The new NS-SC Seed Cleaner is designed and manufactured by Crippen Northland Superior for accurate separation of any commodity on the basis of length difference.

The modular design allows the NS-SC to be used individually or arranged as a multiple cylinder machine. A variety of interconnecting spouting arrangements provide for a wide range of flows.

The NS-SC separator is a simple, single cylinder machine utilizing a main drive, conveyor shaft, and cylinder as the only moving parts. A 17" diameter cylinder, hardened for optimum life, is the primary component of the NS-SC. The size of the indent pockets on the inside surface of the cylinder determines the length of the lifted material. Any material the same size as, or smaller than the indent pockets is lifted and dropped into the receiving trough. The transportation of the material from the trough to an outside spout is performed by a screw conveyor. The remaining larger material is taken to the discharge spout by grain line blades connected to the outside bottom of the trough.

A 1/2 H.P., 1800 RPM motor mounted inside the body of the machine allows variable speed through a V-belt drive and reducer.

Great Flexibility
Indent cylinders are available in many sizes to suit a wide variety of separation needs. Variation in separating performance can be achieved by several easy adjustments.

cylinder speeds variable from 35 to 60 RPM
wide range of trough angles
retarder control for grain depth

All controls are within easy reach of the operator.

Easy Cylinder Change and Cleaning

The NS-SC separator is easily and quickly cleaned.

machine can be mounted on a slight incline to allow faster cleaning
removable doors give easy access to the cylinder compartment for easy cleaning and maintenance
optional split cylinder construction allows fast replacement of cylinder

Easy Operation and Maintenance
Simple construction, smooth, vibration-free operation are factors making the NS-SC separator very efficient in all aspects of operation and maintenance. The NS-SC separator is solidly constructed and only routine maintenance is required to ensure years of trouble-free operation.

Crippen Northland Superior's advanced surface hardening process ensures the cylinders are both long lasting and round.
The universal design of Crippen Northland Superior's cylinders enable them to be used on other manufacturers' 17" cylinder machines.

A wide range of simple operating adjustments allows for variation in the product to be separated. The separating edge (A) can be raised or lowered, so the receiving trough (B) catches desired liftings as they drop free from the indents in the cylinder (C). This adjustment can be set by turning the handwheel (D) which causes the pointer (E) on the indicator dial (F) to be moved. To build up and maintain the desired grain level, the retarder can be positioned by using the counter weight (G). The inspection opening (H) allows observation of the separation process taking place inside the cylinder. If necessary, the cylinder speed can be regulated during operation by turning the handwheel (I).
