This machine is a steel sand blasting machine, which consists of blasting chamber, Blasting wheel assembly, Roller conveoyr, Abrasive recycling system (Screw conveyor, Elevator, Separator), Dust removal system, Electric control system, etc.
1.Blasting chamber
Shot blasting chamber shells adopt profile steel and steel plate welding structure, is a strong, sealing, spacious operation space for shot blasting of workpieces. Shot blasting chamber is made by room body shell, gate, wall around, lateral wall, roof after, guard board etc.
2.Blast wheel assembly
Blast wheel assembly is made up of blast wheel shell, motor, importing tube, leaf, impeller, directional set of pills, points wheel, block sand plate, guard board and other components, which leaves, guard board, etc all wear parts using 20% high-chromium cast iron.
3.Screw conveyor
The screws convey or consist of reducer, screw shaft, conveying Housing, rolling bearing with bases, etc. It is a kinds of standard abrasive/sand horizontal conveying device, is an important part of the abrasive recycling system of the blasting machine.
4.Bucket elevator
The bucket elevator consists of speed reducer, upper and lower rolling barrel, transmission rubber belt, bucket elevator, enclosure and tightening device, etc.
5.Separator
This machine adopts advanced Model BE full shutter type separator. The separator is mainly composed of airwash area, barrel sift, conveying screw, abrasive hopper, manual abrasive controlling valve.
6.Dust removal system
This machine adopts Cartridge or Bag type dust collector, is exhausted air produced during working. The dedusting efficiency is up to 99.6%, powder density is less than 100mg/m`3,much stricter than the national standard.
7.Electric control system
Set shot ball circulatory failure alarm function, if any parts of the system fails, the above components automatically stop running, to prevent the shot ball stuck and burning power device.
