Differences between curb extruder and slipform curb paver?

Curb extruder and slipform curb paver both for road curb construction.

The main diferences:

1. Working theory: Curb extruding machine using auger blades to squeezing concrete or asphalt forming curbstone.Slipform curb paver using vibrator to form concrete kerbs.
2. Moving type: Extruding type is moving by the backforce of curb.Slipform kerb machine is automatic self moving.It has a moving power and moving system.
3. Workable material: Curb extruding paver can produce asphalt kerb or concrete curb.Slipform machine can only produce concrete curbstone.
4. Concrete slump：kerb extruder use lower concrete slump.kerb slipform paver use higher concrete slump.
5. Working speed: slipform type curb machine is faster than extruder curb paver.
