A particulate sizer includes an infeed for receiving a plurality of particulates, a first roller, and a second roller. The first and second rollers break down the plurality of particulates as the plurality of particulates passes through a gap between the first and second rollers. The width of the gap varies along a length of the first and second rollers. Accordingly, the first and second rollers compress some particulates to a first size and compress other particulates to a second smaller size. In addition, each of the first and second rollers has a textured outer surface for carrying the plurality of particulates through the gap.

A method for manufacturing a linear member reduces changes in the physical properties of a substance serving as a material for the linear member that may be caused when the substance is formed into a linear shape from powder. A manufacturing device usable for the method for manufacturing a linear member is a device for manufacturing a linear member having a predetermined function. The device includes a compressor. The compressor compresses, from an outer periphery of an elongated hollow body (9), the hollow body (9) accommodating powder of a substance having the predetermined function at an inner periphery of the hollow body (9) to compact the powder to allow the powder to substantially show the predetermined function. The linear member can be freely deformed while linearly accommodating the powder and maintaining the powder compacted. This structure can reduce changes in the physical properties of a substance in the linear member having the predetermined function that may be caused when the substance is formed into a linear shape from the powder.

A production method is provided. The production method comprises forming material by pressing or pulling ceramic material through a channel of an extrusion die, said channel being at least partly defined by the lateral surface area of at least one rotating die, and heat processing the formed material to form a ceramic product.
