Cutting and grinding of ceramic-type logs to a desired piece length is disclosed. A method of manufacturing ceramic ware is disclosed which comprises transversely cutting a piece from a ceramic-type log having a longitudinal axis by cutting into the log with a blade at a location along the length of the log to form a cut transverse surface on the piece and grinding the cut transverse surface with a side of the blade. An apparatus for manufacturing ceramic ware is also disclosed comprising means for transversely cutting a piece from a ceramic-type log having a longitudinal axis, including a blade for cutting into the log at a location along the length of the log to form a cut transverse surface on the piece, and means for grinding the cut transverse surface with a side of the blade.

Methods of extruding a honeycomb body with an extruder comprise the step of feeding batch material to the extruder, wherein the batch material comprises a ceramic or ceramic-forming material. The methods further include the step of rotating at least one mixing screw to cause the batch material to travel along a flow path defined by a barrel of the extruder. The methods further include the step of indexing a carriage to remove a first device from the flow path and introduce a second device into the flow path of the batch material. In one example, the pressure of the batch material changes less than about 25% as a result of indexing the carriage. In addition or alternatively, further methods include the step of reducing a decrease in temperature of the batch material resulting from the step of indexing. In further examples, the method includes the step of pre-filling a second honeycomb extrusion die held by the carriage with a plugging material.

Methods and apparatus for testing the strength of ceramic honeycomb structures are described. The apparatus includes a chamber that utilizes a flexible, generally cylindrical member including integral flanges to apply compressive force to the periphery of the honeycomb structure. According to some embodiments, a portable apparatus with an open chamber is provided to allow for rapid testing of multiple honeycomb structures.

Ceramic honeycomb strength testing apparatus

The invention is directed at an apparatus capable of the continuous drying of ceramic articles which produces little or no microwave radiation emission. The drying apparatus comprises comprise a microwave-heating chamber, for heating a ceramic, having an entrance and an exit end and a material flow axis along which the ceramic articles are conveyed. Positioned adjacent the entrance and exit ends of the microwave-heating chamber, respectively, are a first and second attenuation chamber each having an entrance and an exit end. An inlet chamber, having a material flow path, is connected to the entrance end of the first attenuation chamber with a portion of the material flow path disposed at an angle to the flow axis. Connected to the exit end of the second attenuation chamber is an outlet chamber having a second material flow path; again at least a portion of the material flow path is at an angle to the material flow axis.
