Modernization of the UVB-2 unit (20 m³/h) reduced the set up time

GlobeCore anticipates the needs and preferences of its customers – by producing new equipment and upgrading the existing ones. The latest achievement is– an upgrade of bitumen modification plant UMBP-22.

Despite the cost of modified bitumen being more expensive than the cost of usual bitumen its use is practical for the following reasons:

  • temperature resistance of road surface;
  • resistance to cracking of road surface;
  • reduce surface loads;
  • considerable life extension of road surface.

Operating of UVB-2 UMBP-22 plant

Plant is operated by a touch screen control panel. Every part of the device can be activated separately (manual mode) and with preprogrammed algorithm (automatic mode). Control panel also displays readings of temperature parameters and bitumen pressure at different stages of treatment.

Bitumen is preheated to temperature 180°С then pumped from the boiler by external pump. Temperature and pressure parameters are regulated by controls. The flow of bitumen is divided into three parts. First part of bitumen is supplied by a dosing pump to a mixer where it mixes with polymer; second part goes to second mill for more dispersion and homogenization; and the third part is discharged back to collection tank.

Polymer is supplied onto a spiral conveyer/mixer then by horizontal conveyer it is transported into mixer of bulk and liquid materials where it mixes with liquid bitumen. Polymer supply is regulated by rotation rate of electric motor and consequently by the spiral. Dosing of polymer to the plant is set by an operator.

This blend of bitumen and polymer is pumped to a hydrodynamic mixer of the 1st stage. Plasticizer can be also added into the mixer. The mixture is then sent to a colloid mill. Mill cutters coarse grind and blend polymer granules (it is possible to control the gap) and supply the substance to second hydrodynamic mixer.

The second progressive stage consists of the same set of components. High-pressure pump of the second stage takes second part of bitumen from from a boiler and injects it under pressure into the mixer. In the mixer the concentrated polymer bitumen mixture after the first stage and the second part of pure bitumen are mixed. Then it is supplied to the colloid mill of the second stage, for the final grinding of polymer.

After the second stage the modified bitumen is supplied for maturing (storage) to collection tank.

After completion of process the plant initiates algorithm for flushing with fresh bitumen to avoid hardening of left over components.

UVB-2 UMBP-22 Plant assembly components

The unit is supplied mounted on a frame complete with spiral conveyor for polymer supply and quantity calibration and horizontal belt conveyor. Also it includes a loading platform.

UVB-2 Upgrading

Plant is now equipped with temperature and pressure control units of input bitumen, regulating these parameters both before and during process.

Inlet is also equipped with bitumen dosing pump adjusting bitumen amount and frequency with polymer supply in mixer.

Also UMBP-22 was upgraded with an additional polymer mixer. This is a rotor-type aggregate, belt driven by electric motor. Polymer is supplied from a dosing tool into a mixing chamber -a screw conveyer where it is wetted by bitumen from dosing pump and discharged from mixer to pump for further dispersion in the first stage.

There is a new HTF (heat transfer fluid) circulation pump. It preheats a plant before starting work – preparation for work (warming) takes much less time.

Unit has standard transportation size. Equipment inside is laid out to give access to all controlling devices As a result the operating safety of UMBP-22 has been improved.

Container case has shutters at all sides – this gives not only convenient access to plant aggregates but also ensures additional air circulations preventing pumps and engines overheating.

Improving polymerization of bitumen in the SBM-30 storage tank

GlobeСore engineering department completed upgrading  and improving modified bitumen storage tank SBM-30.

The result of this meticulous work is a production of the first two units of upgraded equipment.

The updated model of storage tank SBM-30 has following features:

  • hollow part of the bottom now has a 200 mm heat insulation;
  • overall length is now l 650 mm less;
  • tank operational capacity increased from 27 to 30 m3;
  • new roof shape prevents rain water accumulation;
  • inspection manhole has bigger opening;
  • unit is fixed with brackets on the roof for control cabinet transportation;
  • bitumen level in the tank is controlled by a membrane pressure sensor. Its block is mounted at the bottom of the tank;
  • control cabinet now has a design with two doors. Control panel with indication tools is installed on the inside door. The external door prevents dust and rainfall getting into controls. It has a glass window that allows monitoring sensor readings without opening a control cabinet;
  • new design also includes emergency overflow pipeline preventing hot bitumen spillage  in emergency situations;
  • A model of storage tank is optimized on minimal material consumption,  reducing total weight of equipment by 1000 kg.

The RBE-0.2 mobile bitumen emulsion sprayer unit is a new model for product range expansion

GlobeCore is delighted to inform of yet another expansion of products.

From today representatives of road works companies can purchase RBE-0,2 bitumen sprayers. This bitumen spraying equipment is designed for covering surface with bitumen emulsion by spraying it during asphalt repairs and maintenance of sections of small road and other objects of road facilities. In particular RBE 0,2 is indispensable at construction and repairs of parking zones, pedestrian and cycle lanes.

Visual control of emulsion level is possible through the filling opening. Current emulsion temperature is checked prior to loading by a visual thermometer. If work requires other temperature – material shall be previously heated or cooled. Filling the sprayer with emulsion is carried out through the filling opening.

Sprayer RBE-0,2 has compact sizes allowing it to be used at small construction sites and house yard territories. Hand operated bitumen spraying equipment allows treatment of hard-to-reach places.

GlobeCore RBE models can be bought directly from warehouse. GlobeCore production facilities are located in Oldenburg, Germany. GlobeCore can produce a custom design bitumen sprayer within 45 working days. Bitumen equipment for sale

Main advantages of the new equipment – its mobility and autonomy (owing to diesel engine), that is why it can be used at repairs of yard areas.

Commissioning bitumen emulsion equipment in Zimbabwe

In the end of April 2016 a bitumen emulsion production commissioning ceremony was held in Zimbabwe.

This event was so important that the minister of transport and infrastructure, Mr. Yorama Gumbo, attended it personally. The base of the new production line is a UVB-1 unit produced by GlobeCore. The plant will produce up to 10 tons of bitumen emulsion per hour. The total estimated project cost is 500 thousand US dollars.

Application of high quality bitumen emulsion is reduces repair and maintenance expenses of asphalt-concrete pavements and solves the problem of new roads construction.

With the commissioning of this plant, Zimbabwe can now export bitumen emulsion to neighbouring countries and create 150 new jobs.

Roads of Ghana are Built and Repaired with GlobeCore Equipment

In April, representatives of our company visited Ghana to access the current state of a UVB-1 plant.

This equipment was sold in 2012 and has since produced 40000 m3 of bitumen emulsion. This material is in demand in Ghana, as this country is badly in need of building new and repairing the existing automobile roads.

Application of bitumen emulsions in road construction industry boosts the quality work significantly, expands work season, saves binding materials and fuel. Using emulsions also reduces hazardous emissions into atmosphere.

As a results of the trip, we state that after four years of successful operation in Ghana the UVB-1 is in good state and ready to contribute to the progress of road construction industry of Ghana.

GlobeCore Presents Equipment in Bulgaria

Representatives of GlobeCore presented to participants information both on company GlobeCore and on produced equipment: plans for production of bitumen emulsion and (UVB-1 series), plants for bitumen modification with polymers (UVB-2 series),  as well as laboratory equipment.

Interest of Bulgarian companies to GlobeCore equipment is non-casual. Firstly – there is a constant growing demand for consumption of bitumen emulsion and modified bitumen in this country. Secondly – plant producing modified bitumen equipped with equipment produced by our company successfully works in Varna since 2009.

Presentations were attended both by technical specialists and managers of road construction companies. After completion of an official part all participants received answers for technical questions from Globecore designing engineer.

Our company thanks Bulgarian colleagues for shown interest and warm welcome and also hopes for further cooperation

The Historical Commissioning of Bitumen Emulsion Plant in Tanzania

On October 4, 2014, in  Dar es Salaam (the United republic of Tanzania) there was held an official opening of the bitumen emulsion production plant.

The historical aspect of this event is that it is the first bitumen emulsion plant in this country. And we are happy to inform that it was manufactured by GlobeCore.

This event was visited by the vice-president of the rural and urban road construction of the United Republic of Tanzania – Hassan Matimbe, the representatives of the company-owner Gratian Nshkanabo and Prashant Patel, members of the public and mass media.

Mr Nshekanabo told: “We are pleased to inform that this plant is designed and constructed  according to the best world standards. Bitumen emulsion, produced on GlobeCore equipment, fully complies  with all international standards that will change the existing approaches to the road construction and maintenance.”

The plant is able to produce 10000 liters of bitumen emulsion per hour. In addition, it has created favorable conditions to employ about 100 workers.  We do hope that the commissioning of this plant will favor other branches of industry.

The construction of the first bitumen emulsion production plant is a very important event for any country.  That’s why the representatives of Tanzania carried out a very thorough investigation of the hi-tech market to check the quality of the equipment available and its advantages over the existing analogs. And the preference was given to GlobeCore equipment.

Running Bitumen Emulsion Equipment

On 30 June 2014, GlobeCore employees traveled to European country and conducted a successful launch and commissioning of GlobeCore model UVB-1 intended for the production of bitumen emulsion.

Bitumen emulsion equipment manufactured and supplied by GlobeCore, is increasingly in demand.  This is the result of a wide spread acceptance of and demand for the cold process mix in preparation for the pavement, repair, and construction of roadways.

If you are a company engaged in road repair, road construction, building and structure construction, or production of asphalt mixes, the bitumen emulsion equipment from the Globecore is just what you need!

The GlobeCore UVB- 1 does not emit harmful gases into the atmosphere. Modification of the model with different capacities allow you to select the most suitable model for your specific conditions.  A climate version of the UVB-1 produces bitumen emulsion almost all year round from early spring to late autumn, without stopping earlier programmed processes.
