What design features prevent clogging and uneven spray in emulsion bitumen sprayers?

Effective filtration stages, stable pressure regulation, correct nozzle sizing, and a recirculation loop are essential. Spray bars should have uniform nozzle spacing and easy access for cleaning. Materials must resist corrosion from acidic emulsions. A calibrated flow meter and speed linked dosing help maintain constant application rate. Temperature management matters because cold emulsion becomes viscous and clogs, while excessive heat can trigger breaking inside the line.
