Problems solved by technology

[0004] However, the above method also has the following two disadvantages: on the one hand, the high-temperature carbonization of the bituminous ore particle surface will produce toxic gases, and a large amount of processing will pollute the environment, which is not environmentally friendly and does not conform to the current social development trend; on the other hand , a carbonization furnace that can carbonize asphalt ore particles, the cost is basically about 60 million yuan, the cost is very high, and it does not conform to the development trend of the enterprise

Embodiment 1

[0037] Mix 100 parts of natural bituminous ore with 3 parts of light calcium carbonate and crush it into asphalt ore particles with a fineness of 1 cm; then pass through the surface drying tunnel at a speed of 7 meters per minute, the drying temperature is 20 degrees, and the The time is 8 minutes; then it is crushed by a fine crusher until the particle size of all particles is less than 4.75 mm and the particle size is not greater than 1.18 mm accounting for not less than 80% of the total particles; metered packaging.

Embodiment 2

[0039] The natural asphalt ore is crushed into asphalt ore particles with a fineness of 2 cm by a coarse crusher; 100 parts of asphalt ore particles are mixed with 30 parts of heavy calcium carbonate, and then passed through the surface drying tunnel at a speed of 6 meters per minute, and dried The temperature is 30 degrees, and the drying time is 7 minutes; then the bituminous ore particles are crushed by a fine crusher, until the particle size of all particles is less than 4.75 mm and the particle size is not larger than 1.18 mm. The amount of particles is not less than 80% of the total particles; Measured packaging.

Embodiment 3

[0041] The natural bituminous ore is broken into bituminous ore particles with a fineness of 3 cm by a coarse crusher; then it passes through the surface drying tunnel at a speed of 10 meters per minute, the drying temperature is 40 degrees, and the drying time is 6 minutes; Parts of bituminous ore particles correspond to 5 parts of quartz sand powder, and then the bituminous ore particles are crushed by a fine crusher until the particle size of all particles is less than 4.75 mm and the particle size is not greater than 1.18 mm. The amount of the total particles is not less than 80%; metered package.

Abstract

The invention discloses a process for processing natural asphalt by virtue of an aid method. The process comprises the following steps: (1) crushing natural asphalite into asphalite particles with the fineness of 1cm-5cm; (2) enabling the asphalite particles obtained in the step (1) to pass a surface drying path at the speed of 5m/minute-10m/minute, wherein the drying temperature is 0-100 DEG C, and the drying time is 1-10 minutes; (3) crushing the asphalite particles processed in the step (2) by a fine crusher until the particle sizes of all particles are smaller than 4.75mm and the quantity of particles with the particle sizes smaller than or equal to 1.18mm is less than 80% of the total quantity of the particles; (4) carrying out measurement packing. The process further comprises the following step before or after the step (1), step (2) or the step (3) or before the step (4): mixing the natural asphalite or the asphalite particles with a separation agent. The invention further discloses a production line for processing natural asphalt by virtue of the aid method. According to the process and the production line, toxic gas is not produced, and high-cost carbonization furnace equipment is not used, so that the energy and the spending are saved.

Description

technical field [0001] The invention relates to the technical field of ore processing, in particular to an additive method natural asphalt processing technology and a production line thereof. Background technique [0002] Natural asphalt ore is a non-metallic mineral, including naturally produced solid and semi-solid asphalt, soft asphalt, stone asphalt, carbonaceous asphalt, carbon asphalt, high nitrogen asphalt and asphaltene-containing rocks. One of the most important uses at present is to mix it with liquid asphalt and lay it on the road surface to form asphalt pavement. Due to the viscous asphalt, the pulverized bituminous ore will condense into blocks after being placed for a long time, and it still needs to be re-crushed for subsequent use, which is very inconvenient. [0003] In the prior art, in view of the above phenomenon, the most important solution is to pass the pulverized bituminous ore through a high-temperature carbonization furnace, so that a carbonized fi...
