What is a Vibrating Table?

A vibrating table, also known as a concrete vibrating table, is a must have device to consolidate and compact fresh concrete in cylinder and beam molds. It’s used in the construction industry especially for concrete testing and quality control. The vibrating table uses a mechanical vibrator to remove air bubbles and excess water from the concrete, resulting to a denser and more uniform mixture. This process called consolidation will enhance the strength and durability of the concrete. Vibrating tables are used to produce durable and smooth products like tiles, paving stones and precast concrete elements.

Platform is designed to fit various sizes of cylinder and beam molds. Separate control box to adjust vibration frequency and amplitude. Power cable is user supplied and connects to power pulse control unit to operate the table. This will ensure that the concrete is fully consolidated for better quality and performance.

Types of Vibration Tables

Vibration tables are designed for various industries and applications, precast concrete, construction and manufacturing. The types of vibration tables are:

1. Standard Vibration Tables: These are general purpose tables and suitable for many applications. Fixed vibration frequency and used in precast concrete production. Consistent vibration for uniform concrete compaction, a must have in many production environment.

2. Variable Frequency Vibration Tables: These allow adjustable vibration frequency. Ideal for applications where different products requires specific vibration setting. Used in industries where many concrete products are manufactured, provides the flexibility to achieve optimum vibration for each product type.

3. Custom Vibration Tables: These are designed to meet specific customer requirements and can fit unique product sizes, shapes and vibration needs. Used in specialized industries or for large scale production, so the vibration table will match the specific requirement of the project.

4. Portable Vibration Tables: These are designed to be mobile and can be moved to different locations. Used in construction sites, small scale production or where space is limited. Portability does not compromise its effectiveness, a versatile option for various concrete compaction tasks.

Vibrating Table for Freshly Poured Concrete

Concrete vibrating tables remove air bubbles by shaking the freshly poured concrete with a mechanical vibrator. This is necessary to consolidate fresh concrete and form cylinder and beam molds. A concrete vibrating table will compact materials in boxes, bulk bags and containers. The vibrating action will settle the materials, minimize the volume and reduce the cost of transport.

When Choosing a Vibration Table

When choosing a vibration table, consider the following factors to ensure you get the right one for your application. These are:

1. Vibration Frequency: The vibration frequency required for your application should be considered. Different products may require different vibration frequency to achieve the best compaction and perfect finish. Make sure the table can provide the required frequency range for effective concrete compaction.

2. Table Top Size and Material: The size and material of the table top should fit the product being manufactured. A larger table top for larger product and smaller table top for smaller product. The material should be able to withstand the concrete compaction.

3. Load Capacity: The load capacity of the vibration table should be considered to ensure it can handle the weight of the product being manufactured. Overloading the table will cause equipment failure and inconsistent compaction result.

4. Durability and Long Life: The vibration table should be made of durable materials and designed for long life to minimize maintenance and downtime. Investing in a durable table will give you long term reliability and cost savings.

5. Vibration Range: The vibration range should be considered to ensure it can accommodate different products and applications. A table with wide vibration range is more versatile and useful in various production environment.

6. Mold and Product Compatibility: The vibration table should be compatible with the molds and products being used to ensure efficient and effective production. Compatibility will ensure the table can handle the shape and size of the precast concrete elements being produced.

7. Market Trends and Industry Standards: The vibration table should be designed to meet current market trends and industry standards such as energy efficiency and environmental sustainability. Being up-to-date with industry standards will ensure the equipment is relevant and effective.
