Abstract
Reinforcement sections are provided at an outer surface and at an inner surface of a tire for a roll wheel assembly used in a pulverizer for crushing a material such as coal. These reinforcing sections cause the tire to be asymmetrical and are located on the tire only at areas where the wearing of the tire is highly predictable. The reinforcing sections provided on the inner surfaces of the tire are provided directly opposite of the reinforcing sections on the outer surface for preventing the localized thinning of the tire and extending the time interval between rotation and/or replacement of the tires.
Claims14
A tire for a roll wheel assembly used to crush material in a pulverizer, the tire having an asymmetrical outside diameter outer surface for contacting and crushing the material, the tire comprising:
- a first reinforcing section fixed to the outer surface of the tire to provide the asymmetrical outside diameter outer surface at a location where the tire is subjected to wearing due to performing the crushing of the material;
- and
- a second reinforcing section fixed to an inner surface of the tire directly opposite of the location where the tire is subjected to wearing for minimizing localized thinning of the tire.
A method for prolonging the use of a tire of a roll wheel assembly for a pulverizer used for contacting and crushing a material, the method comprising:
- providing a reinforcing section on an outer surface of the tire to provide an asymmetrical outside diameter outer surface on the tire at a location where the tire is subjected to wearing due to performing the crushing of the material;
- and
- providing a reinforcing section on an inner surface of the tire directly opposite of the location where the tire is subjected to wearing for minimizing localized thinning of the tire.
