MBA manufactures turnkey bitumen emulsion plants capable of producing stable cationic and anionic emulsions in accordance with international road construction standards. Each system is designed to provide accurate dosing, homogeneous mixing, reliable process control, and consistent emulsion quality.
Our automatic bitumen emulsion plant solutions can be configured according to the required production capacity, emulsion type, automation level, and project conditions. The systems are suitable for asphalt producers, road contractors, municipal maintenance projects, and industrial bitumen processing facilities.
What Is a Bitumen Emulsion Plant ?
A Bitumen Emulsion Plant is an industrial production system that mixes bitumen with an aqueous solution consisting of water, emulsifier, and acid in controlled proportions according to the required emulsion grade. The components are processed through a colloid mill for bitumen emulsion to produce a stable and homogeneous final product.
Bitumen emulsions are generally classified as cationic or anionic emulsions. Anionic emulsions are commonly used in insulation and waterproofing applications, while cationic emulsions are widely preferred for asphalt paving, surface treatment, tack coat, and rural road construction.
Compared with conventional hot bitumen applications, bitumen emulsions can be applied at lower temperatures and may reduce energy consumption and operating costs. A properly designed automatic bitumen emulsion plant ensures accurate dosing, consistent particle size, reliable process control, and stable emulsion quality.

How Does a Bitumen Emulsion Plant Work? Production Process
Bitumen emulsion production is based on combining two immiscible liquids—bitumen and water—into a stable and homogeneous mixture with the help of chemical additives. In the MBA Bitumen Emulsion Plant, this process is carried out automatically in four main stages:
1. Preparation of the Water and Chemical Solution
First, water, hydrochloric acid (HCl), and emulsifier additives required to form the aqueous phase are transferred into the stainless steel solution tank. The chemical components are dosed according to the production recipe by means of a high-precision acid and emulsifier weighing unit equipped with load cells.
The mixer inside the tank ensures that the acid and emulsifier dissolve completely and homogeneously in the water, preparing a stable solution for the next production stage.
2. Precision Dosing with PID-Controlled Pumps and Flowmeters
The prepared solution and the hot bitumen, heated to the required viscosity using a thermal oil system or electric resistance heaters, are pumped simultaneously toward the colloid mill.
At this stage, PID-controlled pumps and flowmeters are used for precise dosing and real-time flow measurement. The automation system continuously monitors the flow rates and ensures that bitumen and solution are fed to the mill at the required proportions, for example 60% bitumen and 40% solution, depending on the selected formulation.
3. Micronization and Homogenization in the Colloid Mill
The bitumen and aqueous solution enter the high-speed colloid mill for bitumen emulsion, which is the core component of the production system. Inside the mill, the product is exposed to intense shear forces between the high-speed rotor and stator.
This process reduces the bitumen droplets to approximately 1–5 microns, allowing them to remain suspended in the water phase. The special dual-inlet mill design minimizes air entrainment and prevents foaming during high-speed processing.
4. Stable Emulsion Discharge and Storage
The cationic or anionic bitumen emulsion leaving the mill is transferred directly to the bitumen emulsion storage tank without foaming or phase separation.
The finished emulsion maintains its fluidity and stability even at ambient temperature and is ready for loading into distributors for applications such as surface dressing, tack coat, slurry seal, and road maintenance.

This material selection provides long service life, safe operation, and reliable protection against corrosion throughout the Bitumen Emulsion Plant.
How Can Operators Switch Between Different Road Specification Recipes Such as CRS-1, CRS-2, and CSS ?
Thanks to the recipe storage function and user-friendly PLC software integrated into the Bitumen Emulsion Plant, operators can switch between different emulsion formulations within seconds.
