Operating principle and construction

VCM P-20 is an inline rotor-stator homogeniser (colloid mill). The premix enters axially and is drawn into the VIMPO MultiShear™ multi-stage proprietary rotor-stator tool, where it is taken in and pre-broken, then sheared and ground in a progressively narrowing wedge-shaped gap and homogenised — all in a single pass. The working gap is set to 0.5 mm for milling and opened to 2 mm for start-up, which keeps the starting torque and current low. The tool has a strong pumping action that supports the feed pump; a positive displacement pump upstream sets the throughput. Housing and stator support are jacketed so that bitumen never cools in the machine.

Frequently asked questions

What is the capacity of VCM P-20?

Up to 20 t/h finished product in a single pass at the reference condition. The positive displacement feed pump sets the line flow.

Why does the working gap open at start-up?

The gap opens to 2 mm at start-up and closes to 0.5 mm for milling. This keeps the start-up torque and current low.

How is the mill heated?

The casing and the stator carrier have a jacket: thermal oil (T) or electric (E),≤ 240 °C. Heat the jacket to operating temperature before start-up.
