ABSTRACT:
A refiner that reduces solid material to a particulate form includes a rotatable sidewall, a bottom, at least one exit hole, and a rotatable toothed disk. One or more baffles may be attached to the chamber sidewall to form one or more surfaces that extend into the chamber. The baffles help move the solid material toward the rotating toothed disk. The baffles also limit material from being inadvertently thrown out of the chamber. A moveable gate may be positioned to change the size of the exit hole and thus regulate the size of particulate material exiting the chamber. The position of the gate may be adjusted during the operation of the refiner chamber. A gate indicator indicates the relative position of the particle size gate. One or more attachments to the bottom of the chamber may be used to limit the amount and/or size of material engaging the toothed disk.
