Fixed Screening Plant for Diamonds
A fixed screening plant is a type of diamond processing plant that uses a series of screens to separate diamonds from other materials. The screens are typically made of metal or plastic and have different-sized openings. The diamond-bearing material is fed into the plant at the top and passes through the screens. The diamonds are caught in the screens with the openings that are small enough to allow them to pass through. The other materials are carried away by the flow of water or air.

Fixed screening plants are a common type of diamond processing plant. They are relatively simple to operate and maintain. They are also relatively efficient at recovering diamonds.
The components of a fixed screening plant:
A fixed screening plant typically consists of the following components:
- Feeder: The feeder is a device that feeds the diamond-bearing material into the plant.
- Screens: The screens are the heart of the plant. They are responsible for separating the diamonds from the other materials.
- Water or air: Water or air is used to carry away the other materials after they have passed through the screens.
- Collection area: The collection area is where the diamonds are collected.
The operation of a fixed screening plant:
The operation of a fixed screening plant is relatively simple. The diamond-bearing material is fed into the plant at the top. The material then passes through the screens. The diamonds are caught in the screens with the openings that are small enough to allow them to pass through. The other materials are carried away by the flow of water or air.
The diamonds are collected in the collection area. They are then further processed to remove any remaining impurities.
The advantages of fixed screening plants:
Fixed screening plants have a number of advantages, including:
- Relatively simple to operate and maintain: Fixed screening plants are relatively simple to operate and maintain. This makes them a cost-effective option for diamond processing.
- Relatively efficient at recovering diamonds: Fixed screening plants are relatively efficient at recovering diamonds. They can recover up to 95% of the diamonds in the feed material.
The disadvantages of fixed screening plants:
Fixed screening plants also have a few disadvantages, including:
- Can be limited in capacity: Fixed screening plants can be limited in capacity. This is because they are typically designed to handle a certain amount of feed material per hour.
- Can be sensitive to the size of the diamonds: Fixed screening plants can be sensitive to the size of the diamonds. This is because the screens need to be sized appropriately to catch the diamonds.
