Mobile concrete batching plant: advantages of equipment,
Concrete work involves two options - preparation of the material on site or its delivery directly to the construction site. For large amounts of work in the first case, a mobile concrete plant can be used on the basis of a car or on a temporary foundation, in the second case it is necessary to coordinate the time of arrival of the transport. Consider more equipment for the rapid production of concrete directly at the site of pouring.
General information
The design of the mobile concrete plant (MBZ) makes it possible to quickly and easily install it directly on the construction site. This method of manufacturing a concrete mix has a number of significant advantages over a stationary plant, among which it is necessary to highlight the mobility of the equipment.
If the MBZ needs to be transferred to another construction site in another city, one or two vehicles will be enough for this. Due to the modular arrangement of the structure, a concrete plant can be easily assembled and disassembled. Also, installation does not require complicated preparatory work, and its maintenance does not require numerous personnel.
We can confidently say that this type of plant has proven itself in places where it does not make sense to mount a stationary concrete plant of high performance. Installation requires minimal setup time and has high performance. An important feature of the MBZ - a small area, which is necessary for its configuration.
The advantages of equipment
Among the advantages MBZ, when compared with the traditional method of manufacturing concrete, usually note the following:
| Quick installation and commissioning | Subject to the required conditions, the entire cycle for the installation of a concrete plant takes one day. A stationary concrete plant of the same size is usually mounted 8–15 days. |
| Minimum basement price | In this case, the manufacture of a special base for the equipment is not required. It is enough to make a ramp for loading materials, and if an additional cement silo is provided, a foundation will be required for it. At the same time, in a stationary plant, the costs should be increased by 2–3 times. |
| Compact installation | To deploy a mobile plant requires a small area, so it can be placed directly on the construction site. The latter allows you to minimize the cost of transporting the finished concrete. |
| Mobility | The product can be made at any time of the day, the delays on the concrete node and the distance to the object do not affect this. |
| Low cost of transportation MBZ | Thanks to its compact structure, the equipment can be transported on one tractor. Due to this, transportation costs are 3-4 times lower than that of similar stationary plants. |
| Efficiency | MBZ are cheaper stationary. There is no need to deliver concrete to the object, since It is made at the construction site. This fact reduces the cost of transport, as the delivery of sand, rubble, cement and water supply is still much cheaper than the transportation of finished concrete by automixers. In addition, it becomes possible to use plasticizer additives in smaller volumes due to the fact that the product does not need to be carried for a long time. |
| Concrete quality | In this case, the customer always receives fresh concrete, the quality of which is at a high level. He does not need to add water to a product delivered from afar, reducing its quality so that it is easy to lay. It should be noted that the concrete made on the MBZ, easy to lay their own hands. |
| Supply flexibility | MBZ can produce as much product and the desired quality as it is needed for construction. In this case, you can change the recipe for each batch of concrete. |
It is also necessary to note the possibility of quickly dismantling the equipment if necessary.
How to choose MBZ
Делая выбор оборудования для изготовления бетона, следует критически оценивать положительные и отрицательные стороны каждого варианта (см.также статью «Бетонирование дорожек: особенности изготовления»).
Besides:
- Rate the perspective of the enterprise.
- Choose exactly the power plant that will be needed in the near future.
- Consider the planned downtime for maintenance and repair.
- Provide 20–30% stock for production in case of expansion and unforeseen circumstances.
Pay attention to the following equipment parameters:
- performance;
- the volume of storage bins;
- availability of automation (weighing and determining humidity);
- quality parameters of the finished product;
- equipment mobility;
- ease of maintenance and operation.
Tip: if you have difficulty in dismantling old concrete structures, you will need to cut the reinforced concrete with diamond circles, you need density.
Modern technologies offer an advanced management system with hundreds of recipes.
The main structural elements of the MBZ are:
- pump equipment;
- cement hopper;
- engines;
- hot water supply system;
- steam generators;
- pipelines;
- dispensers.
Types of mixers MBZ may be different, for example:
- two-shaft;
- continuous action.
Tip: usually good equipment has accurate tensile weights that provide minimal error when dispensing components.
Factory work
High productivity of the plant is achieved due to:
- construction of the mixer, providing the required amount of ready-made concrete due to the rotation of the axis in a certain way;
- a silo design scheme, which allows compact and without the use of additional labor to produce the product automatically.
Advice: it is not always possible to make a through channel in concrete goods with an ordinary tool; for this purpose, diamond drilling of holes in concrete with professional-type crowns was developed.
The efficiency of MBZ directly depends on the automation of the process. The control system controls all operations carried out by the equipment.
At the same time, electrical devices:
- sensors;
- relay;
- Limit switches,
which are installed directly in the working area on:
- elevators;
- silos;
- dispensers;
- mixers,
must have protection against dust and moisture.
In order to eliminate the human factor in responding to certain events during the process, this work is trusted to computers. The rational use of concrete mixes in construction thanks to MBZ allows you to use its different types on building sites.
Moreover, their composition and quality can be controlled directly at the place of production. This parameter is important because if you follow the instructions for choosing the right mix type, you can save significant financial resources.
To increase the efficiency of the MBZ, their elements are sometimes insulated with sandwich panels. There are also super mobile BZ, which are widely used in the manufacture of roads. This design moves easily along the roadway for the required distance.
Conclusion
From the article it became clear that mobile equipment can reduce construction costs, in particular, new or used mobile concrete batching plant. It has many advantages over the stationary one, among which the possibility of quick assembly and disassembly and the delivery of concrete to the construction site are particularly emphasized.
When choosing an MBZ, it is necessary to take into account the perspective of the enterprise and the necessary equipment capacity at the moment and in the future. The video in this article will help you find additional information on this topic.
