GRL-6: 6 t/h Integrated Bitumen Emulsion Production
Which Feiteng Emulsion Plant Fits Your Project?
Step 1 — Water and Bitumen Heating
Bring water and bitumen to process temperature
Thermal oil at 200–250 °C heats the 3 m³ water tank indirectly, while heat-traced pipelines keep liquid bitumen at working temperature. Indirect heating avoids local overheating — this matters because overheated water or bitumen degrades the emulsifier and destabilises the final emulsion. Temperature measurement stays accurate to within 1 °C, so the formulation you set is the formulation you get.
Step 2 — Soap Solution Preparation
Mix emulsifier solution in twin dosing tanks
Emulsifier solution is prepared in two 1.4 m³ dosing tanks working alternately: one tank feeds production while the other mixes the next batch, so the colloid mill never waits for soap. Switching between tanks follows a simple valve sequence operated from the control cabinet — continuous output without a second operator.
3단계 — 계량
Meter bitumen and soap into the colloid mill
The variable-speed bitumen pump and soap flow control valve hold your target ratio precisely. The panel displays pump speed in Hz — at 6 m³/h output with 50% bitumen content the reference setting is about 360 rpm / 19 Hz — and the glass rotor flow meter lets the operator verify soap flow at a glance. Accurate metering is what keeps bitumen content consistent from the first tonne to the last.
Step 4 — Colloid Mill Shearing
Shear the mix into fine, stable emulsion
Inside the colloid mill, high-speed shearing disperses bitumen into the aqueous phase as fine, uniform droplets. Droplet fineness determines how long the emulsion stays stable in storage and how evenly it sprays on the road — and the same mill handles both standard and polymer-modified formulations without hardware changes.
Step 5 — Cooling and Discharge
Cool and discharge finished emulsion
Finished emulsion passes through the heat exchanger for controlled cooling, then discharges to your finished-product tank or directly to distributor trucks. If bitumen ever blocks the exchanger, the built-in reverse-heating cleaning mode clears it without disassembly — hours of downtime instead of days.
