Before you purchase equipment for the production of asphalt, it is recommended to determine what types of this material are, what stages the production technology of the product consists of, and also what is required for work.
Varieties of the presented product
Asphalt consists of several components: sand, gravel, limestone, gravel and bitumen. The latter glues all these elements into a single mass. As for the classification of the material presented, it is very simple. Depending on the components that make up the mixture, asphalt can be divided into the following types:
- gravel;
- sandy;
- crushed stone.
Naturally, the material is classified by the method of installation (cold, warm and hot).
Business Advantages
Before you buy equipment for the production of asphalt, you need to decide whether to open your own business. Naturally, the manufacture of the building material presented has its advantages:
- there is a demand for it;
- for work, the most common components are used that do not need to be searched abroad;
- for manufacturing, you can use small mobile plants (in this case, asphalt is produced right at the place where it will be laid, and this, in turn, will save on delivery).
However, there are also disadvantages in this matter. For example, equipment for the production of asphalt has a high cost. In addition, the product in question is not always needed. That is, asphalt is most often laid in the warm season, although repair work is not excluded in the winter.
What equipment is needed?
In order to produce this material, you will need the following:
- crushing equipment, which sorts and breaks the stone (crushed stone) into certain fractions;
- receiving areas for storage and supply of all necessary components: sand, bitumen;
- special containers for PVA;
- a heating chamber, which is able to provide and maintain a temperature of up to 200 degrees Celsius;
- mixer;
- devices for loading components;
- devices for unloading and storage of the finished mixture.
Mini-plants: varieties and features of use
So, the installation for the production of asphalt is especially popular. It is easy to manage, fully automated and mobile. That is, it can be moved from place to place with the help of a tractor. However, if you decide to take this matter seriously, then you will need to purchase larger instruments.
The mini-factory for the production of asphalt is in great demand. The fact is that it can produce a large amount of material per day, in addition, it is equipped with all the necessary devices. Naturally, its cost is also high (about $ 80,000). However, the price is consistent with the quality. Choosing such equipment should be very responsible so as not to purchase a defective line that does not bring you anything but high costs.
There are several types of mini-factories:
- Cyclic, which have additional devices (roar and tower). Such plants are capable of producing about 50 compositions of asphalt concrete in 24 hours. However, they are stationary, so you will have to provide for the costs of delivering the material to the place of repair work. Naturally, this increases the cost of the final product.
- Continuous.They are very easy to operate, can be transported, do not have additional devices and towers. The disadvantage of this installation is that it cannot independently crush stone and gravel, and this somewhat complicates the work.
Material manufacturing technology
This procedure is carried out in several stages:
1. The selection of the necessary components. That is, you have to carefully examine all the components for compliance with certain sizes. At the same stage, the preparation of the components is carried out: cleaning, sifting.
2. Drying of the feedstock. It is made in a special drum.
3. Heating of bitumen in tanks.
4. Mixing of all components in a special mixer, in which a certain temperature should be maintained. Note that the quantitative ratio of all components must be strictly controlled to get a mixture of the necessary consistency. During mixing, the asphalt can be sieved through suitable sieves or divided into the desired number of portions.
5. The receipt of the finished material in the storage hopper.
6. Unloading and transportation of the hot mixture to the place of repair work.
It should be noted that asphalt production technology is not complicated, therefore, even a beginner can master this business. Naturally, for this you need to carefully calculate all the costs and draw up a business plan.
