Abstract
The present disclosure relates to a pulverizer includes a pulverizer housing with an grinding assembly having a grinding table situated therein. The grinding table provides a grinding surface area for a material, such as a fossil fuel, such as coal, to be pulverized. The grinding table is mounted on a gearbox shaft operatively connected to a gearbox drive mechanism so as to be capable of driven rotation within the pulverizer housing. A journal assembly having a journal head and the journal assembly and a spring assembly are mounted on the pulverizer housing so that the journal head engage the spring assembly.
Claims7
A pulverizer for pulverizing a fuel, comprising:
- a grinding assembly including a grinding table which provides a grinding surface area;
- at least one journal assembly including a journal head having a first end connected to a journal shaft that rotatably supports a least one grinding roll, the journal assembly configured to transmit a force through the journal head and the journal shaft to the at least one grinding roll which rotates on the grinding surface area due to rotational force provided by the grinding table, the journal head is pivotally mounted on a pair of pivot shafts to pivot the at least one journal assembly towards the grinding surface area;
- and
- at least one spring assembly including a spring in a spring housing, the at least one spring assembly arranged to engage the journal head at a second end of the journal head distal from the first end to provide support and a force via the spring for the pulverization of the fuel to the journal assembly through the journal head.
