Rubber or polymer bales enter the feed hopper, typically by gravity from a feed conveyor. Slow rotating claw-like hammers cut into the bales, shearing them into smaller chunks. Internal adjustable anvils, or resistor bars, provide internal resistance to better control energy input which determines heat input and final particle size. The ground material continues forward to the discharge where it is forced through an orifice plate. Upon exiting, the extruded rubber is sheared by the cutoff knife assembly, producing a consistently sized granule, or crumb size. This rubber crumb often discharges by gravity directly into a dissolution tank.
Depending on the material being processed, or the downstream operations, Bepex has provided dosing equipment to meter in anti-sticking agents such as talc either in the grinding chamber or at the discharge. A specially designed hydraulic ram feeder may sometimes be necessary to force-feed bales into the grinding rotor.
The Rubber Chopper bale grinder is just one of the size reduction technologies we employ to develop industrial process systems that meet your application requirements. At Bepex, we are committed to developing the best size reduction process systems using the right technology. Between our proven industrial process equipment and decades of experience serving the industry, we are able to design a grinding solution that is right for you.
