The massive ore fall into the rejection material basin of the upper
crushing chamber rejection from the entrance.
The materials are thrown into the wall of cylinder rely on the
centrifugal force of the rejection material basin. And
they will have a violent collision with the counter board installed
on the wall. And the materials hit each other to
make them crushed and generate a large number of cracks. Then the
materials get into the conical rotor cavity and fall down as spiral
in cone space to make the ore with cracks getting further crushed
through stamping and
extrusion. As to the gradient between conical rotor and liner, the
minor material tend to move down to achieve
automatically graded broken from big to small. The materials are
blowed by the hammer in the conical rotor cavity and have another
collision with the high speed moving block materials. The material
flow hit each other to make them crushed through blowing, hitting,
shearing, extrusion, thus to improve the crushing efficiency. The
falling materials from conical rotor cavity get into the lower
crushing chamber and rely on the centrifugal force of the rejection
material basin to crush the material much smaller. At last, the
materials get into the cylindrical rotor to grind the crushed
materials for further crushing untill they reached the required
size.
