is made of stainless steel. There
are three specifications of 63μm, 75μm and 90μm, and the appropriate size can be selected
according to the actual use.
Figure 8 shows the agitator, which is driven by the stirring motor to rotate during washing to improve
washing efficiency.
Figure 9 shows the rubber collector. Since the density of the rubber is lower than that of the solvent,
during washing, the rubber particles are suspended above the solvent and separated by the rubber
collector.
Figure 10 shows the transfer handle, which is convenient for removing the washing drum from the
washing chamber.

Centrifuge device
The centrifuge device (shown in Figure 11) is mainly
composed of a centrifuge chamber, a centrifuge motor,
a centrifuge cup (shown in Figure 13), a movable cover
plate and a safety lock, as shown in Figure 12. It is
mainly used to separate the mineral powder from the
mixture liquid discharged from the washing drum. Due
to the high-speed rotation, the mineral powder remains
in the centrifuge cup, and the separated mixture liquid
is discharged into the mixture liquid tank.
The mixture liquid window can observe the color of the
liquid flowing out of the washing chamber, and the
washing time can be adjusted according to the color of the liquid.
Before the test, close the movable cover and compress
it with the hasp lock.
The device cannot be started with the safety lock open.

Distillation system
The distillation system (shown in Figure 14) mainly includes a solvent tank (left side), a mixture liquid
tank (right side), cooling pipe, and heater. There are two heating tubes in the mixture liquid tank for
heating, and the cooling pipe is located above the solvent tank.
The dispensing valve is used to take a sample of the asphalt mixture liquid directly from the
centrifuge.
Drying device
The drying part mainly includes condenser, vacuum pump and so on. During the drying process, the
solvent in the aggregate becomes steam due to heating, and the steam condenses into a liquid state
when passing through the condenser, and finally returns to the solvent tank.
Weighing device
The weighing device (shown in Figure 15) is located on the right side of the device and is used for
weighing during the test. The maximum weighing is 10Kg, and the accuracy is 0.1g. The weighing

device needs to be installed on a flat floor, away from vibration sources. There is a shelf under the
weighing device, and the accessories related to the test can be placed on the shelf, which is
convenient for use in the test.
IV. Operation
Preparation
①.The first test needs to add about 25L of highly stable new trichloroethylene solvent and inject it
into the solvent tank through the solvent injection port. The level of the solvent tank needs to be
checked before each test.
②.Add antifreeze to the chiller to the green mark of the liquid level.
③.Peel the sample into small pieces at room temperature and place it in an oven to dry. When the
temperature of the sample returns to lower than the boiling point of the solvent or at room
temperature, it can be loaded into the washing drum for washing. If the temperature of the
sample is controlled between 5°C and 10°C lower than the boiling point of the solvent, the
washing effect is better.

WARNING!
The maximum amount of mixture that can be added to the washing drum is no more
than 3.5Kg, and it is also determined by the mineral powder content in the mixture,
which cannot exceed the maximum mineral powder capacity of the centrifuge cup!
⑤.Place the washing drum with mixture in the washing chamber as shown in Figure 19. Slightly
turn the washing drum when putting it in. After the hexagonal hole at the bottom of the washing
drum is aligned with the rotating shaft, push the washing drum in, close the washing chamber
door, and lock the hasp lock.
