PL-1200 ABSTRACT PL-1200 vertical lash crusher is a kind of light-structured and efficient machine, which can be applied to grind and comminute all kinds of minerals. Compared with other kinds of crusher, it is more proficient at grinding minerals, especially that of the secondary-solidity, special-grade solidity and caustic ones. It is mainly composed of bunker, stuff-dividing apparatus, rotor, whirlpool move tattering cavity, structure and driving apparatus. The whole working process can be described as follows: the rotor with radial-directional tunnel spin at a high speed in the whirlpool move tattering cavity, then remaining materials which can be made in the launching tunnel of rotor and tattering cavity develop into material-lining layer; the following step is that the materials launched out at a high speed come into crusher develop into consecutive downfall of stuff; at last, having been collided and comminuted in the whirlpool move tattering cavity for many times, the minerals can be grand fully. The grand-stuff can be excavated continually from the pumping-tunnel of the structure. Because the whole process is carried out between the materials, there is no metal erosions. So far, this machine is widely adopted in the technology of hand-made sand. Key words vertical lash crusher; whirlpool
