The through-feed blast cleaning process offers a number of distinct advantages and ensures efficient and cost effective blast cleaning. Continuous shot blast machines automate production sequences and improve the work environment.Workpiece dwell-time and abrasive throughput rates are controlled by the volume of castings. This results in the best possible cleaning effect and minimal wear on machine components and abrasive. Automatic adaptation to production rate is a standard feature.

Blasting chamber
1.The blasting chamber internal liner use thickness 12mm high manganese steel plate, the lifespan is more than 8 years(based on turbine working time 8 hrs/day, 6 days/week). 2.There are multi-layers of temperature proof and abrasion proof rubber curtain, which prevent the abrasive escaped from the blasting chamber to maximum. 3.There are equipped with 4 units of high performance blasting turbines in the optimized reasonable layout position, which guarantee the completely blast cleaning the workpieces in the shortest time. 4.Inclined angle of the tumblast belt: this design is determined by the blast processing quantity of workpiece, shape of workpieces and the production capacity requirements, the metal tumblast belt always installed at an angle inside the blasting chamber, which is to ensure the best blasting effect and the minimum consumption of the blasting media and abrasion parts of the equipment.
Tumble system
4.The belt is composed by thickness of 20mm high manganese plate, the holes on the belt are cutted by water jet cutter in order to prevent the deformation, the chain ring adopted a unique structure so as to let the spattered blasting media drop into the abrasive reclaim system. The tumble belt rolling drum liner adopt high manganese steel plate, the rotation of the drum use the heavy-duty bearings to ensure the stability and durability of usage. The holes on the drum are cutted by water jet cutter in order to convenient the abrasive reclaim.
Loading and unloading of workpieces
3.It is aimed for the conveying of the workpieces and separating the big contaminants from the workpieces
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.
Abrasive cleaner
Our patented abrasive cleaner is applied for recycling shot/grit, which is to ensures high quality blasted surface and munimal abrasive shot. As the abrasive is so durable it is able to be recycled hundreds of times, resulting in an extremely low abrasive breakdwon rate.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.
