ABSTRACT:
An apparatus of this invention for dispensing particles into an annular pattern is preferably employed in relining a foundry furnace. The furnace relining operation comprises positioning an expendable steel form in the furnace spaced apart from an outer wall, filling the annular space with refractory particles, and sintering the particles into a continuous lining. The apparatus of this invention comprises a platform removably positioned atop the form and having a circular track. The apparatus further comprises a carriage rotatably mounted on the platform and riding on wheels that travel along the circular track. A supply of the refractory particles is loaded into a hopper carried by the carriage. A feeder conveys particles from the hopper for discharge into the space. During use, the carriage rotates while continuously dispensing particles to uniformly distribute the particles into the space. After filling, the apparatus is removed from the form, whereafter the refractory particles are sintered into a continuous lining.
