Different Kinds of Concrete Vibrator Machine
A concrete vibrator machine is utilised for a variety of applications within the construction industry. They are available in a wide variety of forms and dimensions. In the construction of buildings, roads, and railways, its primary application is in the process of compacting concrete. Consolidation is the method of taking out trapped air and excess water from freshly poured concrete before it is allowed to cure. The purpose of this step is to firmly establish the concrete in the desired location within the form-work. This is done to ensure that the concrete is properly consolidated and to reduce the likelihood of defects in the final product. These vibrators have been built with a frequency range of vibration that extends from 2800 to 15000 revolutions per minute (rpm).

There are four distinct varieties of concrete vibrator machine. Let’s take a look at each of them in more depth:
Types of Concrete Vibrator Machine
- Internal Vibrators:
This type of concrete vibrator is also referred to as a needle or poker type of vibrator. A compact steel cylinder with an attached electrical cord makes up the internal concrete vibrator. This device is used to shake the concrete from the inside out. The head of the vibrator is immersed in the wet concrete as part of the process. It is a high-frequency vibrator that is intended to function anywhere between 12,000 and 17,000 vibrations per minute. There is a wide spectrum of amplitudes, from 0.015 to 0.08 inches. The vibrator operates at a frequency of approximately 700 cycles per minute. When the vibrating head of the machine is in contact with the concrete, it performs at its highest level of efficiency. When selecting the type of internal vibrator to use, there are a few things that must be taken into consideration, including the following:
- Sources of power include electricity, gasoline, pneumatic, and hydraulic systems.
- Location of the power unit: either inside or outside of the vibrating head
- Characteristics of the head, including diameter, length, and shape, as well as the length and type of the shaft.
- External Vibrators:
This type of vibrator for concrete is also referred to as a shutter form vibrator. It includes a base plate in the package. It is utilised in the process of consolidating the newly poured foundation in addition to the compact surface of the precast concrete. The power source is an induction motor with three phases. It is a structure that is completely enclosed. In addition to this, it is tough, dependable, and simple to maintain, and its power cord is made up of four cables that have a rubber coating on them. Castings made of aluminium alloy are typically used to construct the casing. It possesses a motor structure that is both lightweight and extremely efficient. It has the construction pattern that the machine is clamped to the form-work in a horizontal or vertical orientation at suitable spacing not exceeding 90 cm in both directions. This can be done in either orientation. They are utilised in place of an internal vibrator in situations such as thin and congested areas, arches, and tunnel linings, amongst other similar scenarios.

- Surface Vibrators:
These vibrating devices are installed directly onto the concrete mass. When the screening is done, they use vibration to remove concrete from the surface. When combined with concrete that has a low ratio of water to cement, it makes for an excellent choice for compacting shallow elements, and it also works well on its own. When the depth of the concrete that needs to be vibrated is greater than 125 inches (250 millimetres), it is not recommended to use. With the assistance of this machine, even dry mixtures are capable of being effectively compacted. Surface vibrators can take many forms, but common examples include vibrating pans and vibrating screeds. The most common applications for this product include compacting small slabs, as well as patching and repairing work on horizontal surfaces like pavement slabs. It spins at a frequency of approximately 4000 revolutions per minute and accelerates at a rate ranging from 4 g to 9 g.
- Vibrating Tables:
This piece of concrete vibrator machine is used to settle and compact bulk material that is stored in a variety of containers. They can be either electromagnetic or electromechanical, and both types are available. You can select the appropriate type by taking into consideration the container type, the application, the characteristics of the material that is being treated, and the maximum weight that needs to be moved, among other factors. It consists of a steel platform built with a rigidity that is mounted on a flexible spring, and an electric motor powers it. They are simple to operate and can support up to one hundred and fifty kilogrammes. It also has a low overall power consumption despite its high operational efficiency. It functions in a manner that is silent and requires little in the way of upkeep. The testing of welded joints in the automotive and electronic industries, the efficient packing of powders in the chemical industry, and the proper flow of materials in dies to avoid bubbles in moulded parts are just some of the common applications for this technology. Other applications include compacting, detaching, and aerating bulk materials. The use of this machine has a number of benefits, some of which include the addition of more materials into smaller containers and the reduction of waste caused by overflow or spill over at filling stations.

There are many different types of concrete vibrator available, each catering to a specific method of concrete compaction that is necessary to fulfil specific construction and structural requirements. Because concrete is composed of particles of varying sizes, it is possible to achieve optimal concrete compaction with the assistance of vibrators that operate at a range of speeds. As a result, you should begin the search for the type of vibrators that is most suited to your needs by comparing the brief details of each type that were shared earlier in this article. Using this information, you will be able to select a vibrator that will help you achieve the most productive results possible for your project.
