Explanation of the main structure of the beneficiation shaking table

The beneficiation shaking table, also known as the mineral processing shaking table or gravity concentration table, is a device used for separating fine materials based on their specific gravity. The shaking table consists of a rectangular deck, which is mounted on parallel rails and supported by a frame. The deck is tilted slightly downward, usually at a gradient of about 5 degrees, and is subjected to a reciprocating motion along its main axis by an eccentric mechanism or a cam.

The shaking table deck is divided into several sections, each of which is equipped with riffles or grooves that run parallel to the main axis of the deck. The material to be separated is fed onto the deck through a feed box, and is distributed evenly across the deck surface by a series of water sprays. The water flow is adjustable and can be regulated according to the specific gravity and shape of the material being processed.

As the deck shakes back and forth, the heavier minerals with a specific gravity greater than about 2.5-3.0 are captured by the riffles and settle in the grooves, while the lighter materials are washed off the deck and discharge from the end of the table. The shaking table can be further improved by using a feed launder, which aids in the separation of coarse and fine material by controlling the feed rate and water flow.

Overall, the shaking table is a widely used gravity separation device in the field of mineral processing, and its main advantage is its ability to achieve a high level of separation efficiency for a wide range of particle sizes and mineral types.

Sure, here is a list explaining the main structure of a beneficiation shaking table:

1. Bed surface: This is the main part of the shaking table where the minerals to be separated are placed. The bed surface is usually made of wood, fiberglass or steel.

2. Support frame: The support frame is the structure that supports the bed surface and enables the shaking motion. It can be made of wood or steel.

3. Supporting device: The supporting device consists of springs or hydraulic cylinders that help to facilitate the shaking motion and provide stability during operation.

4. Transmission mechanism: The transmission mechanism includes a motor, a reducer, a belt, and a pulley that provides the power to drive the shaking table.

5. Feed and water box: This is where the mineral feed and water are introduced onto the table. The feed and water boxes are located at opposite ends of the table.

6. Lateral water flow and riffles: The lateral water flow and riffles are designed to provide a steady flow of water across the bed surface to help separate the minerals based on their specific gravity.

7. Discharge port and tailings bucket: The discharge port is where the concentrate is collected, while the tailings bucket collects the remaining material.

Overall, the shaking table works by shaking the bed surface in a reciprocating motion, which causes the mineral particles to stratify based on their specific gravity. The lateral water flow and riffles then help to separate the minerals, with the heavier ones settling at the bottom and the lighter ones being washed away.

The main structure of the beneficiation shaking table is comprised of the following components:

1. Bed surface: The bed surface is the main part of the shaking table and is composed of a bed surface frame and bed surface panels. The bed surface is made of high-quality steel and has a rectangular shape with a sloping surface.

2. Transmission mechanism: The transmission mechanism includes a motor, a belt pulley, a drive shaft, and a gear. The transmission mechanism is responsible for driving the shaking table to oscillate vertically and horizontally.

3. Support mechanism: The support mechanism is located on the side of the shaking table and is composed of a support frame and support rods. It is responsible for supporting the bed surface and ensuring that the bed surface is stable during operation.

4. Feeding and discharging mechanism: The feeding and discharging mechanism is composed of a hopper, a water pipe, and a sluice box. The hopper is used to feed the ore onto the bed surface while the sluice box is used to collect the concentrate.

5. Water supply system: The water supply system is responsible for supplying and distributing water evenly over the bed surface. It is composed of a water tank, a water pump, water pipes, and nozzles.

6. Control system: The control system consists of the control box, electrical control components, and sensors. It is responsible for controlling and monitoring the shaking table's operation.
