Our INDENTED CYLINDER SEPARATOR FGJZ series indented cylinder is a grain cleaning and grading machine in all granular grains materials like wheat, barley, rice,corn, oat, millet,oil seeds,peas,beans,coffees,lentils, stones from peas, sticks from sunflower or sugar beet, plastic particles etc., as well as for the extraction of unwanted 
short or long admixtures.

It removes impurities which shorter or longer than you wanted grains, as well as classify grains according to their lengths.

Working principle

INDENTED CYLINDER SEPARATOR material is fed at a uniform rate through the inlet directly into the rotating cylinder. As a result of the indented pockets in the jacket, the material particles  that can be accommodated in the pockets are elevated and thrown into the collection trough.

The material in the trough is then discharged from the machine by a conveying screw; the material remaining inside the jacket or dropping back into it flows via the guiding device to the outlet of the Indented Separator.

Pockets on Cylinder
High efficient to separate materials according to different size

The separating efficiency of the machine can be controlled both by the selection of the pocket size and by adjustment of the separating trough (position of the trough rim).

The high separating efficiency of the Indented Separator is further promoted by the adjustable retarding device installed in the cylindrical section of the Long-grain Separator.

Aspiration connections at the important points of the Indented Separator ensure the dust-free operation of the machine.

Feature

1. This machine can effectively remove both the short and long impurities.
2. The modular design of the components and versatile feeding device make the cylinders change conveniently between series connection and parallel connection.
3. The cylinder is made of highly anti-wear material, so its service life is quite long.
4. The indented cylinder can be detached into two parts, and come with a rapid assembling device. Thus the operators can quickly and easily change the cylinders.
5. The indents are processed with a composite forming technique. The surface of the indented sieve is blunted, thus both the quality and durability can be improved.

Frequently Asked Questions (FAQ)

Indented Cylinder Separator FGJZ Series Cylinder Separator

1. What is an Indented Cylinder Separator FGJZ series cylinder separator?

The Indented Cylinder Separator FGJZ series cylinder separator is a precision grain cleaning and grading machine designed to separate grains and seeds based on length differences. It is widely used in grain processing plants, seed cleaning lines, flour mills, rice mills, feed mills, and agricultural processing facilities. The machine efficiently removes impurities that are either shorter or longer than the target grain and can also classify grains into different length grades.

2. How does the Indented Cylinder Separator FGJZ series work?

The working principle of the FGJZ series indented cylinder separator is based on length selection. The rotating indented cylinder contains precisely engineered pockets (indents).

• Shorter grains or broken kernels fit into the indents and are lifted as the cylinder rotates.

• At a specific height, these particles fall into a collecting trough.

• Longer grains and impurities remain outside the indents and are discharged separately.

This mechanical process ensures accurate grain length separation without damaging the product.

3. What grains can be processed using the FGJZ series cylinder separator?

The Indented Cylinder Separator FGJZ series cylinder separator is highly versatile and suitable for a wide range of agricultural products, including:

• Wheat

• Barley

• Rice

• Corn (maize)

• Oats

• Millet

• Oil seeds

• Peas

• Beans

• Coffee beans

This flexibility makes the FGJZ series an essential machine in multi-grain processing facilities.

4. What types of impurities does the FGJZ series remove?

The FGJZ series cylinder separator removes impurities that differ in length, including:

• Broken grains

• Short kernels

• Long straw fragments

• Unhulled grains

• Long weed seeds

• Oversized foreign materials

It is particularly effective when used after initial cleaning equipment such as vibrating screens or air separators.

5. Why is length-based separation important in grain processing?

Length-based separation is critical for improving grain purity, uniformity, and market value. The Indented Cylinder Separator FGJZ series ensures:

• Higher product quality

• Consistent grain size for milling

• Reduced wear on downstream equipment

• Improved seed grading accuracy

This is especially important for seed processing, where uniform length impacts planting performance and germination.

6. What are the main applications of the FGJZ series cylinder separator?

The FGJZ series indented cylinder separator is commonly used in:

• Grain cleaning plants

• Flour mills

• Rice milling lines
