The materials firstly pass through a second jaw crusher with low crushing speed and high crushing force, and pass through a first jaw crusher with high crushing speed and small crushing force, so that the crushing of the alumina blocks with high hardness is finished, and the subsequent technological requirements are met.
Preferably, the first jaw crusher and the second jaw crusher share the same drive motor.
The output shaft of the driving motor is provided with a first driving belt pulley, the first driving belt pulley is connected with a first driven belt pulley through a first transmission belt, and the first driven belt pulley is connected with one end of an eccentric shaft of the first jaw crusher; the other end of the eccentric shaft of the first jaw crusher is provided with a second driving belt pulley, the second driving belt pulley is connected with a second driven belt pulley through a second driving belt, and the second driven belt pulley is connected with one end of the eccentric shaft of the second jaw crusher.
In addition, the balance wheel is arranged at the other end of the eccentric shaft of the second jaw crusher, so that the equipment is more stable in the working process.
The transmission ratio of the first driving belt pulley to the first driven belt pulley is 3:1, the diameter ratio of the first driven belt pulley to the second driving belt pulley is 3:1, and the transmission ratio of the second driving belt pulley to the second driven belt pulley is 3:1. Through such setting, increase the torque of second driven pulley, reduce the rotational speed of second driven pulley, better completion preliminary coarse crushing.
The first jaw crusher and the second jaw crusher are fixedly connected through a flange plate.
Compared with the prior art, the utility model has the following beneficial effects:
The jaw crusher for the chrome corundum raw material has reasonable structural design, ensures that two jaw crushes are connected in series and share the same driving device, and materials firstly pass through a second jaw crusher with low crushing speed and large crushing force and pass through a first jaw crusher with high crushing speed and small crushing force, so that the crushing of alumina blocks with high hardness is finished, the subsequent process requirements are met, the labor intensity is reduced, and the crushing efficiency is improved.
