Types of Gold Vibrating Tables
Thegold vibrating tableis a sort of gravity separation equipment that works on the same principle as a gold shaking table to mine gold by separating gold from other minerals and ore materials. Gold vibrating tables come in different types based mainly on how they are used, the kinds of materials they process, and their overall design.
- Industrial Gold Vibrating Tables: This type of gold vibrating table is commonly used in the mining and metallurgy industries to separate minerals and ores by gravity. As the name implies, an industrial gold vibrating table is built to be robust and heavy duty to last a long time under constant use. Industrial gold vibrating tables are also versatile. They can be used to separate not just gold from other minerals but also a wide range of other materials, making them a staple piece of equipment in many processing plants and mines.
- Laboratory Gold Vibrating Tables: Unlike industrial gold vibrating tables that are built for heavy-duty use and large-scale production, laboratory gold vibrating tables are usually smaller and much more delicate. These tables are often used in scientific research, testing, and educational settings. As the name implies, laboratory gold vibrating tables are built for use in laboratories. Because of their smaller sizes and more delicate constructions, laboratory gold vibrating tables are used to process smaller sample sizes compared to their industrial counterparts. Also, the tables are used for testing different material combinations at low volumes to help researchers determine what methods should be used when working with larger quantities of materials.
- Plastic Gold Vibrating Tables: Most gold vibrating tables are manufactured from metal. An exception is the plastic gold vibrating table, which is made from strong plastic materials. Plastic gold vibrating tables are used for light material processing. They are also more affordable and easier to handle when compared to metal gold vibrating tables. Because of these characteristics, plastic gold vibrating tables are more commonly used in schools and hobbyist settings for fun rather than serious scientific pursuits.
Specification and Maintenance
The following are specifications for the gold ore vibrating table, also known as the gold concentration shaking table:
- Size: The length of the table is between 0.9m and 2.6m, while the width ranges from 0.5m to 1.1m. Shaking tables are available in various sizes to suit specific purposes.
- Capacity: The shaking table can separate up to 3-19t of ore per unit every hour. The capacity depends on the table's dimensions and the level of concentration of the material.
- Frequency: The table shakes at a frequency of 300-600 cycles per minute. Some tables can vibrate at higher frequencies to increase separation efficiency.
- Power: The shaking gold table uses between 0.5kW and 2.5kW of power. The power consumption depends on the size of the table and the frequency of the vibrations.
- Recovery rate: The shaking table can recover between 90% and 98% of valuable minerals, depending on the concentration of the material being processed.
Maintenance
Regular maintenance will improve the performance, durability, and separation efficiency of the gold shaker table. Here are some simple maintenance tips:
- Lubricating the bearings: Lubricate the bearings at least once a month. Make sure to use quality grease that can withstand various environmental conditions and temperatures.
- Inspection of the table: Carry out inspection and maintenance of the shaking table every week. Check all the mounts, fasteners, and support structures for signs of wear or deformation. Do necessary repairs, or replace any worn or damaged parts to avoid any failures during operation.
- Cleaning the shaking table: The vibration gold table's surface should always be clean to prevent the build-up of mineral residue and debris. Regularly clean the surface with high-pressure water to remove any contaminants. A clean surface will enhance the separation efficiency of the table.
- Adjusting the slope and water flow: Over time, the slope and water flow may change during operation. So, it is advisable to adjust them based on the material being processed and the separation required. A suitable slope and water flow will optimize the separation efficiency.
Scenarios of gold vibrating tables
A gold vibrating table works in the mining industry. It focuses on separating valuable minerals and ore fragments from other worthless materials based on size, weight, volume, and shape differences for improving the quality of the final gold extract. Conducting these separation processes is the main function of vibrating tables in gold mining.
Vibrating tables are usually made out of robust and fine materials. They are strong, stable, long-lasting, wear-resistant, vibration-damping, and good-loading capacity, which can also be used in other mining industries and fields but for different minerals, gemstones, and ores.
The following are some value-adding uses of vibrating tables in various ore and gemstone mining industries:
- In the gem and jewelry mining industries, valuable gems like diamonds, sapphires, and rubies are separated from chips or ore fragments with vibrating tables. The quality of the tables is inspected to ensure that no valuable gems are lost in the residue.
- In the agricultural industry, vibrating tables are used for seed separation. Heavy seeds are separated from light or damaged seeds on these tables. Properly farming seeds are then used for better crop production and increased yield, which adds value to the agricultural industry.
- Vibrating tables can also be used for ore or minerals sorting after an initial crushing has taken place. Different minerals, like copper, iron, aluminum, and nickel, are separated according to their weights or densities before further processing and refinement takes place. These minerals can then be sold separately, adding value to the industry and supply chains.
- In the coal mining industry, vibrating tables are used to separate valuable coal from other unwanted minerals and ores. The quality of the coal is increased by this separating process, and pure coal is sold, which adds value to both the mining industry and the end-users of the coal.
