Asphalt is a dark brown or black adhesive type substance that is used as a primary constituent. It also contains bitumen. These types of adhesives are very complicated materials that contain compounds that are both saturated and unsaturated. The differences between these compositions is based on the characteristics of the crude oil.
Typically, asphalt contains:
– 80% carbon
– 10% hydrogen
– 6% sulfur
It also contains trace amounts of oxygen and nitrogen.
Bitumen is a term that is used to describe solid, viscous or semi-solid materials that are either naturally occurring or are manufactured. Bitumen that occurs naturally is acquired when petroleum is processed.
Asphalt is commonly used because of its specific characteristics. For example, it is resistant to water as well as its binding capabilities.
The strength and hardness of road surfaces can be directly contributed to the ability of asphalt being able to bind stone and sand together as one aggregate.
What Are The Components Of A Batch Type Asphalt Plant?
There are several major components of a batch type asphalt plant including:
– Vibratory screen (removes the unnecessary and large materials from the feeder)
– Aggregate feeder (regulates aggregate flow)
– Burner
– Mixing and drying drum (this is where the combining of bitumen and asphalt occurs)
– Conveyor (receives aggregate and feeds dryer)
– Pollution control mechanism
– Control panel (manage quality and quantity of production)
– Fuel tank
– Mineral Filler (feeds minerals to drum)
– Asphalt Tank (offers heat control via insulation)
How Does An Asphalt Batch Plant Works?
The asphalt ingredients are constantly fed into the rotating drum, and this creates a continuous production of asphalt hot mix. The main elements used in hot mix are aggregates, mineral fillers and asphalt.
The aggregates are moved by conveyor to the rotary drum from the bins (feeder). The burner helps to remove all of the moisture content that is in the aggregate. The aggregate is then heated in order to get it to the correct temperature.
The hot aggregate is then coated and mixed with the filler materials and the asphalt, and it is then transferred to vehicles from the drum. This transfer is done by load conveyors.
The feeder bins, the mineral filler and the pumping unit with attached asphalt tank are organized in order to properly maintain the right proportions of the ingredients used for the hot mix.
Any dust that accumulates is collected by the dust collector and goes through the pollution control unit before it is released into the environment.
What Are The Characteristics Of Asphalt?
The design of a highway is influenced by the characteristics of the asphalt that is used. The asphalt gets its characteristics from the asphalt drum mix plant.
This type of plant makes sure that the asphalt that is created should have the correct specifications so it is suitable for use as pavement. It is important to keep in mind that asphalt has several types of functional properties that are able to affect road conditions such as road noise, tire wear and brake efficiency.
Asphalt batch plants can help you produce suitable hot mix asphalt for a highways and roads. The plant can help expand your business and increase the return on your investment.
