Abstract: A method and apparatus for creating a uniform texture on the face of an object using at least one sandblasting nozzle. Each nozzle is disposed at a placement distance from the face of the object based on factors including the relative motion therebetween, the size of the nozzle, the air pressure feeding particle through the discharge end of the nozzle, the material composition of the object, and the desired appearance of the face of the object after texturizing. The nozzle discharges blast media to uniformly texturize the face of the object to obtain the desired appearance.

Abstract: The present invention is directed to a sandblasting unit for testurizing objects, and a method of using the unit. The sandblasting unit includes a frame and a housing, with a sandblasting nozzle positioned within the housing. A conveyor belt moves the objects, such as concrete blocks, through the housing for treatment or testurizing by the sandblasting particles. The nozzle emits a spray of sandblasting particles which disperse to cover an enlarged area, with a concentration of particles in a central locale within the coverage area. A protective baffle plate blocks the spray in the central locale so as to eliminate the concentration of spray therein and thereby produce a uniform texturized surface on the object. The baffle plate is adjustably mounted within the housing so that the desired uniformity of texturizing can be achieved. The unit also includes a collection funnel for collecting the used sandblasting particles and vents for suctioning away the waste material sandblasted from the object.
