Types of gold shaking tables
The gold shaking table is divided into different types based on factors such as usage, structure, and function. Here are the common types of gold shaking tables.
- Clasyc gold shaking table: This is the traditional design of the shaking table. It is mainly used for small-scale gold separation. The classic gold shaking table has a rectangular shape. Gum-based paint or rubber products are often used to cover the surface of the shaking table. The covered surfaces have the ability to produce a high friction force. Although the classic gold shaking table is effective and reliable, it requires manual control to achieve the best separation results.
- Concentrating table with fringe: This type of shaking table has fringes around the main separating area. The fringes act to gather additional materials that are close to the borders. Besides that, they help to include additional feedstock into the processing. Consequently, concentrating tables with fringes improve the recovery rate of mineral resources. Moreover, they minimize the risk of missing valuable minerals in waste refuse.
- Wet shaking table: Wet gold shaking tables use water to separate minerals based on density. This table enhances the separation process by reducing friction and dilution. Wet shaking tables are more efficient than dry shaking tables. They are also more applicable in dealing with ores that have a high fine content.
- High-frequency shaking table: High-frequency shaking tables oscillate at a higher frequency than traditional shaking tables. These tables provide rapid separation of minerals. They also enhance processing efficiency and optimize recovery rates. Besides that, the high-frequency shaking tables have longer work surfaces. This allows them to handle larger feed rates. The design of these tables also enables them to accommodate various particle sizes and densities.
Specification and Maintenance
- Dimensions: The standard dimensions for a gold shaker table are usually around 2m in length and 1m in width. These dimensions give the shaker table the potential of processing between 1-2 tons of ore per table daily.
- Capacity: The capacity of the shaker table will vary depending on the ore it is processing. However, the general tonnage of ore a shaker table can process is between 1-5 tons per table per day.
- Included angles: Shaker tables used for gold separation have two included angles of importance. The first one is the angle of the surface, which can vary between 2 and 5 degrees. The other one is the angle of the side dampers, which can vary between 15 and 25 degrees. These included angles create the perfect conditions for gold and other heavy metals to get trapped and be separated from lighter materials on the table.
- Pulsation frequency: The pulsation of the shaker tables occurs through the movement of water. This natural movement creates a kind of wave that pushes lighter materials, like sand and minerals, away from the table, while gold and other heavy metals get trapped in the grooves of the table. The frequency of this natural wave can vary between 60 and 600 cycles per minute.
Gold shaker tables require regular maintenance, and the specific maintenance schedule will vary depending on the make and model of the shaker table. Here are some general maintenance tips for gold shaker tables:
- Inspect the entire shaker table, including all belts, pulleys, and water pipelines, for any signs of damage or water leaks. Report any issues immediately and get them repaired before further use.
- Lubricate all moving parts of the shaker table as per the manufacturer's suggested schedule and lubrication points. This will keep the motor, gearbox, bearings, and any chains and belts running smoothly and working efficiently.
- Keep the working deck of the table free of debris and clean the water channels of any blockages. A blockage in the water channels can cause serious damage to the shaker table.
- Check all straps and cables for any signs of wear or damage and make sure they are securely fastened. Replace any damaged straps or cables immediately, if required, prior to use.
- Daily water check - this is especially important if the shaker table is being used to separate gold in the field. Check that the system's water supply functions properly. Using water of good quality is essential for the smooth functioning of the shaker table.
Scenarios of gold shaking tables
The application of gold shaking tables goes beyond the traditional mining and metallurgy industries. This amazing equipment has found itself a space in diverse industries worldwide.
- Concentration of gold and other precious metals: The main function of shaking gold tables is to concentrate gold and other precious metals. Therefore, it is very common for the shaking tables to be used in goldmines or gold recovery factories. Shaking tables separate gold from other metals based on density differences, leading to the extraction of nearly pure gold.
- Mining industry: Jiangxi province: Jiangxi province is the main mining area of China, with a large number of mining industries concentrating on shaking tables there. The shaking tables are used for the separation and recovery of various minerals, such as tungsten, tin, marble, feldspar, and rare earths, improving the recovery rate and purity of mineral processing.
- Recycling industry: Some shaking tables are also used in the recycling industry. Their work is to classify various waste materials according to their density. It is then possible to separate valuable metals and eliminate non-valuable or harmful substances.
- Education and research: universities and laboratories: Many universities and laboratories use gold shaking tables for educational and research purposes. They study the separation principles and techniques of shaking tables, conduct experiments, and develop new types of shaking tables, which play an important role in scientific research and technical innovation.
- Environmental protection industry: The environmental protection industry also uses shaking tables for separation. Water pollution treatment facilities utilize shaking tables to separate harmful substances to purify water and protect the environment.
How to choose gold shaking tables
Customizing the shaking table is a choice many suppliers are making because it enables them to provide their clients with machines that can meet specific needs. However, before they decide to invest in a custom gold shaking table, they should first understand what advantages and limitations of the table will be affected by the changes made to the table. They should get familiar with the most popular customizations and only opt for them if they are certain about the consequences.
They can start by getting to know the most popular customizations such as different sizes and scales, special shapes and configurations, adjustable frequency and amplitude, surface materials and textures, customized feeding and collection systems, as well as powered and hybrid tables.
Also, before investing in the custom shaking tables in bulk, buyers should first get a sample of the custom tables. The sample will help them examine the quality of the tables to be supplied in bulk. They should also negotiate the prices to avoid overspending when placing a bulk order. Establishing a good supply relationship with the supplier is also important as it enables the buyer to reach the supplier at any time and fast whenever they need to place any future orders.
When looking for a supplier to work with, buyers should ensure the supplier can provide product certification for all custom tables to guarantee compliance with safety standards. They should also inquire whether the delivery cost is included in the end pricing and ensure local technical support is readily available by the buyer's side. Besides, the buyer should ensure the supplier can provide custom tables' repair and maintenance services.
Gold shaking table FAQ
Q1: What ores can the gold shaking tables separate?
A1: The shaking table can separate various ores, such as gold, silver, tantalum, niobium, bismuth, tungsten, ferrous metals, etc.
