The invention discloses a crushing method of
titanium sponge and the
crusher. The crushing method is as follow: a shearing apparatus is used to shear the
titanium sponge lump into blocks; then the blocks are sheared and
cut into smaller blocks in geometric dimension; the blocks are gradually sheared and
cut in this way, until the geometric dimension of the blocks meet the requirement. The
crusher comprises a
titanium sponge holder slide way and a push device, a lower blade arranged at the head of the holder slide way, and an upper shear arranged above the holder slide way, wherein, the upper blade is provided with a drive and transmission device used for driving the upper blade to do reciprocating movement; the edges of the upper blade and the lower blade are opposite and corresponding to each other; a limiting device of titanium sponge is arranged in front of the head of the holder slide way. The titanium sponge is crushed by means of shearing, so the blocks are free from
extrusion force, are not compacted, and increase slightly in density. Due to the blocks free from repeated
extrusion, the blocks temperature rise is slow, the temperature is low, and the blocks are oxidization resistant. The titanium sponge is sheared with
fixed length, the geometric dimension of the blocks are uniform, so the service performance of product is good and the yield is high but no
waste product. Only using the shearing
machine, the crushing method has the advantages of short technological process, high work efficiency and low cost.
