For a month (8 June to 8 July this year), GlobeCore engineers visited Accra (Ghana).

The engineers assisted with assembly and commissioning of a full scale bitumen emulsion production complex there. An important part of the complex is GlobeCore equipment for the production of cationic or anionic bitumen emulsions. Note that our company also manufactures storage containers for bitumen emulsions and modified bitumen, bitumen filters and laboratory equipment for the development of binding material formulas. The bitumen emulsion produced complies with quality standards and is successfully used in road construction and repairs. Commissioning was combined with training of the customer’s personnel to operate the equipment.

A similar GlobeCore bitumen emulsion complex has been commissioned in Ghana previously. The facility has been running successfully for two years; the new facility further increases the bitumen emulsion production in this country.

During 8 – 13 July 2018 GlobeCore officers visited Myanmar.

The main aim of our officers was to commission an 8 cubic meter per hour UVB-1 bitumen unit and to train client personnel.  We should mention that this unit is designed for production of cationic and anionic bitumen emulsions  and will be operated in a suburb of Yangon.

The UVB-1 features semi-automatic operation and is equipped with a water phase section, emulsion preparation section, controls and piping to supply water phase solution and thinner. Bitumen emulsion made with GlobeCore equipment fully comply with international quality standards.

Bitumen emulsion and bitumen modification units are available from our company. To receive information or make an order, please refer to the contacts page of our website.

Dear Customers and Visitors of our site! We would like to remind that our company GlobeCore provides an opportunity to increase the existing bitumen-emulsion equipment results. Our engineers produced an additional block. We should mention that additional block has the potential benefits in the form of efficiency and functionality.

According to this, it allows to raise up the productivity of prevailing GlobeCore equipment. For example, such project was implemented in Thailand, where the existing equipment was complemented with a water phase extension section.

For questions and consultation  please contact our managers by tapping the contacts.

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  plant UMBP-22.

Despite the cost of modified bitumen being more expensive than the cost of usual bitumen its use is practical  due to  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

Bitumen 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  bitumen plant assembly components

The bitumen plant 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

Bitumen 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.

Bitumen plant 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.

GlobeCore representatives took part in the 8th “Bitumen & Asphalt Conference & Exhibition” international conference in Sri Lanka on 1-3 November.

Here is a brief photo report from the conference.

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.

Upgraded Design of Modified Bitumen Storage Tank SBM-15

Very important among bitumen equipment are modified bitumen storage tanks. At the requests of customers GlobeCore engineering department upgraded the existing design of modified bitumen storage tank SBM-15.

In particular a new structural design of a storage tank with downwards pointing cone bottom solves the problem of heat loss in the bottom part. Hollow part now has a heat insulation 200 mm thickness minimum.

The new model has 500 mm less height (length) and now it becomes possible to transport two storage tanks by one 20 ton semi- trailer truck with interior dimensions 2,45 m х 2,6 m х 13,6 m. Operational capacity of modified bitumen storage tank SBM-15 has been increased from 15 to 15,5 m3.

Roof shape doesn’t allow accumulation of rainwater. For safe operation it is covered with corrugated sheet, fitted with dismountable technological fence and with ledge around the perimeter. Inspection manhole now has a bigger opening and is equipped with non-removable grill.

For measuring height of bitumen level in storage tank there is a membrane pressure sensor. Its block is mounted at the bottom of the tank. Sensor readings are shown on the control panel. To control temperature of bitumen there are two shell cases with temperature sensors located at different depth in a 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 gets to control panel. It has an inspection window that allows monitoring sensor readings without opening a control cabinet.

New design also includes emergency overflow pipeline preventing spillage of hot bitumen in emergency situations. This inlet can also be used for additional bitumen circulation. To prevent buckling of outside plating while mounting a tank into operational position – a lower support has been added with cylinder fixing pole which is can be used a transportation support.

28 April 2016 Zimbabwe’s Bitumen Emulsions Production Plant started its work with an opening ceremony.

The symbolic start was made by Transport and Infrastructure Minister Dr Joram Gumbo, who cut the ceremonial ribbon.

For GlobeCore this event was significant because the new facility is based on the GlobeCore UVB-1 plant. Other auxiliary units were manufactured locally. The total cost of this project is estimated at $ 500,000. The new plant is set to produce up to 10 tonnes of bitumen emulsion per hour, as well as create 150 new jobs.

Joram Gumbo noted that his country used to import 250 tons of asphalt emulsion on average each month, which amounted to not less than 1.5 million dollars a year. The new plant will not only cover the internal needs of Zimbabwe, but will also allow exporting bitumen emulsion to neighboring countries.

 

Opening of a new service center in Houston

Dear customers! We are pleased to announce excellent news.  A new GlobeCore service center opened in US

Now GlobeCore equipment and customer support services have become more accessible and operational.

Visit us. We are located on 1750-H Dickinson Ave (FM 1266) Dickinson, TX, 77539.

Call our office:  1-713-429-1616 and + 1-713-828-7877.

Addresses of other offices can be found in the section “Contacts”.

GlobeCore provides customer support during design and production of equipment, and also during its operation.

GlobeCore staff periodically visits units in operation to monitor their condition and share experience. At the beginning of 2016, the choice fell on Ghana.

Transport infrastructure of Ghana is represented by railways with total length of 1300 km, and roads 39.41 thousand km in length, out of which 11,67 thousand km are roads with hard surface. Also in operation are 12 airports and airstrips and 2 seaports.

Despite the fact that Ghana is one of the leading countries in West Africa to be provided with road infrastructure, this figure is inadequate. In addition, most of the existing roads need major repairs.

Using bitumen emulsions allows to:

• create long-lasting and high-strength road design;
• carry out road works at low temperatures and high humidity;
• reduce amounts of binder;
• save fuel in production of “cold” emulsion-mineral mixtures;
• reduce harmful emissions into the atmosphere.

These factors contributed to the fact that four years ago a UVB-1 unit from GlobeCore appeared in Ghana. During the operation it produced 40,000 m3 of bitumen emulsion!

The inspection showed that the equipment is in excellent condition and ready to further contribute to the development of road construction industry in Ghana.
