Blocked Rondo hose

Has anyone got any ideas on how to unblock a 25mm material hose on the ritmo? I can get water and the cleaning ball through but the render gets clogged and jams the machine
 
on the screed pumps, when the hose got blocked and the material had set. we would lay the tube on an area of concrete and run the lorry along the tube.
if the material was still wet in the tube ,we would remove the tube hang it up the scaffolding and run the hose through it until it was clear.

It can't be a proper blockage if the Ball still comes through,
The inner wall must be caked up a bit with render sucking the moisture out of the new gear as it comes down the tube,
Block the one end and poor diluted brick acid down and leave it overnight,
Before you use in future stick some diluted wallpaper paste down the tube.
 
on the screed pumps we pour diesel down the tube to lubricate it before we start.

I think you’re right, driving me insane. I’ll get the acid on it, how do it put the paste in? Just gravity feed from hanging the hose?

I just knock up a sachet of wallpaper paste with a gallon of water put it in an old PVA tub and before a spray tip a couple of litres down the house and lift the hose until it comes out the other side into a bucket and then you can keep it for the next time
 
Could buy a new one too mate I blocked my original one up in summer and just left it on the job was sick of trying to clear it

I've got them years of age if you clean it out to all be fine and handy to have spare one's
 
The first time u use it after u unblock it. Wet the hose put some wallpaper paste in the end of the hose that connects to the machine. Let the render push the wallpaper paste trough the hose
