Small colloid mill for manufacturing asphalt road surface and use method thereof

Abstract

The invention discloses a small colloid mill for manufacturing an asphalt road surface and relates to crushing, grinding or smashing. The small colloid mill is used for solving the problems that by means of an existing device, matrix asphalt and an auxiliary cannot be ground sufficiently, and consequently, a cross-linking reaction is not thorough. The small colloid mill comprises a motor shell, a vertical motor, a millstone structure, a feed hopper, a self-circulating pipe and a cooling water pipe connector. The vertical motor is arranged in the motor shell, the millstone structure is arranged above the motor shell, the feed hopper is arranged above the millstone structure, the upper side wall of the millstone structure is connected with the cooling water pipe connector, the lower side wall of the millstone structure is connected with the lower end of the self-circulating pipe, and the upper end of the self-circulating pipe extends to the feed hopper. The millstone structure comprises a millstone shell, a millstone stator, a millstone rotor and a first rotating shaft. By improving the millstone structure, grinding is sufficient, and the cross-linking reaction is thorough. The invention further discloses a use method of the small colloid mill for manufacturing the asphalt road surface.

Description

technical field [0001] The present invention relates to crushing, pulverizing or pulverizing, in particular, a small colloid mill for making asphalt pavement and its method of use. Background technique [0002] With the rapid development of our country's national economy, the task of transportation, especially road transportation, is becoming more and more heavy, and vigorously developing high-grade highways has become an important feature of the development of road transportation today. Among all the built roads, asphalt pavement is more and more widely used in pavement structure because of its good driving comfort, fast construction speed and convenient maintenance. However, with the development of the national economy and the improvement of people's living standards, the traffic volume has increased rapidly, and problems such as large-scale vehicles, serious overloading, and channelization of vehicles have emerged one after another. This makes the asphalt concrete paveme...

AI Technical Summary

Problems solved by technology

[0009] However, the above-mentioned technical scheme has the following disadvantages. The grinding of base asphalt and auxiliary agent is not sufficient, resulting in incomplete cross-linking reaction, and finally the modified asphalt produced cannot meet the anti-rutting ability of asphalt under heavy-duty traffic conditions.

The service life of asphalt pavement is low, the maintenance cost is high, the wear resistance of the paved pavement is poor, and the pavement is prone to peeling. After several years of use, the pavement will appear white, soft, piled up and cracked, especially in alpine regions The road surface is easy to tear, the service life is short, and the original state cannot be maintained under the condition of rapid temperature changes, and the durability is extremely poor, etc.
