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.
