How to solve the noise of cone crusher

As one of the important equipment for crushing, cone crusher has been playing an irreplaceable role. But sometimes in use for various reasons and produce noise problems, not only seriously affect the physical and mental health of the operator, but also cause serious noise pollution to the environment. Therefore, today to introduce the cone crusher noise causes and how to solve.

The reasons for the noise of cone crusher may be:

1. The fit clearance of each part of the machine. For example, the main shaft and cone liner clearance is not appropriate, the clearance is too large will cause operation instability, making the cone crusher body vibration, noise, while the clearance is too small is prone to cause shaft holding events. The clearance between the eccentric shaft sleeve and the frame bushing is too large, causing additional impact loads, which will also produce great noise. Or in the installation of the gear whether to destroy a pair of gears in the correct meshing conditions, so that the gear in the operation process to produce additional impact vibration and additional sliding wear, resulting in shortening the life of the gear, or even hit the teeth, etc., causing noise.

2. Motion analysis of the equipment. The unbalanced inertia force and moment of inertia in operation cause shock vibration and thus noise.

3. The processing precision of components is not high. For example, the gear processing precision is not high, resulting in the phenomenon of beating teeth in the work, resulting in noise. The unqualified design and processing of cone crusher parts, or poor precision, will lead to poor overall quality of the parts. It can be imagined that the installation to the equipment will affect the overall operation of the equipment, and the components in the weekly impact, but also constant friction, so that the noise of the equipment can not be eliminated fundamentally. Overall, the internal cause is not eliminated, the noise will continue to exist.

The solution of too much noise of cone crusher:

1. The mating clearance of the key components must be set according to the requirements. To eliminate the noise of spring cone crusher, firstly, the large and small bevel gears must be meshed correctly, eliminating the reciprocating sliding and additional impact between the gears, prolonging the service life of the gears and fundamentally eliminating the root cause of the noise. Select high-quality processing equipment to eliminate the internal cause of cone crusher noise.

2. Ensure that the clearance between the main shaft and the cone bushing and the eccentric bushing and the frame bushing is within a reasonable range.

3. Improve the processing precision of the crusher bevel gear to ensure uniform contact surface, prolong service life and avoid noise.
