The influence of material accumulation on the sand making machine rotor and its adjustment methods

The rotor is the core component of the sand making machine. Its main function is to drive the sand making machine to rotate at high speed, and use the inertial kinetic energy of the high-speed rotation of the rotor to impact, crush or shape the material. In actual production, if the internal accumulation of the rotor is ideal, the wear on the upper and lower wear plates should be uniform, and the rotor throwing head can be fully utilized, thereby reducing production consumption. Moreover, proper accumulation can protect the inner wall of the rotor, and more importantly, protect the rotor throwing head from direct wear and impact.

Although rotor accumulation is a normal phenomenon, the amount of accumulation should be appropriate, because insufficient accumulation will expose the throwing head, so that the large stones in the material are directly cut with the embedded head, resulting in premature wear of the throwing head, and then the throwing head falls off the clamping block grinding plate; too much accumulation will cause friction with the rotor, affecting the service life of the rotor. Therefore, too much or too little will affect the use of components, and then affect the performance and production efficiency of the equipment, and even bring safety hazards to production.

The impact of sand making machine rotor accumulation on equipment

Reduced equipment performance

Excessive accumulation of sand making machine rotors will lead to reduced equipment performance, which is mainly reflected in reduced production efficiency, insufficient proportion of fine sand, and product particle size that does not meet requirements.

Increased equipment maintenance costs

The accumulation of materials on the rotor of the sand making machine will accelerate the wear of the equipment (such as wear of the throwing head) and shorten the service life of the equipment. In addition, since the failure caused by the accumulation of materials requires special maintenance, the maintenance cost will also increase accordingly.

Production safety hazards

The accumulation of materials will also affect the vibration and noise of the sand making machine, making the equipment run unsteadily, and even cause equipment damage in severe cases. Excessive accumulation of materials on the rotor of the sand making machine will cause unstable factors such as vibration and noise during the operation of the equipment, making the equipment run unsteadily, and even cause equipment damage in severe cases, bringing safety hazards to production. Especially in some environments that require manual operation, the accumulation of materials may pose a threat to the safety of operators.

Adjustment method for accumulation of materials on the rotor of the sand making machine

Adjust the rotor

If the rotor that has just left the factory is not adjusted, it is generally difficult to achieve the ideal working state. Therefore, each rotor needs to be adjusted before it is put into use. In fact, rotor adjustment refers to the control of the accumulation of materials inside the rotor by changing the size, specification, position and shape of the guide plate to ensure that the material accumulation can be extended from the guide plate of the rotor to the throwing head embedded head, and the worn part remains in the middle of the throwing head. When there is too much material accumulation, you can try to increase the length of the guide plate or change the shape of the guide plate so that the accumulated material can be better discharged from the rotor; if there is too little material accumulation, you can reduce the length of the guide plate or change the shape of the guide plate so that the accumulated material can be better attached to the rotor.

Adjust the production process

You can also adapt to the operation requirements of the sand making machine by changing the feeding speed, feeding particle size and other parameters to prevent excessive material accumulation.

Regular inspection and cleaning

During the production process, it is necessary to regularly check the material accumulation of the sand making machine rotor. Once too much material accumulation is found, it should be cleaned up in time. Remember to pay attention to safety when cleaning to avoid equipment damage or personal injury due to improper operation.

Add auxiliary equipment

For some large sand making machines, simply adjusting the rotor and production process may not completely solve the problem of material accumulation. At this time, you can consider adding some auxiliary equipment to help solve the problem of material accumulation. For example, you can add a vibration device to help clean up the accumulated material, or add a heating device to make it easier for the accumulated material to fall off the rotor.
