Abstract
A system and method for tennis ball recycling that processes tennis balls into one or more constituent components to generate useful products is disclosed. The system includes a hopper to hold the balls for recycling; a grinder having a plurality of blades to initially cut the tennis balls in a first step to separate the rubber from the nylon; a cyclonic extractor that further separates loose fibers out in a second step; a trommel separator that further filters the broken down components of the tennis balls for use in new products.
Claims20
A tennis ball recycling system for use with a plurality of tennis balls comprising rubber and nylon, the system comprising:
- a hopper configured and dimensioned to hold the plurality of tennis balls;
- a grinder including a housing supporting a shaft and a plurality of blades secured to the shaft, the plurality of blades being substantially y-shaped with a forked member at a first end of the blades and a cutting member at a second end of the blades;
- a motor operatively connected to the shaft;
- a first feeder auger configured to supply the tennis balls to be recycled from the hopper to the grinder, wherein the plurality of tennis balls are deconstructed by the plurality of blades which are constructed and arranged to cut into and separate the nylon in the tennis balls from the rubber of the tennis balls creating broken down components;
- a cyclonic extractor including an inlet to receive the broken down components of the tennis balls from the grinder, a tapered body and an outlet;
- a trammel separator including an inlet to receive the broken down components of the tennis balls from the cyclonic extractor, a rotary drum, one or more screens to further filter the broken down components of the tennis balls, and an exit channel;
- a second feeder auger configured to move the broken down components from the cyclonic extractor to the trammel separator;
- an airlock disposed between the cyclonic extractor and the trammel separator configured to minimize air loss while transferring the broken down components of the tennis balls from the cyclonic extractor to the trammel separator;
- and
- wherein during use further separation is done by the cyclonic extractor, which separates loose fibers from other broken down components of the tennis balls, and even further separation is done by the trammel separator, such that broken down rubber and nylon, from the broken down components, exits through the exit channel of the trammel separator and is suitable for use in new products.

A tennis ball recycling system comprising:
- a hopper configured and dimensioned to hold a plurality of tennis balls comprising nylon and rubber;
- a grinder including a housing supporting a shaft and a plurality of blades secured to the shaft, the plurality of blades including a forked member at a first end and a cutting member at a second end, opposite the first end;
- a motor operatively connected to the shaft;
- a first feeder auger configured to supply the tennis balls to be recycled from the hopper to the grinder, wherein upon entering the grinder the plurality of blades cut into the tennis balls creating broken down components;
- a cyclonic extractor including an inlet to receive the broken down components of the tennis balls from the grinder, a tapered body and an outlet;
- a second feeder auger configured to move the broken down components from the cyclonic extractor to the trammel separator;
- a trammel separator including an inlet to receive the broken down components of the tennis balls from the cyclonic extractor, a rotary drum, and an exit channel, the trammel separator being operatively connected to a vibration filter including a progressive filtration system to clean the broken down tennis ball components;
- and
- wherein broken down rubber and nylon, from the broken down components, exits through the exit channel of the trammel separator and is composed substantially of nylon.
