Asphalt Plant And Its Fundamentals For Road Construction Industry

Asphalt mix consists of liquid asphalt cement and other aggregates and is used as a paving material. One of its most common uses is in the construction of roads.  Asphalt Plants are required for preparing asphalt mix through a series of processes including addition of aggregates in the right proportion, heating, blending and finally discharging for the end use.  Asphalts are available in several grades and specifications and can be either stationary or portable.
How Does Asphalt Plant Work?
Dry raw materials are fed into the cold aggregate silo. The conveyor belts deliver it to the drying drum. Different controlled heating methods are used to dry and heat the aggregates up to a specific temperature in the drying drum. The hot aggregate lifters then collect the hot aggregate and discharge it into the hot aggregate sieving machine. With the help of gravity collector and dust bag collector the hot aggregate lifters clean the smoke and release it into the atmosphere through an induced draft fan. The mixed asphaltic concrete then goes directly to the discharge buffer hopper from where it is settled into the material handling truck.
Advantages Of Using Asphalt Plant
There are numerous benefits of using Asphalt Plant in the road construction process. Some of them are:

  • There is a better control over the consistency of the asphalt mix.
  • Mixing time is significantly less when compared to manual mixing.
  • Asphalt Plants are electronically operated and require minimum manpower and labor.
  • Asphalt Plants come with advanced features such as preset programs for setting feed ratio and time thus there is a better control over the entire process.
  • Asphalt Plants are generally equipped with interlock protection device which helps in avoiding accidents.

Concrete Crushing Equipment

Nowadays, cost-cutting has emerged as an apt weapon to attain success & to remain competitive, & this holds true of the construction industry too. Industrialists are eager to move ahead by using recycled concrete for different construction projects. They have understood the idea that by using the recycled concrete, they can considerably bring down the construction costs. Well, this is where the role of Concrete Crushing Equipment comes into play. The Concrete is first gathered from various destruction sites (sites which have undergone demolition) and then is put through Concrete Crushing Equipment.

Concrete Crushing Equipment: How It Works?
The concrete that can be put through the Concrete Crushing Equipment usually has to be uncontaminated. This simply means that it should be free of wood, paper, litter and likewise materials. Supporting rods made of iron or steel such as rebar can be put through Concrete Crushing Equipment because they can be detached with the help of magnets and other sorting mechanism without needing many efforts. After the used concrete or concrete debris is put through the Concrete Crushing Equipment, the mixture is sorted on the basis the size of the chunks. The large chunks are again sent through the Concrete Crushing Equipment so that they can be crushed more finely. After the process of crushing is completed and the crushed concrete is kept aside, the remaining particles are finally sieved out through a number of processes that include hand-picking as well as water flotation.

Portable Crushing Machine:
Crushing the concrete at the main construction location using Portable Crushing Machine lessens construction costs to a great extent. Level of pollution caused by a Portable Crushing Machine is lesser as compared to that emitted due to shifting material to and from a mine. Furthermore, large Portable Crushing Machine can crush the concrete almost up to 600 tons per hour and even more depending on the efficiency level. The Portable Crushing Machine usually consists of side ejection conveyor, a rubble crusher, display plant, and a conveyor to recycle the oversize concrete chunks.

Other types of Concrete Crushing Equipment:
Among the Stationary &  Portable Crushing Machines, there are Impact Crushers, Jaw Crushers, Cone Crushers, Vertical and Horizontal Impactors and several other types of Concrete Crushing Equipment, which are compact and autonomous. These Concrete Crushing Machines are efficient enough to crush up to 150 tons of concrete per hour.

Information About Cement Mixers

Earlier cement, which is one of the commonly used construction materials, was mixed by hand and the process undeniably used to consume a lot of time and efforts as well. But thanks to latest technology, construction industry witnessed the advent of Cement Mixers that have considerably simplified the task of mixing cement.

Cement Mixers: Types And Components
Basically, there are two types of Cement Mixers. The first type is relatively small and can be used at home, whereas the second type of Cement Mixer is typically a truck that distributes the previously mixed cement to different construction sites. By and large, all the modern-day Cement Mixers have built-in drums wherein the cement is finely mixed. There is a drive unit that ensures the continuous rotation of the mixing drum or barrel. Then there is a loading shaft (also known as chute) positioned at the top of the mixing drum. The ingredients that have to be mixed are channeled into the moving drum through the shaft. Besides, there is a long trough which can be used to adjust the angle that is generally maintained by the position of the drum. The mixing drum  houses paddles that allows the aggregate, cement and water to mix thoroughly .

Functioning Of Cement Mixers
The mixing drum of the Cement Mixer contains blades that are usually placed at a slant to the axis, positioned at the middle of the drum. These blades move towards the direction of longitude. The aggregates are poured in through the upper shaft and the drum is set to start revolving. The main engine is run by a hydraulic gear and helps in rotating the drum. Once the mixing drum starts revolving, water in specific ratio is added to the cement mix. The mixture then keeps on revolving till the time it is finally stopped.

Process Of Pouring The Mixture In Cement Mixers
For getting the cement mixture out of the mixing drum, the rotary motion is upturned. The slant of the blades drives the cement in the direction of the opening of the barrel or drum. The cement is thus poured out of the barrel on top of the chute or shaft. The chute then can be shoved towards the projected site for further usage.

Portable & Towable Concrete Mixers are mainly vehicle driven (generally truck) used for transferring concrete batches to a number of construction sites which may include roadways, pavements or sidewalks. Also known as Mobile Mixers, Portable Concrete Mixers come in different sizes and concrete mixing capacities.

Rough Terrain Mixers:
Their working of Rough Terrain Mixers is very much similar to any Standard Concrete Mixer, the main difference being that these types of Concrete Mixers can transport the mixture over rough terrains even when laden with cement. These Mixers have built-in slewing drum and can be used for mixing concrete of any grade. These types of Concrete Mixers are ideally used at remote locations; nonetheless they can be used at urban sites as well.

Volumetric Concrete Mixers:
Perfect blend of a cement mixing truck and a batching plant, Volumetric Concrete Mixers have separate compartments for storing the materials required to form concrete. The aggregates and water are measured and added to cement in Volumetric Concrete Mixers as per the requirement. Volumetric Concrete Mixers are comparatively efficient and can be transported to different construction sites quite easily. These types of Concrete Mixers too just like the Rough Terrain Mixers can be used for mixing concrete of any grade.

Standard Transit Mixers:
Standard Transit Mixers are ideal for mixing concrete in large amounts. Having built-in large moving barrels, these Concrete Mixers are ideal when ready-mix concrete is required. Usually the drums carry up to 10 cubic yards of Concrete.

Asphalt Plant – Road Construction Machinery

The most commonly used of all kinds of Road Construction Machinery ‘Asphalt Plant’ is a machine in which Liquid asphalt stone and likewise aggregates are heated and blended to produce Asphalt (blacktop) – the material used for making roads.
Asphalt Plant: Earlier Use And The Present Scenario
In the past, an Asphalt Plant could only be used at the construction site where there was immediate requirement of Asphalt. The reason behind this was the deficiency in technology that could only be utilized to keep the blacktop at the right temperature till the time it was ready to be used. Nowadays, thanks to the advanced technology, the Asphalt Plants facilities incorporate Silos to  be used for storing asphalt for many hours and even  days before it is finally used. The Asphalt Plant made using the latest techniques consist of insulated storage towers (silos) that usually have built-in heating system. Moreover, most of the Asphalt Plants these days are based on the technology that reduces noise as well as pollution. For instance, the modern-day Asphalt Plants come with scrubbing arrangement in smokestacks averting the discharge of pollutants in the air. Similarly, special built-in dust collectors can efficiently eliminate the problem of black, dirty vapors released from these Asphalt Plants.
Different Types Of Asphalt Plant:
On the whole, Asphalt Plant can be categorized as Batch Plants and Continuous MIX. The first type of Asphalt Plant i.e. Batch plant is very precise and has  great control of the proportions of the aggregates asphalt & fillers if applicable ,this plants are much more expensive than the Continous Mix Asphalt Plants. The Continuous Asphalt Plant gives out the highest output on a continuous process and are much affordable and with today’s  newest technology they can also produce high quality asphalt.   Both types of Asphalt Plants have common features and equipment like the Cold feed bins were aggregates are stored and bitumen tanks were the liquid asphalt is stored and kept at the right temperature . Both types of plants need have a pollution control systems which are either wet scrubbers or bag house .
