Canning operations worldwide create large quantities of unsaleable canned products that have been rejected due to container damage, processing problems, or out of date stock. While not suitable for human consumption, this resource is perfectly suited for livestock and can be mixed with standard animal fodder to create a high value fodder with high moisture content.
The problem has been how to remove the can contents efficiently without contaminating the end product with steel as even the smallest piece of steel that finds its way into animal fodder will seriously injure or kill the animal.
Brentwood has combined several of our technologies to arrive at a solution that recovers 95% of the can contents with zero steel contamination AND cleans the steel cans ready for sale as clean steel scrap.
The plant accepts material loaded into the in-feed hopper and transfers this a feed conveyor that send the material to a Brentwood AZ50HD shredder where the steel cans are shredded, releasing most of the contents.
The shredded material is fed through a specially designed screw feeder equipped with high pressure water sprays allow any remaining solids to be released from the cans. A series of magnetic separation systems ensure that the solids are steel free and these are discharged into a suitable container.
The steel content is further processed to separate any paper or plastics that have been released so that clean steel is sent to the steel discharge conveyor. The system also removes non-ferrous materials, plastic and paper from the steel and solids stream and these are diverted to a separate collection bin.
