Mortar Rotary Sprayer

Mortar Rotary sprayer has a rotary spraying part inside. It works as a special terminal tool for trenchless lining repair. People use it to spray polymer mortar and polyurea coating inside drainage pipes and inspection wells. It runs automatic continuous rotary spraying. It takes the place of manual painting work done underground. Construction quality and safety for trenchless repair become much better.

People made this Mortar Rotary sprayer fit tough conditions in trenchless repair work. Its whole structure can resist corrosion. It stands long‑time damage from high‑alkaline repair mortar. Key rotating parts are sealed well to keep water out. Mortar slurry cannot get inside and jam the machine. It works steadily even when put under water. It suits drainage pipe networks which often hold water during work.

We change spraying pressure and rotating speed with upper‑level equipment. Workers adjust construction parameters based on needed lining thickness and different kinds of slurry. Coating thickness error stays inside the allowed range of engineering projects. No materials are wasted, and the lining will not be too thin or too thick. Its nozzles can be taken off and changed. We use nozzles of different sizes for repair materials with different thickness. It works for polymer mortar, polyurea coatings and other repair materials, so it can be used in many situations.
