Embodiment Construction

[0007] A high-shear colloid mill, which includes a colloid mill housing 1 and a rotor 2, the rotor 2 is connected to the colloid mill housing 1, and the colloid mill housing 1 is provided with a heat-conducting oil chamber a, an asphalt medium chamber b, Water medium cavity c and lubricating medium cavity d. The four cavities are mutually independent in the colloid mill housing 1 and are mutually sealed.

[0008] The asphalt enters the colloid mill asphalt medium cavity b from the suction port of the shell 1, and the medium is ground in the colloid mill asphalt medium cavity b hundreds of thousands of times under the high-speed rotation of the rotor 2. In the process from the suction port to the outlet, the grinding area of ​​each stage is constantly changing due to the radial depth, so that the direction and instantaneous speed of the medium are constantly changing. When being sheared by the cutter teeth, the intense friction, extrusion and kneading between the molecules make...

Abstract

The invention relates to a high shear colloid mill, which comprises a colloid mill shell (1) and a rotor (2), and is characterized in that: the rotor (2) is connected with the colloid mill shell (1); and a heat conducting oil cavity (a), an asphalt medium cavity (b), a water medium cavity (c) and a lubricating medium cavity (d) are formed in the colloid mill shell (1), and are independent of one another and sealed with one another. During operation, the four cavities solve the problems of lubrication, cooling, heating and heat preservation of the high shear mill.

Description

technical field [0001] The invention belongs to parts of modified asphalt processing equipment, in particular to a four-cavity structure of a high-shear colloid mill. Background technique [0002] With the increase and development of highway construction in our country, adding additives to asphalt or asphalt mixture to improve the performance of asphalt and mixture has been more and more widely used. At the same time, the requirements for the technical performance and production efficiency of the equipment for preparing modified asphalt are becoming increasingly stringent. As the main core of the equipment, the colloid mill has become an independently developed product. The preparation of modified asphalt must be accompanied by high-speed grinding of SBS. This process generates a lot of heat, which can easily damage the colloid mill. This requires water injection to cool down the key parts of the mill. In addition, the grinding temperature of asphalt must reach above 170°...
