If you are looking for a safe, economical and reliable way to melt bitumen, Atlas bitumen decanter is best. It is ideal for material that comes in drums. Road contractors prefer the same. Bitumen sellers also want this to solve availability and logistics issue with bitumen. It can reheat bitumen, and it uses oil to heat bitumen indirectly. It does not change the properties of bitumen.
Using the hot gases, emitted as a result of the hot oil passing through the heating coils. It will heat up the drums. Asphalt inside the drums will melt and fall below. Circulation of thermic oil into the Bitumen Decanter machine allows transfer of heat to the bitumen heating chamber. There are pipelines running inside the heating tank. Pipelines run from the sides of the ramp where bitumen barrels will be passing. Pipelines are also through the bottom of the machine. This area stores bitumen that falls from above.
Some Advantages of Bitumen Drum Decanters:
Bitumen drum decanters offer many advantages over traditional melting of bitumen. Read them below:
- Easy availability of bitumen to remote locations.
- Easy, safe and cheap way to melt bitumen.
- Less time to install.
- Proven and maintenance free design.
- No special operator required for using the machine.
- Diesel burner supplied with thermic heater is fuel efficient.
- It is economical because in a short time it helps melt good quantity of bitumen.
- It controls temperature thermostatically.
- Heating is indirectly by hot gases and this method makes sure that bitumen aging does not take place.
- Since heating is by hot gases the barrels are heated uniformly .
- The heating chamber is fully insulated to minimize heat loss.
- Enough storage of bitumen below allows storing bitumen. It can be pumped out any time required.
- Design is environmental friendly.
Bitumen Decanting Process – Easy to Operate and Simple to Maintain Design
The process of bitumen decanting is simple. Bitumen that comes in drums has to be inserted into the melting unit. These drums are inverted after making hole into their cover on the top. In order to load the bitumen barrels we make use of arms that are hydraulically operated. There are three or more rows for bitumen barrels to get inside the heating zone depending on the capacity of the decanter. When the drums are inside they are in a row. There are 3 or more such rows full with barrels lined adjacent to each other. Surrounding the barrels is a network of pipelines that carry thermic oil.
The heating of Bitumen Decanter is by use of hot gas emitted as a result of the hot oil. This hot oil is passing from the pipelines adjacent and below. The pipelines running below in the chamber have a specific purpose. Bitumen Decanter which is now melting due to heat drops down due to gravity. The pipelines below will help to keep the bitumen in liquid state. Apart from the same, bitumen if stored in the heating chamber for a long time will get solid due to drop in temperature. This happens when the machine is not used for some time. When we start the decanting after few days it will help in melting the Bitumen Decanter stored below. It will also help in melting the bitumen in the barrels.
This heating zone is of MS steel. It is insulated from all the sides by glass wool and it helps in reducing the heat loss. There are spring type doors on each side of the machine that helps to keep the heat inside. We have to feed the bitumen barrels from one end of the machine. As we keep on adding bitumen barrels the barrels will come out from the other end of the machine. The barrels coming out from the other end will be empty. This is because bitumen inside the drums has now melted and flown down due to gravity.
Thermic oil circulation heats the Bitumen Decanter Unit and hence the process is indirect heating. Indirect heating will not change the properties of bitumen. There is a thermic heater provided with the Bitumen Decanter machine that is fitted with a burner. The thermic heater is three pass type system. It is quiet and efficient system designed to continuously heat the thermic oil. The burner is temperature controlled. It will keep heating the pipelines that carry the thermic oil. The thermic oil flowing to the heating chamber will pass the heat to the chamber. When the oil is pumped back into the heater unit, its temperature is few degrees down. This is because the heat is being transferred for bitumen melting. The thermic oil heater unit comes with a control panel board. This panel helps setting of important parameters.
The pipelines that carry thermic oil are seamless. We test them for any leakages before dispatch. Bitumen Decanter test the main heating chamber for any leakages before dispatching the machine.
Components of Bitumen Decanter Unit:
Exporter and Supplier of bitumen drum melting unit in Worldwide. Below Describe Some Components of decanting machine. We have bitumen decanters installed in Myanmar, Oman, Indonesia and Nepal.
- Heating zone: Heating chamber is of MS material and it is covered on all the sides by glass wool. Lower portion stores bitumen and upper portion holds bitumen drums for heating.
- Heating unit is fitted with hydraulic arms. They will help in pushing the drums inside the chamber.
- Thermic oil heater: It is heating unit for the thermic oil. This oil is heated by the thermic oil heater and circulated into the heating chamber. Once it is circulating, it will transfer the heat to melt bitumen. The burner supplied with the thermic oil heater is diesel fuelled. Other fuel options available are furnace oil, wood and gas.
- Pipelines: Pipelines are all seamless type. They carry the thermic oil from the heater to the heating unit.
The equipment is maintenance free and is with few parts that require attention. It is designed so that anybody can operate the same with little training.
