Functions and operations of the Separator
Exercise extreme caution when performing any
adjustments to the machine.
The unit consists of:
1. 4 or more Spiral Shafts (variable speed)
2. 4 or more Clod Roller shafts (variable speed)
3. Spring tension adjustment for the clod rollers
4. Clod roller height adjustment
5. Clod roller gap adjustment
1. Spiral Shaft
The spiral shafts consist of up to 14, 6 fluted spiral segments per shaft. The spiral shafts
are fixed in position and cannot be moved.
In order to remove a spiral shaft (for replacement of spiral segments), there is a plate
bolted to the main side panel which when removed, allows the shaft to be drawn straight
out of the side.
Chain adjustment for the transfer roller drive is
not
necessary as this operation is
performed by the self-adjusting chain tensioner which should be set pre-tensioned.
2. Clod Rollers
The clod rollers are held in position by a hanger which is fixed to the up/ down
adjustment profile using a circlip. The clod rollers are adjustable up and down as well as
left to right in order to increase/ decrease to gap between spiral and clod roller to
achieve more/ less separation.
There is a scraper positioned under each clod roller to keep the roller free from soil etc.
sticking to it. It is important that these scrapers are correctly adjusted with a minimum
gap of 3 mm.
Direction of rotation is an important factor. The unit is supplied with the option of running
the clod roller in either direction .If the direction of the clod roller is needed to be
changed for any reason we strongly recommend the scrapers are turned around at reset
to their 3mm gap for correct scraping of the roller. Warranty claims will not be upheld if
the scrapers are not correctly fitted for their use.
3. Spring tension adjustment for the clod rollers
Clod rollers should not “spring away” excessively only to allow larger particles to pass
through such as stones 1” or greater. Spring tension is usually set at the factory but if
more tension is required or if springs are replaced etc the tension on each spring can be
adjusted by the M12 studs located below each clod roller. First loosen the locking nut
then adjust with a 19mm spanner to the required position, you may find that this will alter
