The balance state of Gravel And Sand Making Machine
Gravel And Sand Making Machine will produce unbalanced inertia force in the work, will produce vibration impact on the crusher, resulting in additional wear and damage, which requires us to analyze the balance state of the crusher, so as to ensure the normal operation of Gravel And Sand Making Machine.
When the Gravel And Sand Making Machine is crushing, the motor drives the eccentric sleeve to rotate through the transmission device, and the moving cone rotates and swings under the force of the eccentric shaft sleeve. The moving cone near the static cone becomes the crushing cavity, and the material is crushed by the multiple extrusion and impact of the moving cone and the static cone. When the moving cone leaves this section, the material which has been broken to the required size falls under its own gravity and is discharged from the bottom of the cone.
According to the analysis of the working principle of the Gravel And Sand Making Machine, the force acting on the moving cone and the eccentric sleeve are the inertia force of the moving cone, the dead weight of the moving cone, the inertia force of the eccentric sleeve and the inertia force of the balance weight. Based on this, and according to the torque equation of conical crusher, the following three equilibrium states are obtained.
The first one is that the balance weight is too light or there is no balance weight. At this point, the eccentric component movement state is that the spindle is pressed on the thin edge of the eccentric sleeve, and the thin edge of the eccentric sleeve is pressed on the straight bush, that is, the eccentric component gap remains on the right side.
The second is the larger balance weight. At this point, the eccentric component movement state is: the spindle is pressed on the thin side of the eccentric sleeve, the eccentric sleeve thick side is pressed on the straight bushing, that is, the gap between the spindle and the cone bushing is on the right side, and the gap between the eccentric sleeve and the straight bushing is on the left side.
Third: the crusher is completely balanced. But this situation is virtually impossible.
Under different working conditions and requirements, the Gravel And Sand Making Machine can choose different balance states according to the actual situation. Generally, if the requirement of finished product granularity of Gravel And Sand Making Machine is too high, the first balance state is recommended.
