Asphalt Grinding Mill Colloid Mill for Emulsified Asphalt and Modified Asphalt
1. Structure and functions
Grinding disc of colloid mill is of unique radial umbrella-shaped six-layer continuous cutting and one-layer grinding structure, combination of both of them realizes polymer hard cutting, grinding and homogenization, and it has low power consumption;
2. Application
Colloid mill can be used for the production of almost all modified asphalt and emulsified asphalt. The operating temperature (medium) is not less than 220 degree centigrade.
In the production of emulsified asphalt, asphalt will be changed into particles of 2~5um after shear and grinding by colloid mill, and then form emulsified asphalt with water-in-oil or oil-in-water structures by different emulsifier.
In the production of SBS modified asphalt, large SBS polymer particles will be cut into small particles more soluble. And strong impact force inside the grinding chamber during shear and grinding will accelerate the solvation between light component of asphalt and SBS, finally SBS can be dissolved uniformly in the asphalt, thus improving production efficiency.
Adopting colloid mill method in the production of crumb rubber modified asphalt can achieve the true modification of the asphalt by the crumb rubber. The manufacturer may adopt crumb rubber with lower mesh (or larger particle size), such as crumb rubber of 30~60 mesh, thus reducing the cost of raw materials. Besides, colloid mill method can also improve the stability of crumb rubber modified asphalt, bring down its viscosity, make it suitable for long distance transport and industrialized production.
3. Processing effects and processing materials
Polymer of 20% can be processed to reach the requirements after one-time processing, particle is even and fineness is small (≤20um);
The colloid mill can produce emulsified SBS/SBR modified asphalt with high specifications (content of SBS/SBR in asphalt is not less than 6%, solid content of emulsified modified asphalt is equal or greater than 75%, content of particles whose size is less than 5um will reach 95%);
