The UVB-1 productivity of 8 m3 per hour
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 in temperature range from +5oC to +40oC.

* Depends on production recipe!
UBV-1 water-bitumen emulsion unit is semi-automatic and consists of the following components mounted on a single frame:
- emulsion preparation assembly – 1;
- water phase assembly – 2;
- control cabinet – 3;
- lug – 4;
- cover – 5;
- water phase input line – 6;
- flux input line – 7.
Emulsion preparation assembly is a three-stage mixer 3 with pipelines and valves, bitumen pump 1 and rotor mill 2.
DS-185 bitumen pump is driven by asynchronous three-phase motor 5 (18.5 kW, 1500 RPM) via gearbox 6.
The rotor mill drive is motor 2 – asynchronous 11 kW, 3000 RPM.
The assembly is mounted on frame 12 and is equipped with temperature and pressure sensors 8.
Emulsion preparation assembly
1-bitumen pump; 2-rotor mill; 3-hydrodynamic mixer;
4- flux mixer; 5-bitumen pump drive; 6-gearbox;
7- mill drive; 8-temperature and pressure measurement;
9-pneumatically controlled valve; 10-three-way bitumen valve;
11-“bitumen return”; 12-frame.
Water phase assembly
Water phase assembly equipment is fitted with pipelines with visual monitoring indicators for liquid flow 1 and adjustment valves and control devices. The drive is a three-phase short-circuit asynchronous motor at 0.75 kW.
1-flow meters; 2-flux pump; 3-blend pump; 4-water pump; 5-water and blend mixer;
6-measuring vessels for acid, emulsifier and adhesion additive; 7-water input line;
8-water return line; 9- blend tank.
Water is supplied by vertical multistage pump 4, МVІ 807.
Blend is supplied by vertical multistage pump 3, МVІ 207, 1350 RPM).
Flux is supplied by gear pump 2 (nominal flow rate at least 22 liters/minute).
Component flow rate is monitored by flow meters 1:
- up to 10 m 3/hour range for water;
- up to 4 m 3/hour range for blend;
- up to 0.5m3/hour for flux.
The unit is supplied with 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.
Control cabinet
Starting components are installed in the control cabinet. Process parameters are managed by the Schneider zelio controller, which receives signals from the following sensors:
- Autonics TK4S – bitumen pressure after pump; – Autonics TC4S– bitumen pressure after pump;
- Autonics TC4S – bitumen temperature before pump; – Autonics TK4S – emulsion pressure before mill.
The following sensors are used for indications of the parameter measured:
- Autonics TK4S – bitumen pressure before pump; – Autonics TC4S – blend temperature;
- Autonics TC4S – water temperature; – Autonics TC4S – emulsion temperature before mill.
