Key feature of Paver Block Shot Blasting Machine

Blast Turbine

☆Dynamic Simulation Designblast wheel 2
The liners form a round track for abrasive, which allows all abrasive leave the turbine when they reach the highest speed with the least internal bounce and self-wear. Can offer high blast speed and full abrasive cover.
The maximum thickness of blast wheel shell can reach 70mm, better sealing effect, long service time.
The interior of the blasting wheel is turbo type, abrasive will not not stay in the distributor. Abrasive utilization rate increased to 99%, improve efficiency by 30%.
Blast wheel bottom has cushioning rubber, which can reduce vibration.
☆Blade & Impeller
The material of impeller is 40CrMnMo, the material of blade is high chorme wear-resistant casting iron, the hradness can reach HRC60-65.


Blast chamber

Blasting chamber -- beams shot blasting machine 11☆ Working principle
The engineering team uses 3-D dynamic simulation design blast turbines layout to ensure that the steel shot ray can cover the surface of the workpiece 360 degrees.
☆10 Years Warranty
Shot blasting chamber with Mn13 steel guard plate which has high impact toughness and high service life, fully realize the reflection funcation of abrasive and improve the cleaning quality.
That we promise 10 years maintenance-free warranty to blasting chamber.
☆High sealing performance
3+ layers of sealing curtain in inlet, outlet opening and between chambers. The curtain layers are natural rubber material with leaf spring which can automaticlly reset,
that prevent the abrasive spatter out duing the blasting and ensure the safe.


Abrasive Cleaning Up System

abrasive cleaning up system 1Including: brush, screw conveyor, abrasive blowing fan and lifting mechanism.
The material of brush is high strength MC nylon, it can use about 5 years.
The nozzles are adjustable in height and therefore adaptable for the treatment of different height steel plate.
After abrasive cleaning up system working, the surface of steel plate no any steel shot and dust.


Dust collector

Max 3-grade dust collecting design can achieve max 99% clean efficiency.dust collector 232

☆Level-1 Dust Collecting: a gravity settling box above inlet/outlet chamber will make the abrasive shot in airflow drop back to chamber, so the dust collecting filter will not be damaged by abrasive shot, can achieve a longer service time.
☆Level-2 Dust Collecting: Cyclone dust collector have 2 collection points for dust and debris, primary collection point is for heavier chips and debris, while the second point is for finer particulate matter. 
☆Level-3 Dust Collecting: high filtering avreage cartridge type or venturi design bag type filter can offer a long service time high filter ability effect, the final cleaning efficiency is upto 99%.
