Abstract

PURPOSE: To remove unmixed dust by providing an air vent in a dry spray apparatus in which water is added immediately before spraying to compounding materials such as cement, sand etc. which are pressure transferred.
CONSTITUTION: Compounding materials A mixed by a rotor 3 are sent to a tapered tube 16, and the materials are transferred to distant work site through pressure transfer hoses 18, 21 by compressed air from an inlet tube 26. At this time, water is injected to the materials A from an inlet tube 21' through a watering device 20 and the materials A are mixed with water during transfer thereafter, and sprayed to the objective working part from a nozzle 24 at the tip. An air vent 22 is provided at the tip of the pressure transfer hose 21 and dust not yet mixed is removed from the vent 22.
