If its the same as the one on the trucks, we call them spinners, they are turned by oil pressure.
On the bottom of the inner unit are two jets which spray oil at pressure against the side of the outer casing like two little thrusters, the inner unit which holds these jets sits on a spindle which is fed oil from the pump, the oil drains off from the bottom of the unit back to the sump. You open up the unit scrape off the caked oil, clean with parafin and then rebuild with new o rings. Great idea.

On the Disco TD5 there is a fork arrangement that the rotor filter bottom sits on and that's what spins the filter.

No there isn't. David sort of got it bang on, except no cleaning involved in these as you just remove the old casing and replace.
The oil is fed up the shaft in the middle, which the filter sits on, there are two small holes at the bottom which the oil sprays out of and pushes the filter body around, and this spinning force creates a centrifuge which throws all the carbon and other deposits out onto the ridged walls of the filter body.

That was after about 18,000 miles I think. CharlesY will confirm.
The LR service interval (not sure what it says) is probably adequate, however I always change oils and filters before the due mileage anyway for the sake of 2 bolts and a fiver every now and again it's not a big deal.

'Fraid not ...
the rotor fits on hollow spindle and sits on a flat washer. Oil comes into the rotor through the spindle at high pressure, and fills it up. On the bottom of the rotor are two little holes pointing tangentially, so that when oils spurts out of them the rotor starts to spin. Like it spins VERY fast, like 12,000 rpm and more. The crap in the oil gets thrown to the inside wall of the rotor, and sticks there, building up to caked crap.
It works quite well. I sawed my last one open a week ago.
I run my TD5 Disco on Tractor Universal Oil all the time, and change the oil and the flilter and the rotor regularly HA HA, somewhere between every 7 and 10 thousand miles.
Twenty pounds easily covers the oil, a good filter and a rotor.

Hi Charles, obviously my descriptive powers were not at their best when I posted my comment.
I just couldn't think of a better way of illustrating it - but you did, so well done.
Sometimes TD5 owners can hear their rotor spinning down after they stop the engine.
If the engine and the oil are good and hot it may take several minutes for the rotor to stop turning.
These filters are particulary good at taking heavy particles out of the oil. Clean oil is good for engines.
