Production of Rubber Flooring From Recycled Tires
The tires are recycled for use as flooring at a specialist plant, where they undergo shredding and grinding into small particles known as rubber crumb. This crumb can either be bagged and dispatched to another company specializing in rubber processing or they can be processed onsite.
We shall presume the rubber crumb is to be processed onsite as part of the recycling process and a overview of the process from receiving the tires to the end product follows.
The tires are fed whole onto a manually or automated shredding machine which tears the tires into more usable pieces, which are conveyed to a rotating cutter machine.
From here, the rubber pieces are transferred to a granulator that grinds them into rubber crumb. These are then conveyed under an electromagnet, removing the pieces of steel reinforcing wire. The crumb is then passed through a set of screens which graduates them into different sizes, while air is injected removing the lighter nylon and small fluff pieces.
The crumb is then ready for melting. This is achieved by heating crumb in a steel cauldron, the heat being applied to the outside of the cauldron. This liquid rubber can then be poured into non-stick containers and allowed to cool, ready for reheating and laying as a rubber floor in a residential property.
