Roller Conveyor Shot Blasting Machines
Technical Support1．Blast wheel layout adopt 3-D dynamic simulation design, ensures optimal shot blasting angle and distance, treat the object items on all sides with a high quality surface appearance but without overlapped and dead zone.
2．The equipment designed was fitted with our heavy-duty blast wheel system, which generates significant operating cost reductions due to faster through put times, as well as reductions in shot-blasting media consumption and energy requirements.
3．The blast wheel of the machine are equipped with shielding facility to lower the noise level.
4．The equipment adopt pneumatic control abrasive distribution system, which eliminate the blast wheel idling and injuring workers
5．The equipment is equipped with adequate safety interlock device, which meet European safety standard.
6．The machine adopt environment friendly high efficiency cartridge filter, dust collecting efficiency reach to 99.9%
7．All the abrasive recycle system automatic fault detection
8．The equipment adopt labyrinth sealing mechanism at the enter and exit gate.
9．The blasting cabinet of roller conveyor shot blasting machine adopt 8mm steel plate welding together, which have high strength and will not generate vibration during working. The guard plate of the blasting cabinet adopt 12mm high manganese steel plate which prolong the blasting chamber lifespan.
10．Pneumatic swing-rotating sealing mechanism for H beam effectively prevent the abrasive spilling out.

Blast cabinet• Welded by steel plates and profile steel, have enough strength and rigidity.
• ZGMn13 steel guard plate, which is hard enough to deal with the shot blasting from 35HRC to more than 55HRC.
• High impact toughness can make full use of the reflection kinetic energy of shot to continue to blast cleaning the surface of work piece, so greatly enhance the cleaning efficiency and quality.
• High chrome wear resistant cast iron grate guard plate which protect the screw conveyor and prevent big clump to get into the hopper damaging the bottom screw conveyor
Blast turbines• Cantilever centrifugal high efficiency blast wheel, can operate clockwise or counter-clockwise, optimum abrasive flow rate for faster cleaning.
• impeller adopted #40 Chrome wear resistant cast iron.
• High chrome wear resistant cast iron for blades, control cage, abrasive distributor.
• Dynamic and static balance.
• Blades of impeller weight tolerance≤±1.5g.
• Unbalanced torque tolerance≤±7.5Nmm.
• Direct drive blast wheel with special motor bearings means less spare parts, less noise, energy-efficient, large abrasive flow rate and good cleaning effect ,etc. advantages.
• Machined housing ensures proper alignment of all internal parts.
• Less part wear due to greater concentricity and more precise alignment.
• Safety interlock is fitted on the housing cover to protect the workers safety.
• Particular guard liner structure increase the abrasion resistant lifespan 60% to 200%.
Pneumatic Abrasive dosing units• Patented pneumatic control abrasive gate valve, which depend on cylinder to control stroke so as to control the blast wheel in long-distance. This avoids motor burned, blast wheel jammed, shot idling blast and people injured caused by common abrasive control valve closure lax
• Abrasive flow is indicated at the ammeter at the electrical switch and control box.
• Adjusting the bolt on the abrasive control valve can conveniently adjust the abrasive flow rate to an required amount
• In order to be able to dismount the abrasive control unit from the silo for repair works and to avoid any abrasive outflow for each unit one manual slide is installed in front of the abrasive control unit.
Critical to achieving this efficiency is the effectiveness of the abrasive recycling plant. Poorly designed or manufactured abrasive recycling systems will not correctly recycle the abrasive and are unable to maintain the correct abrasive working mix.
Our patented abrasive separator consists of an extended rotary separator drum that will totally remove all big clumps including big wast, scrap and paint chips etc. The abrasive is then fed through a gravity air wash separator where all dust, degraded abrasive and waste is drawn out of hte good abrasive by an air current.
Only good, correctly sized abrasive is fed back to the abrasive storage hopper and blast pots for recycling.
Our patented abrasive cleaner ensures maximum recyling rates of the abrasive and high quality surface finishing is achieved.
