Indented Cylinder Separator: High-Precision Length Grading for Granular Material Excellence
Engineered for the Future | Since 2080
The ADDAMS Indented Cylinder Separator (ICS Series) is an essential engineering solution for the high-purity length grading of all granular materials. While traditional screen cleaners sort products by width and thickness, the ICS Series specializes in the longitudinal dimension, making it indispensable for extracting broken grains, unwanted short seeds, or long admixtures like stalks and straw. Whether processing wheat, oats, maize, rice, or even plastic particles, the ICS Series ensures that your final output meets the most stringent international quality standards.
By identifying subtle variations in grain length, these machines can be used as standalone units or configured in series to accomplish complex separation tasks. At ADDAMS, we combine our 15+ years of expertise with robust project management to ensure your seed cleaning line operates with maximum efficiency and zero compromise on product quality.

Operating Principle: Precision Pocket-Based Length Separation
The Mechanics of Indent Selection
The ICS Series operates using a horizontal rotating cylinder. The inner surface of this cylinder is covered with thousands of precisely engineered “pockets” or indents. As the cylinder rotates, the physics of centrifugal force and gravity work together to classify the material.
Stratified Separation Logic
-
Short Product Separation: Grains that are short enough to fit entirely within the indent are lifted as the cylinder rotates. Once they reach a specific, adjustable height, they drop out of the pockets under gravity and fall into a central collection trough. From there, a conveying screw discharges the short product.
-
Long Product Separation: Kernels that are longer than the diameter of the indent cannot fit into the pockets. These remain on the inner surface of the cylinder shell and slide toward the end of the machine, where they are discharged separately as the “long product” fraction.
-
Adjustable Trough Setting: The collection trough can be rotated to change the “drop point,” allowing the operator to fine-tune exactly which length of grain is collected, providing surgical control over the final grade.
Strategic Industry Applications and Sector Integration
Versatility Across Global Processing Chains
The ADDAMS ICS Series is a critical component in turnkey plants, transforming raw natural materials into high-value, standardized outputs across multiple sectors:
-
Grain & Pulse Crops: Essential for separating broken wheat from whole kernels and removing lentils from barley or oats.
-
Oilseed & Nut Processing: Efficiently removes stalks and long foreign bodies from sunflower seeds, soybeans, and peanuts.
-
Specialty Seed Sowing: Used in certified-grade seed preparation to ensure that every seed in the bag has the uniform length required for high-speed automated planters.
-
Industrial Applications: Grading plastic particles or industrial granules where length uniformity is critical for downstream extrusion or molding processes.
Advanced Features and Optional Engineering Upgrades
Optimizing Output and Efficiency
-
Pneumatic Cleaning System: Available on request, a compressed-air system ensures that pockets remain clear of debris, preventing a decline in output during continuous 24/7 operation.
-
Cylinder Inclination Packages: Adjustable inclination (0°–3°) allows for the optimization of product residence time, which is particularly useful for difficult-to-flow materials.
-
IC Splitter Technology: For high-capacity industrial lines, the splitting feature allows for a maximum output of 45 t/h, making it one of the most efficient length separators on the market.
-
Stirring Devices: Specifically recommended for rice or grass seeds, this device increases the efficiency of the “indent interaction,” significantly boosting overall output.
Frequently Asked Questions – Indented Cylinder Separator
How do I choose between round and tear-drop indents?
Round indents are the industry standard for most grains. Tear-drop indents are specifically designed to provide a more aggressive lift for certain varieties, such as oats or rice, where the shape of the grain requires a specialized pocket geometry for precise separation.
Can I change the grading size for different crops?
Yes. The cylinder shell is divided into segments with quick-release catches. This allows your team to swap out one set of grading segments for another in minutes, enabling the machine to move from processing small seeds (1.0 mm) to large pulses or maize (24 mm).
What maintenance is required for the geared motors?
Because we use top-of-the-line direct-coupled geared motors rather than chains or belts, maintenance is minimal. There is no need for belt tensioning or chain lubrication, which reduces downtime and prevents contamination from grease or oil.
How does the trough sealing affect product purity?
The precision seal between the trough and the rotating cylinder shell ensures that “long” products cannot accidentally bounce or leak into the “short” product trough. This is vital for achieving the high-purity results required for certified seed grades.
Is the ICS Series compatible with automated SCADA systems?
Absolutely. All ADDAMS separators can be equipped with electronic speed control and motorized trough adjustment, allowing for full integration into a centralized control room for real-time monitoring and adjustment.
