Problems solved by technology

Therefore, a lot of tests have been done on these characteristics of the raw ore. No matter jaw crushing, impact crushing, gyratory crushing, cone crushing, roller crushing, hammer crushing or vertical shaft impact crushing, they can be crushed. Buton rock asphalt is relatively sticky and cannot pass through the sieve. Even if a pulse sieve high-pressure air sieve is used, the screen will be blocked over time. Therefore, traditional ordinary crushers cannot crush the raw ore of Buton rock asphalt to less than 3mm, let alone achieve Fineness below 1mm
[0006] Based on the above reasons, the application of Buton rock asphalt on road pavement is greatly limited

Embodiment 1

[0034] Such as figure 1 Shown, the method for utilizing boutonite asphalt to produce modified asphalt described in the present invention may further comprise the steps:

[0035] (1) Mix rock bituminous particles with a diameter of less than 1mm and thermogravimetric asphalt to obtain a mixed asphalt material with a diameter of less than 1mm. The amount of the thermogravimetric asphalt is limited to make the rock asphalt particles flow and not stick ;In the above process, the feeding and mixing of rock asphalt particles and thermogravity asphalt is realized through the feeding equipment and metering controller; 160°C, 165°C, 170°C, 175°C, 180°C, 185°C, 190°C or other temperatures within the range of 150°C to 190°C, as long as it is not higher than 190°C; rock asphalt particles with a diameter of less than 1mm may be produced It is obtained by processing the original ore of Butonite asphalt with foreign crushing equipment, and the specific source will not be repeated here.

Embodiment 2

[0039] Such as figure 2 and image 3 Shown, another kind of method of utilizing bouton rock asphalt to produce modified asphalt described in the present invention comprises the following steps:

[0040] (1) Crush the raw ore of Buton rock asphalt with an ordinary crusher to obtain rock asphalt particles with a diameter of less than 10mm. figure 2 The middle indicates that the rock asphalt raw ore is crushed by ordinary impact crusher;

[0041] (2) Quantitatively convey the rock asphalt particles to the thermal crusher 6 through the pulley 3, the screw lifting conveyor 4 and the electronic metering conveyor 5. figure 2 The thermogravimetric coke pitch in the metering control) is fed into the thermal crusher 6, the amount of thermogravimetric coke pitch is limited to the flow and non-bonding of the rock asphalt particles, and the thermal crusher 6 includes crushing, stirring and high-speed The shearing compound crushing method crushes the raw materials to obtain a mixed as...

Abstract

The invention discloses a method for producing modified asphalt by using Buton rock asphalt, comprising the following steps of: mixing rock asphalt particles with thermogravimetric pyrobitumen to obtain a mixed asphalt material with a diameter less than 1mm, wherein the amount of the thermogravimetric pyrobitumen is based on the fact that the rock asphalt particles can flow and are not caked as a limit; emulsifying and grinding the mixed asphalt material with a diameter less than 1mm to obtain a modified asphalt material with the fineness being not lower than 200 meshes; and carrying out conventional quality blending on the modified asphalt material to obtain the modified asphalt. The invention also discloses a hot method crusher which comprises a power device and a crushing device, wherein a shell of the crushing device is internally separated by a material separation cylinder; a stirring device is arranged at the middle segment of a main shaft in the material separation cylinder; a movable disc is arranged at the lower segment of the main shaft; and a static disc is arranged on the inner wall of the shell corresponding to the movable disc. According to the method and the device, the Buton rock asphalt with a melting point higher than 200 DEG C into the thermogravimetric pyrobitumen with modification temperature below 190 DEG C to obtain high-performance modified asphalt.

Description

technical field [0001] The invention relates to a production method and production equipment of modified asphalt, in particular to a method for producing modified asphalt by using Buton rock asphalt and a thermal crusher. Background technique [0002] Natural asphalt can be divided into soft asphalt and hard asphalt. Soft asphalt generally has a higher oil content. It is very valuable to use it as a comprehensive fuel and extract lubricating oil and fuel oil. The main components of hard asphalt are asphaltene, colloid and mineral asphalt matrix, and its use value on the road is very high. [0003] Natural Buton Rock Bitumen (also known as BRA) is produced in Buton Island, Sulawesi Province, Indonesia, in the South Pacific Ocean. The asphalt-like substance produced under the combined action of bacteria and bacteria is named after it is produced in Buton Island, Indonesia. Buton rock asphalt is a hard asphalt, so it is suitable for road paving. [0004] Buton rock asphalt u...
