Bjerke Brothers, Inc.‘s NS Series is the industry’s leading line of indent cylinder length separators, and offers a full range of sizes, capacitiesand configurations to meet every length separation application. With a modular design and two cylinder sizes – the NS-B and NS-S Series – numerous variations are available, with capacities ranging from 160 bu/hr up to 6000 bu/hr.
Rigid enclosed frame construction and poly belt chain drives provide smooth, vibration-free performance with low energy consumption. Manufactured to the highest standards, all Crippen Northland Superior Indent Separators require only routine maintenance to ensure years of trouble-free operation. All parts subject to wear are readily accessible and easy to replace.
The rotating 23″ or 17″ diameter indent cylinder, case-hardened for optimum life, is the key component of the NS series separators. Available in a wide range of indent pocket sizes, NS cylinders can remove large or small material as desired to meet every separation requirement.
Simple operating adjustments allow for a wide variation of products to be separated by the NS Indent Cylinder Separators. The separating edge (A) can be raised or lowered, allowing the receiving trough (B) to catch desired liftings of shorter grains as they drop free from the cylinder indents (C). Turning the hand wheel (D) adjusts the position of the separating edge, with the pointer (E) showing the position on the indicator dial (F). The inspection door (G) allows observation of the cylinder separation process.
The liftings are transported out of the receiving trough by a screw conveyor. Grain line blades (H) connected to the bottom of the trough ensure a steady grain flow along the length of the indent cylinder. The flow of the unlifted longer material (tailings) exiting the cylinder is controlled by the adjustable retarder blade (I).

Choice of Various Flow Options to Suit All Separation Requirements
Parallel flow is characterized by the same product flow directions for each cylinder row. From a main spout, the product is equally distributed to cylinder rows from one side of the machine.
Series flow allows for multi-separation from one stream and is characterized by the counter-flow directions of the separated product for each cylinder row. The product enters the first cylinder row and flows back through the row below.
Parallel and Series Flows May Be Combined in One Machine
