The UVB -1 productivity of 1 m3 per hour

УВБ-1 (ролет)

UVB-1 bitumen unit is designed for production both anionic and cationic bitumen emulsions, which are used in road construction as follows:

  • base coat on old road top before application of asphalt-concrete;
  • preparation of cold asphalt concrete mixes;
  • surface treatment of road top;
  • thin film protective coats;
  • patch repair of roads etc.

The unit is designed for operation at asphalt concrete production facilities. It can be operated either outdoors under canopy or indoors.

UVB-1 bitumen unit  is semi-automatic, consists of several individual assemblies on a single frame and interconnected by pipelines.

An external source of 6 – 8 bar compressed air is required for operation of pneumatic systems of the unit.

  • pneumatic bitumen valve pos.16;
  • heated bitumen pipeline system, pos.17;
  • heating oil pipeline system pos.18;

The unit if also equipped with temperature and pressure sensors. Pressure and temperature are measured in the following points:

  • water/blend supply;
  • bitumen supply;
  • bitumen to mixer supply;
  • emulsion output.

Pressure is measured in the following points:

  • before the unit;
  • after bitumen pump;
  • before the mill.

The unit is equipped with an emulsifier tank heater:

emulsion tank heater

The heater is a welded flat platform. A 200 liter emulsifier barrel is placed on the platform. A heating agent circulates through pipes in the platform.

The control panel is an air-tight metal case containing «Schneider zelio» controller, multifunction measuring regulators TC4 and TK4, protection and start equipment.
