Emulsified Asphalt Colloid Mill

Product Overview

The Emulsified Asphalt Colloid Mill is a new generation of asphalt SBS crushing, mixing, and homogenizing equipment, which is domestically produced based on advanced German colloid mill technology. It is also a crucial equipment for mixing and crushing colloidal sticky substances with hard granular materials during the homogenization process. The product boasts attractive appearance, stable operation, powerful functions, and reliability. Its performance is comparable to similar products from overseas.

Product Principle

Modified asphalt colloid mill - Main structure

The modified asphalt colloid mill is mainly composed of three parts: the motor, bearing base, and grinding head. The main unit is installed in a horizontal manner, and the motor typically uses a standard motor, but a explosion-proof motor can also be used. The grinding head's crushing chamber is generally made of stainless steel through forging, with the main components being forged in alloy and then undergoing several rough and fine machining processes before being precision manufactured on a CNC machining center, achieving advanced quality standards. The stator and rotor inside the working chamber can be manually adjusted during shutdown, with the adjustment distance generally being 0.01-2mm. The outer shell of the grinding head is equipped with a heating device, which can be heated using thermal oil or steam. The connection is a flanged design with an inlet at the bottom and an outlet at the top, with the main unit's side being the inlet and the top being the outlet, connected via flange joints.

Main Equipment Composition and Working Principle

The main equipment consists of a modified asphalt colloid mill, followed by an asphalt mixer, quick-open filter, high-shear mixing pump, swelling mixer, and electrical control cabinet, etc.

Key Functions: Initially, SBS is mixed with stabilizers and asphalt, ensuring even distribution of SBS within the asphalt. It then proceeds to the emulsified asphalt colloid mill for crushing. Under the high-speed operation of specialized equipment, SBS is first cut at high speed, ground, and refined. Subsequently, the mixture is subjected to centrifugal force, forcing it to enter the primary crushing and fine grinding zone, where it is re-cut at high speed, ground, and crushed, gradually extending radially. The crushing chamber features one cutting zone and three fine grinding zones. At each grinding stage, the fluid's direction and speed change instantaneously, and it undergoes millions of high-speed cuts, compressions, and grinds, leading to the breaking of liquid material molecular chains, particle crushing, and particle tearing. This results in a high-stability modified asphalt product that does not delaminate, and achieves continuous production, enhancing corporate profitability. The complete set of equipment has production capacities of 2 m³/h, 4 m³/h, and 6 m³/h.
