Continuous Rocker Barrel machine is designed for high-performance in-line cleaning of castings and forged parts. To satisfy production requirements ranging from 5 tons/hr to 25 tons/hr, a variety of machine sizes are available with blast capacities selected to match the specific cleaning requirements. Flexible systems can quickly adapt to changes in production rates, lot size, finishing techniques and market demands. There is practically no limit regarding parts size and shape and parts geometry.

Blast chamber

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.

Conveyor system

※Powerful vibratory drive.
※Adjustable imbalance weight units equally distributed over the entire length of  the  processing bowl.
※There is a steel mesh on the conveyor to screen out impurities.

Rocker barrel system

The rocker barrel is polygon shaped, there are a lot of hump in it and forth to gently tumble the workpieces. The drive that rocks the barrel is controlled from a touch screen on the operator panel. An adjustable range of rocking motion(120°) ensures different shaped castings can be tumbled satisfactorily.
※ The rocker barrel use thickness 20mm Mn13 steel plate, the lifespan is more than 8 years.
※The perforation at the bottom of the inner lining is helpful for the discharge and recovery of pellets. It doesn’t block

Blast turbines

※impeller adopted#40 Chrome wear resistant cast iron, HRC≧60-65
※High chrome wear resistant cast iron for blades, control cage, abrasive distributor, Gr≧20%.
※The blade is a curved blade, which can get a higher projective speed under the same impeller speed.


Greatly reduced work force- for fettling, no workers are required to transport castings
Comfortable and safe working conditions- Gat cutting performed after blasting is more comfortable; No more hot and dusty work conditions
Saves floor space- compact layout is possible requiring only about half the floor space of an equiivalent batch type machine.
Reduced lead time- continuous blasting minimizes time loss.
Recovery of moulding and core sand during shot blasting by means of magnetic separator
Minimal pollution through complete control and capture of dust throughout the production line right from punchou.
