Why does the cone crusher have a heavy load when running empty?

XinGaonai Heavy Industry will first take you to understand the working principle of the cone crusher. The cone crusher is a machine that puts the material into the crushing chamber and crushes the material through the friction between the cone and the crushed shell. The axis of the cone and the axis of the crushed shell maintain a certain inclination angle, so that the cone can form a conical crushing chamber when rotating.

Working Principle of Cone Crusher

The problem of heavy load when the cone crusher is running empty may be caused by many reasons, including but not limited to bearing clearance problems, lubrication system failures, equipment structure design problems, etc.

1. The role of friction

When the cone crusher is running empty, friction will produce a lot of resistance, resulting in increased load. This is because, in the empty state, because there is no material to crush, the friction will become particularly large, and the friction between the parts and components inside the machine that need oil lubrication will inevitably occur, resulting in increased load.

2. Lubrication system

Lubrication system failure is also a common cause of heavy load when the machine is running empty. If there is a problem with the lubrication system, such as a decrease in oil film strength or a decrease in heat exchanger efficiency, it may cause the oil temperature to rise, which in turn affects the normal operation of the equipment. The decrease in oil film strength and heat transfer efficiency may cause the equipment to be overloaded when running at no load.

3. Bearing clearance

Bearing clearance is an important factor affecting the stability of cone crusher operation. Too large or too small bearing clearance will affect the stable operation of the equipment. The clearance of non-adjustable bearings is determined after leaving the factory, while adjustable bearings allow the required clearance to be obtained by adjusting the relative axial position of the raceway. The selection of the optimal working clearance depends on the application conditions and the expected working state. If the clearance is not adjusted properly, it may cause excessive load when running at no load.

4. Equipment structure

Equipment structure design problems may also cause excessive load when running at no load. The equipment structure of some cone crushers may not be reasonable enough, so that the equipment will be subject to additional load when running at no load. If the installation clearance between the main shaft and the cone sleeve is too small, or due to wear caused by long-term use, this also leads to an increase in load when running at no load.

How do we avoid the heavy load of cone crusher when running empty?

   1. In order to reduce the influence of friction on the empty load, you can consider installing a lubrication system to release the friction and reduce the load.

   2. Adjust the bearing clearance to ensure stable operation of the equipment.

   3. In order to avoid the influence of the equipment structure on the empty load, the structure of the machine should be designed as reasonably as possible during design and manufacturing to avoid additional load and reduce the load.

In short, the heavy load of cone crusher when running empty is mainly caused by friction and equipment structure, but this situation can be effectively avoided by installing a lubrication system and designing a reasonable machine structure. When making these adjustments, you should ensure that you follow the equipment manufacturer's recommendations and safe operating procedures to avoid unnecessary damage to the equipment or affect production safety and improve production efficiency.
