Operating principle of vibrating tables for manufacturing fences and paving slabs

If you are thinking about decorating your plot, elements like a fence or paving slabs come to mind first. Both elements allow you to decorate a house, protect it, and give it a well-groomed look. But both the fence and tiles can be bought ready-made in a store or made yourself. However, with the second option, you should follow all instructions so that the structures retain their shapes even after some time. Let's consider why a vibrating table is needed, how to choose a vibrating table correctly, and what sizes of vibrating tables exist.

How a vibrating table for paving slabs works

A vibrating table, sometimes the term vibropress can also be used, is the main tool when creating paving slabs, fences, curbs, and other elements. Thanks to vibrations, which are responsible for oscillatory movements that expel all air from the mixture, thereby compacting it into the mold. The main advantage possessed by a vibrating table is the ability to eliminate the porosity of any product. The equipment removes all microcracks that can lead to serious problems.

Vibrations enhance gravity on the dense and heavy elements of the concrete mixture. Those particles that settle under the influence knock out all the air and excess liquid to the surface. It must be understood that hardened concrete has a high viscosity, which in turn becomes a barrier to the movement of air bubbles to the surface.

In other words, the mission of the vibropress or vibrating table is to break all bonds that can form after pouring the concrete mixture into the mold. Speaking of the concrete mixture, the simplest components are most often used for its manufacture – sand, working (technical) liquid, crushed stone. Additional elements that strengthen the mixture can be used.

As soon as the concrete hardens, it turns into a monolithic product that is unable to pass moisture, becomes frost-resistant, durable, and integral. When working with a vibrating table, you need to closely monitor the operating time of the equipment. If you overhold it, a very unpleasant situation can occur – the sand and cement will begin to delaminate, which will lead to a loss of density and strength of the product.

How to correctly choose a vibrating table for manufacturing fences and paving slabs

In order to get a truly high-quality concrete product, it is very important to first choose high-quality mixture components, and then auxiliary equipment. For the concrete mixture, it is important, for example, that the sand is clumpy and the crushed stone is of a fine fraction. As for the equipment, when choosing a vibrating table, you need to clearly understand important parameters – amplitude and frequency of vibrations. It is important that in tandem both indicators are evenly distributed over the entire surface. It is desirable that the vibrating table has a horizontal direction. Another important parameter is the thickness of the parts embedded in the table. As for weight parameters, everything is individual here, it can reach up to 250 kg. Usually, the more massive the table, the higher quality and more practical it is.

The design of the vibrating table is very important when manufacturing paving slabs and any other concrete products. Pay attention to the advice in the article to choose a suitable option.
