How rolley conveyor automatic sandblasting machine works?

During the cleaning process, the electrically controlled conveying roller conveys the steel beam into the blast working room, and all sides of its body are hit and cleaned by abrasives from different coordinate positions, making the upper part of the oxide scale, rust layer and its dirt quickly fall off, and the surface of the steel has a certain smooth surface and hardness, which improves the adhesion of the paint film, and improves the internal quality of the steel, and prolongs its service life.

Automatic Conveyor Sandblasting Machine Features:

automatic sandblasting gun

Automatic Blast Guns

Workparts are conveyed to the sandblasting area where they are processed by a group of automatic guns. Each blast gun is individually controlled for working by demands. Depending on the parts' shapes and dimensions, the automatic sandblast guns can be set for fixed blasting or oscillating blasting with adjustable angles. The gun nozzle is made of durable borron carbide material.

Continuous Rollery Conveyor

The conveyor motor is controlled by frequency converter, whose speed can be steplessly regulated by inverter within the range of 0 ~ 2m/min. Several types of conveyor belt are available to move your parts through the blasting area, such as stainless steel belt, rubber belt, or roller conveyor. The rubber type belt is wear-resistant and corrosion resistant.


PLC Control with Touching Screen

The sandblaster applies advanced PLC electric control system, with a high degree of flexibility and stability. The touching screen offers user-friendly interface to manage the blast working, adjust conveyor speed or start the dust collector. High automation guarantees the balanced uniform blasting effect, as well as safe production

Dust Removing & Media Recycling

Designed with cyclone separator for effectively separation of abrasives from dusts. Along with an independent cartridge filter dust removal system with excellent effect of dust extraction and ventilation,  Blast-removed dust particles are exhausted to the dust collector while blast media is collected at the bottom of the cabinet, then returned to the storage hopper for further use.
