Buying new concrete vibrators is a significant investment. With several types of concrete vibrators available and multiple applications across industries, companies can find it challenging to determine which type and model will best serve their business and project needs. Using a concrete vibrator buying guide can help you discover the right tools to help on-site. 

How Do Concrete Vibrators Work? 

Concrete vibrators work to release air bubbles that form in concrete after pouring it. By vibrating the concrete, it allows air bubbles to move toward the surface and out of the pour, creating a stronger concrete structure with fewer weak points. 

Consolidation is the process of using the concrete vibrator to dispel air bubbles. Depending on the concrete vibrator you choose and your pour size, you will use different techniques, like varying depth and insertion levels and removal speeds. These factors will help ensure you remove the most air bubbles possible from your concrete pour. When consolidating over an existing pour, you need to remove air bubbles from the previous layer as well, which will help prevent cold joints from forming. 

Understanding how concrete vibrators work can help you better prepare for your next project, including how to prepare the concrete to ensure its quality. 

Types of Concrete Vibrators 

When preparing for your next project, it is essential to select the right concrete vibrator type that meets your concrete and project specifications. There are three main types of concrete vibrators with different processes and purposes. 

1. Formwork Vibrators

Formwork concrete vibrators attach to the exterior of your concrete pour and use pressurized air or electricity to power vibrations through several points. You determine placement points by the pour&#;s thickness and mass to optimize air release. Placement point intervals are usually around 6 feet in length for flexible reach. 

This method is popular for pours challenging to navigate because of the container shape or objects supporting the construct&#;s interior, like poles. Workers typically use formwork vibrators when working with precast concrete. 

2. Surface Vibrators

Surface concrete vibrators work at the surface of your pours and work their way through them. They are better for shallow concrete pours, especially those less than 6 inches deep. This type of concrete vibrator is helpful when concrete has a lower ratio of concrete to water, but avoid using this one with deep or thick mixes. 

Surface vibrators are popular choices when you want a polished final product &#; it results in a smooth finish on the concrete&#;s surface, so you can control your project&#;s aesthetic with a surface vibrator. 

3. Internal Vibrators

For another air and electric concrete vibrator, you can use internal vibrators. These hand-held electric concrete vibrators are some of the most popular types and require a specific consolidation process. It&#;s comprised of a metal tip containing the vibrator that connects to a flexible rod, attaching it to the motor. 

This concrete vibrator functions by quickly working down into the concrete and working your way up slowly, allowing the air bubbles to move higher before the metal tip passes them. 

The most popular internal concrete vibrators in the US today are the Series AX Flexible Shaft Concrete Vibrators.  The flexible shaft allows for full immersion applications and a high degree of control over the vibration.  Their rugged design and single phase engine make them ideal for many concrete vibration applications.  

The FOX motor in the AX Flexible Shaft Concrete Vibrator turns the flexible shaft in the vibrating hose, generating reliable, consistent vibration at the lowest cost on the market.  

 

What Are the Best Concrete Vibrators? 

Choosing the best concrete vibrators for the job can help ensure you produce quality work for your clients. Highly-rated equipment can offer additional benefits, like increased flexibility or more efficient cleanup times. Exploring your options when investing in a concrete vibrator can help you determine the ways your equipment can add to your projects and sites.

Screening equipment can fit into different points of a material handling operation, depending on the aggregate processing application at hand.

Screens size and separate material after crushing, but they may be integrated just after the primary crusher &#; as in most crushed stone plants. Screening also occurs just before stockpiling or material transport.

The bottom line is, you need screens. But choosing the right ones &#; especially if you&#;re new to the industry &#; can be complicated. To ease your pain, here are some key points to consider as you prepare to purchase or lease new, high-tech screen machinery.

An art and a science

Separating and sizing material is a bit artful yet very much a scientific process. According to Pit & Quarry University&#;s lesson on screening, &#;the art of screening lies in the meticulous fine-tuning, tweaking and synchronizing of screen setups within a near-limitless number of applications. Its science is stratification.&#;

Stratification is a big word for the separation of large and small particles. Screening machines achieve this through vibration or agitation of material, although that vibrating movement may be mechanically different depending on an operator&#;s particular needs. No matter what, stratification is the reason screening works.

Machines to consider

There are a couple of screening equipment types: incline and horizontal configurations. Producers should have a good understanding of their operating parameters and overall production goals to make the call on which screen works best.

In addition, there are several options related to how screens run that need to be considered. Producers need to evaluate their requirements for feed tonnage, screening area, and efficiency to guide their choice.

Make the wrong equipment selection in screening, and a producer may be introducing the biggest bottleneck to the entire flow of the production process.

Incline versus horizontal

Incline screens harness the power of gravity to reduce power consumption. As a result, the incline configuration has better capacity abilities when operating at similar speeds versus horizontal screens.

Of course, if producers are limited by vertical clearance challenges at a quarry or mine site that would prevent the incline from being constructed at the proper angle &#; often about 20 degrees on the top deck &#; they will have to choose a horizontal screen.

Consider, too, that horizontal screens are commonly used in portable plants &#; or if producers are feeding from a dredge in a water-intensive operation.

Motion differences

There are three main ways screens move to achieve the necessary stratification.

Horizontal screens typically vibrate with either linear motion or an elliptical motion. Both movement patterns are effective, but the linear motion produces high G-forces that can dislodge material and convey it forward across the screen.

Inclined screen machines can also vibrate in linear or elliptical patterns, as well as in a circular motion, which is often preferable in continuous-feed setups where screening of large material must be accomplished.

Other considerations

In addition to considering an incline or horizontal screen and how they should vibrate to provide the desired output, setting up a screening operation requires producers to consider a couple of other points:

Dust suppression. Screening is one of the bigger drivers of dust in operations. A producer&#;s screening equipment should incorporate dust covers that physically block dust from escaping machinery &#; a dry suppression tactic.

Producers may also want to consider wet dust suppression techniques, depending on the material they&#;re working with &#; especially if they&#;re subject to the Occupational Safety & Health Administration&#;s new silica standard.

Feeders. Per Pit & Quarry University: &#;Depending on the process stage, the material to be screened is fed to the screen from an intermittent-feed-loading device like a wheel loader or from a continuous-feed device like a hopper or a conveyor.&#; In other words, producers must understand whether their operation&#;s production goals require the use of continuous or intermittent feeding tactics.
