Continuous rocker barrel shot blasting machines are designed for big amount high performance cleaning. The work-pieces keep mixing and rolling while blasting for a high coverage. The rocking frequency, barrel tilt angle and abrasive amount are all determined by types of work-pieces. It is easy to integrate with other automatic production lines.
Production speed: 5 tons/hour to 25 tons/hour, available for work-pieces with different dimensions, weight an sensitiveness by customizing rocking frequency, barrel tilt angle and abrasive amount.
Multi-level reclaiming system can achieve a abrasive-contaminant separation effect up to 99%, primary and secondary magnet separators are available.
Key feature of overhead rail shot blasting machine
☆Dynamic Simulation Design
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.
☆The blasting chamber is composed by structural profiles and all necessary components.
☆It is welded by steel pate and profiles which to ensure the rigidity and strength of the blasting chamber, the access door is greatly convenient for the machine maintenance and inspection
☆Shot blast cabinet is constructed of 12 mm high manganese steel plate with heavy structural reinforcement, the lifespan is more than 6 years
☆4-8 blast turbines are arranged reasonably at the top to ensure the best projectile ejection Angle, so as to thoroughly clean the workpiece.
Rocker barrel system
Adjustable imbalance weight units equally distributed over the entire length of the processing bowl.
The polygon shaped rocker barrel has hump on inner surface to gently tumble the work-pieces.
Rocking angle of whole barrel system is 120°, tilt angle is adjustable according to work-pieces.
The rocker barrel is protected by 20mm thick Mn13 steel plate.
The drainage holes at the bottom of the inner are helpful for the discharge and recovery of abrasive.
Max 3-grade dust collecting design can achieve max 99% clean efficiency.
☆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 arveage 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%.
